2013–2026 RAM 3500 HD – LOGIQ LEAF-ASSIST LOAD-LEVELING AIR SPRING KIT WITH 8,200 LB CAPACITY, HEAT WRAP INCLUDED & LIMITED LIFETIME WARRANTY

Transform your Ram 3500 HD's rear load-handling with the LOGIQ Air Spring Kit — a 100% factory-assembled, bolt-in leaf-assist air spring system engineered specifically for the Ram 3500 HD's heavy-duty leaf-spring rear suspension. Unlike the Ram 1500 and 2500 kits (which replace coil springs), this kit works WITH your factory leaf springs, mounting over the axle with a large-diameter, single air sleeve configuration that provides the ultimate blend of ride quality and load stability. Whether you're towing a 45ft fifth-wheel toy hauler with 2,800 lbs of pin weight on 1,200-mile hauls, running a Cummins diesel work truck, hauling heavy equipment on the jobsite, or managing serious gooseneck loads, LOGIQ delivers smarter, HD-grade air suspension that outperforms traditional helper bag kits by every measure.

Every detail is engineered for real-world Ram 3500 HD use. The OE-style LOGIQ air springs feature a low-frequency design for smooth, controlled ride performance even while towing and hauling tons of trailer. The large-diameter single air sleeve delivers up to 8,200 lbs of load capacity at 150 PSI, with a wide 5–150 PSI operating range that lets you dial in exactly the right ride height for any load condition. The design utilizes your factory bumpstops for maximum travel and preserves OEM axle articulation. Built-in locating features reference off the factory frame and leaf springs, guaranteeing proper fitment and operation on every install. Like the Ram 2500 kit, the Ram 3500 kit includes an Exhaust Heat Wrap Kit specifically designed to protect the air springs from tailpipe heat on the Ram HD platform (where the exhaust routing runs close to the air spring location) — a critical detail LOGIQ addresses that competitors ignore.

Pair the kit with your choice of LOGIQ Air Management Package (AMP) or run it with the included Manual Inflation Kit for app-free, wiring-free simplicity. The AirIQ HD2 (2-channel smart manifold with Heavy-Duty compressor, up to 2.5x faster than competitors) delivers best-in-class smart air control. The AirIQ SD2 pairs the same 2-channel smart manifold with the Standard Duty compressor. The AirIQ SD1 gives you a sophisticated 1-channel setup with paired rear controls. All AMP options are controlled via the free AirIQ App or the optional AirIQ Remote. Add the 2-Gallon Aluminum Boost Tank for lightning-fast lifts and sustained air delivery.

Specs

Features

• Leaf-Assist Load-Leveling System: Unlike the Ram 1500 (89-11090) and Ram 2500 (89-12140) kits that replace coil springs, the Ram 3500 kit is a leaf-assist system that works WITH your factory leaf springs. The air springs mount over the axle to add load support, correct sag, and level the truck under heavy loads — perfect for the 3500 HD's leaf-spring architecture.
• 8,200 lb Load Capacity at 150 PSI: Serious HD-grade load support. Handles heavy fifth-wheel pin weights, loaded flatbed cargo, work truck payloads, and real-world 3500-class towing scenarios.
• Wide 5–150 PSI Operating Range: The 5 PSI minimum (vs 20 PSI on the 1500/2500 kits) gives you more unloaded ride-quality flexibility. Run minimum pressure for empty cruising, dial up to 150 PSI for max load. Fine-tune to exactly the ride height you need.
• Large-Diameter Single Air Sleeve: The 3500's air sleeve design is engineered for maximum stability under HD loads. Single large-diameter sleeve provides more consistent pressure distribution and better load support than multi-chamber designs.
• Utilizes Factory Bumpstops: Preserves maximum axle travel and factory suspension geometry. No modification to bumpstops required — the kit works alongside your existing suspension stops.
• 100% Factory-Assembled Kit: Ships ready to bolt in — no field assembly, no shim stacking, no fabrication. One of the easiest airbag installs on the market per verified customer reviews.
• Exhaust Heat Wrap Kit INCLUDED: Ram 3500 HD exhaust routing passes close to the air spring location. LOGIQ includes an exhaust heat wrap kit to protect the air springs from radiant heat — ensuring long-term durability. Especially critical on Cummins diesel platforms where exhaust temperatures run high.
• OE-Style Low-Frequency Ride Quality: The LOGIQ air springs are tuned for OEM-like ride comfort unloaded, so you don't trade daily ride quality for load support.
• Axle-Mounted Inboard Frame Rails: Air springs mount inboard of the frame rails on the axle — HD-platform-specific mounting that differs from the 1500 (which mounts outboard). Optimized for Ram HD architecture and payload demands.
• Precision Fitment: Built-in locating features reference off the factory frame and leaf springs, guaranteeing proper fitment and operation for every install. No guesswork, no shimming.
• OEM Hitch Integration: Compatible with all OEM and aftermarket 5th wheel hitches and gooseneck setups. The LOGIQ system is designed to work alongside your existing hitch setup, not replace it or require modifications.
• Tested Tough: LOGIQ Air Spring Kits are universally validated to withstand the harshest HD conditions. Semi-trucks, buses, and trains have used air springs for decades because they outperform coils and traditional helper bags under load.
• Choice of Air Management: The default kit includes a Manual Inflation Kit (airline + Schrader valves + zip ties) for simple, wiring-free operation. Upgrade to one of three AirIQ Smart Air Management Packages for app and remote control.
• AirIQ HD2 (Optional): 2-channel Smart Manifold + Heavy-Duty compressor. Independent driver/passenger air control. Up to 2.5x faster than competitors.
• AirIQ SD2 (Optional): 2-channel Smart Manifold + Standard-Duty compressor. Independent driver/passenger control. 2x faster than competitors.
• AirIQ SD1 (Optional): 1-channel Smart Manifold + Standard-Duty compressor. Paired rear controls. Simple and sophisticated.
• AirIQ App Control: FREE download. Control inflation, deflation, presets, and monitoring from your phone. Save trailer-specific presets for one-tap towing setup.
• Optional AirIQ Remote: 2-channel wireless remote for app-free quick-access control.
• Optional 2-Gallon Boost Tank: Powder-coated aluminum air tank for faster lifts and sustained air delivery — especially useful on HD platforms with higher pressure demands.
• Spacer-Kit Flexibility: Multiple spacer kits available for different configurations:
  • 2WD trucks: Spacer Kit 88-13130-2WD required
  • 1" rear lift: Spacer Kit 88-13130-1 required
  • 2" rear lift: Spacer Kit 88-13130-2 required
  • 3–6" rear lift: Alternate kit 88-13130-LT required (not the base kit)
• Service Parts Readily Available: Verified customer review mentions that LOGIQ shipped a replacement air spring before the customer could even remove the old one — outstanding service parts and customer support.
• Limited Lifetime Warranty + FREE ReadyGUARD Coverage: LOGIQ air spring kits are backed by a Limited Lifetime Warranty on the air springs, PLUS a FREE 5-year / 60,000-mile ReadyGUARD powertrain warranty.

Fitment

FAQ

• Is this a helper air bag kit or a coil replacement? Neither in the traditional sense. The Ram 3500 kit is a leaf-assist load-leveling air spring system that works WITH your factory leaf springs. Unlike the Ram 1500 and 2500 kits (which replace coil springs with air springs as the primary suspension), the 3500 uses leaf springs — so this kit adds air springs over the axle to provide load support, correct sag, and level the truck under heavy loads. It's more sophisticated than a traditional helper bag kit (bigger, better-engineered, higher capacity) but it does work alongside your leaf springs rather than replacing them.
• Why is this kit different from the Ram 2500 kit? The Ram 2500 uses coil rear springs (uncommon for an HD truck), so LOGIQ designed a full coil replacement for it. The Ram 3500 uses leaf rear springs (traditional HD architecture), so LOGIQ designed a leaf-assist system that works alongside the leaf springs. Different trucks, different solutions — but same LOGIQ ecosystem and quality.
• Will this fit my 2013 Ram 3500? Only if you have the new-generation 2013 Ram 3500. 2013 was a transition year — early-production 2013s had the pre-refresh body. Only the new-generation 2013+ Ram 3500 (with the updated body style and interior) fits this kit. If you have an early 2013 with the old body, contact us about alternative SKUs.
• Will this fit my Ram 3500 Dually (DRW)? Yes. The DRW and SRW 3500 trucks share the same rear leaf-spring architecture and air spring mounting locations. The kit works on both configurations.
• Will this fit my Cab Chassis Ram 3500? No. Cab Chassis configurations (common for upfitters, service bodies, flatbeds, and commercial applications) use different frame and axle geometry. This kit is for pickup bed Ram 3500 trucks only.
• Will this fit my factory-air-suspension Ram 3500? No. If your Ram 3500 came with the optional factory 4-corner air suspension, this kit is NOT a compatible replacement. (Note: the Ram 2500 kit IS a direct factory air replacement, but the 3500 kit is not.) Contact us for alternatives.
• What spacer kit do I need?
  • Factory height, 4x4: No spacer needed. Base kit works as-is.
  • Factory height, 4x2 (2WD): Spacer Kit 88-13130-2WD required (sold separately).
  • 1" rear lift: Spacer Kit 88-13130-1 required (sold separately).
  • 2" rear lift: Spacer Kit 88-13130-2 required (sold separately).
  • 3"–6" rear lift: Use the alternate kit 88-13130-LT (NOT the base kit — the LT kit is engineered specifically for lifted applications).
• Will this fit my lifted Ram 3500? For 1" and 2" rear lifts, use the base kit with the appropriate spacer (88-13130-1 or 88-13130-2). For 3"–6" rear lifts, do NOT use the base kit — order the alternate LT kit (88-13130-LT) instead. Lifts over 6" require custom work — contact us.
• Does this fit my Ram 1500 or Ram 2500? No. The Ram 1500 uses the 89-11090 kit (coil replacement). The Ram 2500 uses the 89-12140 kit (also coil replacement). Each kit is engineered specifically for the platform's suspension architecture.
• Why is the heat wrap included? The Ram HD exhaust routing passes close to the air spring location. Prolonged exposure to radiant exhaust heat could degrade the air springs over time. The included Exhaust Heat Wrap Kit protects the air springs from this heat — especially important on Cummins diesel platforms where exhaust temperatures run high.
• Can the air springs go lower than the 1500/2500 kits? Yes. The Ram 3500 kit has a 5 PSI minimum pressure (vs 20 PSI on the 1500/2500 kits). This gives you more flexibility to run very low pressures for unloaded cruising ride quality.
• Do I need an Air Management Package to use this kit? No. The default option is the Manual Inflation Kit (included at no additional cost) — just a length of airline with Schrader valves. You inflate from any compressor (shop air, portable 12V pump, etc.) to your desired ride height. Simple, wiring-free, no app needed. Upgrade to an AirIQ AMP when you want smart on-board air with trailer presets.
• What's the difference between the AirIQ HD2, SD2, and SD1 Air Management options? All three provide smart app/remote control. The HD2 has a 2-channel smart manifold (independent driver/passenger control) and the Heavy-Duty compressor (2.5x faster than competitors). The SD2 has the same 2-channel manifold but with the Standard-Duty compressor (2x faster than competitors). The SD1 has a 1-channel manifold (paired rear control) with the Standard-Duty compressor. HD2 is the premium option; SD1 is the budget-friendly entry.
• Is the kit compatible with my 5th wheel or gooseneck hitch? Yes. The LOGIQ Air Spring Kit is compatible with ALL OEM and aftermarket 5th wheel hitches and gooseneck setups without modification. The air springs are axle-mounted, so they don't interfere with bed-mounted hitch hardware.
• What's the load capacity at lower PSI? Load capacity scales linearly with PSI. At 150 PSI maximum, the kit supports 8,200 lbs. At 100 PSI (roughly 2/3 max pressure), expect approximately 5,500 lbs. At 50 PSI, expect approximately 2,700 lbs. Always observe the 5 PSI minimum and 150 PSI maximum pressure limits, and never exceed your Ram 3500's GVWR or maximum payload.
• Can I use this to lower my truck for easier loading? Yes. At 5 PSI minimum pressure, you can lower the rear ride height for easier bed loading, 5th wheel hookup, gooseneck hookup, or trailer connection. The lower minimum pressure (vs 20 PSI on 1500/2500 kits) gives you more flexibility.
• How long does installation take? Verified customer reviews describe this as "hands-down the easiest airbag install I've ever done." Expect 3–5 hours for the air springs alone on the Ram 3500 HD. Add 3–4 hours for an AirIQ Air Management Package installation (electrical wiring, compressor mounting, air line routing).
• What's the warranty? LOGIQ Air Spring Kits come with a Limited Lifetime Warranty on the air springs themselves, PLUS a FREE 5-year / 60,000-mile ReadyGUARD Powertrain Warranty. One of the strongest warranty packages in the air suspension aftermarket.
• What if I develop a leak in an air spring? Verified customer review mentions LOGIQ shipped a replacement air spring before the customer could even remove the old one — outstanding service and parts availability. Replacement air springs are available directly from LOGIQ.
• Does the dual-spring layout affect my spare tire or exhaust? The air springs mount inboard of the frame rails over the axle. The kit is engineered to clear spare tire and factory exhaust routing, with the included heat wrap protecting from exhaust proximity. No modifications to factory accessories required.
