TeraFlex LCG (Low Center-of-Gravity) Long Arm Suspension Systems are engineered for hardcore Jeepers who don-t want to give up on-road comfort and control in their TJ Wrangler/Unlimited. These complete systems include all necessary components including LCG Long Arm Brackets. Up front the Pro LCG expands the performance of the stock 5-link suspension configuration with our adjustable LCG Long Control Arms & Brackets. Our Front Upper LCG Long Control Arms are more than 9" longer than stock! Around back the stock 5-link rear suspension and track bar are replaced by our adjustable Pro LCG Triangulated 4-Link Long Control Arm Suspension w/ Rear Axle Truss & Brackets. The rear upper brackets feature adjustable anti-squat tunability to fine tune the suspension. Our adjustable LCG Long Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles anti-squat geometry and tire position on vehicles with 3-5" lifts. On higher lifts LCG Long Arm Brackets and 4-Link Rear Axle Truss reposition the frame-end control arm mounting points to relax suspension link angles. This reduces bushing stress during extreme droop as well as shock load transferred through the LCG Long Control Arms. The [High Steer] HD Adjustable Front Track Bar Drop Pitman Arm (4"+) and Rear Upper Pro LCG Triangulated 4-Link Control Arms improve steering response center the axles to optimize vehicle roll center and reduce body roll to for unsurpassed handling. This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems provide reduced noise vibration and harshness (NVH). TeraFlex Pro LCG Long Arm Suspension Systems are the best of both worlds!

TeraFlex Full Suspension Systems
TeraFlex full suspension systems are complete, engineered lift solutions built specifically for vehicle. Rather than a simple spring-and-spacer lift, each system is designed as a matched package: progressive-rate coil springs, tuned shocks, control arms, track bars, sway bar links, and the brackets and hardware needed to keep geometry correct at the new ride height. The result is added ground clearance and room for larger tires without sacrificing on-road manners.
Falcon Shocks by TeraFlex
Falcon Shocks are TeraFlex’s performance shock line, engineered from the ground up for specifically for your application. Each shock is a high pressure monotube design with a large diameter body, hard-chrome piston rod, and application-specific valving tuned to the weight, geometry, and suspension travel of the vehicle it’s built for—so the damping is right out of the box, whether your ride is stock height or lifted.
The lineup scales with how you drive. Entry-level monotubes sharpen control and comfort for daily driving and light trails, mid-tier models add larger bodies and more oil capacity for sustained off-road use, and top-of-the-range piggyback-reservoir shocks offer tool-free adjustable damping—plush for the highway, firm for towing, and full performance for desert and rock terrain.
TeraFlex Brake Kits
Bigger tires and added weight overwhelm factory brakes, so TeraFlex brake kits are engineered to restore and improve stopping power on lifted Jeep Wrangler and Gladiator models. The lineup ranges from bolt-on performance rotor and pad upgrades to complete big brake kits with oversized rotors, high-capacity calipers, and platform-specific brackets for greater clamping force and heat dissipation—plus extended braided stainless brake lines for lifted, long-travel suspensions. Every kit installs without cutting or fabrication and is built to handle off-road abuse, giving you stopping performance that matches your build, whether you’re on 35s or 40s.
