The TeraFlex JK 4dr: 3" Coil Spring Base Kit includes just the basic lift components only and doesn-t have the drivability of a full suspension system. REQUIRES longer preset or adjustable control arms and adjustable front track bar to correct suspension geometry. Does NOT include shocks. We recommend Falcon Performance Shocks or TeraFlex 9550 VSS Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil springs to improve both compression and rebound for optimal vehicle stability. Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.

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.
