The Teraflex 1155300 Leveling Kit raises the front of your Gladiator by 1.5 inches to achieve a level, aggressive stance. It corrects the factory rake, improving aesthetics and ground clearance without altering suspension geometry or ride quality.
Unlike low-quality spacers that compromise spring preload, Teraflex engineered this kit to retain OEM spring rates and shock travel. You’ll notice no harshness, sagging, or top-out under load.
The additional clearance allows installation of larger tires — typically up to 35 inches on factory wheels — with no rubbing or trimming required on most setups.
Each spacer is precision-molded from high-density composite material, designed to handle rugged off-road conditions and extreme temperature variation. Hardware is corrosion-resistant steel for longevity.
No cutting, welding, or modification required. Designed for straightforward installation with basic hand tools in approximately 2–3 hours.
The Teraflex 1.5" Leveling Kit delivers a balanced appearance and mild performance enhancement, making it one of the most popular suspension upgrades for the Jeep JT Gladiator platform.
Key Benefits Include:
Improved Stance: Levels front-to-rear height for a more aggressive look.
Increased Clearance: Adds 1.5" of space for better approach angles and tire travel.
Retains Comfort: Maintains factory ride quality and handling characteristics.
Cost-Effective Upgrade: Affordable, reliable solution for achieving mild lift goals.
OEM Compatibility: Works seamlessly with stock shocks, springs, and control arms.
Enhanced Appearance: Allows larger tires and improved visual proportion.
Proven Brand: Teraflex is an industry leader trusted by Jeep owners worldwide.
Ideal for daily drivers, weekend off-roaders, or anyone looking to improve the stance of their Gladiator without committing to a full suspension system.
