TeraFlex JT Gladiator Leveling Kit — 1.5" Performance Spacer Front Lift, Fits Stock-Length Shocks

The TeraFlex 1155300 JT 1.5” Performance Spacer Leveling Kit raises a JT Gladiator’s front by 1.5 inches to clear larger tires and compensate for added front-end weight without replacing stock-length shocks.

If you want a subtle lift that increases clearance for up to 33" tires on Sport/Overland fenders (35" on Rubicon fenders) while keeping the factory or stock-length aftermarket shocks, this kit delivers a straightforward solution. It’s a spacer-style leveling system engineered to work with the JT Gladiator’s front coil springs to regain ride height lost to heavier bumpers, winches, or oversized spares. The package focuses on structural spacers, bumpstop extensions, and all required hardware — shocks are sold separately and Falcon Performance Shocks are recommended for those who want tuned damping.

How does this kit let me run larger tires without changing shocks?

The kit uses precision coil spring spacers to lift the front 1.5 inches, increasing tire-to-fender clearance without altering shock length. Because it preserves the stock shock mounting geometry and travel, you can keep factory shocks or use stock-length aftermarket units. If you add heavier accessories or drive aggressively on trails, consider matching the lift with performance shocks for improved damping.

• Includes 1" and 0.5" front coil spring spacers for a total 1.5" lift.
• Works with original or stock-length aftermarket shocks (shocks not included).
• Recommended pairing: Falcon Performance Shocks sold separately for better compression/rebound control.

What tire sizes and fender types will this kit support?

The leveling kit is rated to allow up to 33" diameter tires on Sport and Overland fenders and up to 35" on Rubicon fenders when using stock wheel backspacing. Tire fitment can change with wheel offset or different backspacing, so verify your wheel/tire combination before committing. If your wheels have less backspacing than stock, additional rear bump stop strike pad extensions may be needed to prevent inner fender rubbing during full articulation.

• Max tire diameter: 33" (Sport/Overland fenders), 35" (Rubicon fenders).
• Max diameter rating assumes stock wheel backspacing.
• Wheels with 4.5–5" backspacing may require rear 0.5" bump stop extensions (not included).

What hardware and components are included, and what’s not?

The kit contains the spacers and bump stop strike pad extensions required to achieve the 1.5" front lift plus the necessary fasteners for installation. It does not include shock absorbers, rear bump stop extensions, or any components related to changing wheel backspacing. Note that some plastic bumper configurations require removal of bumper-to-fender splash guards to clear very large tires.

• Included: 1" and 0.5" front coil spring spacers, two 1" front bump stop strike pad extensions, and all required hardware.
• Not included: shocks, rear bump stop extensions, wheel spacers, or splash guard removal tools.
• Install time: approximately 3 hours (3.5 hours if adding shocks).

Will installing this affect daily drivability or garage clearance?

The modest 1.5" front lift preserves most on-road handling characteristics while improving off-road clearance and load-carrying capability up front. Because the kit keeps shock length unchanged, steering geometry and ride height balance remain close to factory settings, minimizing changes to alignment and driveline angles. Always complete a post-install alignment and verify tire clearance with your chosen wheels and accessories.

• Minimal changes to steering geometry compared with larger lifts.
• Maintains compatibility with stock-length shocks and most factory settings.
• Post-install wheel alignment recommended.

Who is this for: The TeraFlex JT 1.5” Performance Spacer Leveling Kit suits JT Gladiator owners who want a practical front lift to fit larger tires, offset added bumper or winch weight, and keep family-friendly everyday usability. It’s ideal if you prefer a clean, simple spacer solution without altering shock length and want the option to upgrade to Falcon Performance Shocks later for enhanced damping.
