Features
- Built for street and trail: TeraFlex designed Sport ST systems for a stable highway commute and comfortable trail performance.
- Lift coil springs set the height: TeraFlex lift coil springs provide the 2.5", 3.5" or 4.5" of lift; the Gladiator ST2 pairs springs with spacers.
- Supporting parts for each height: Each system adds the parts TeraFlex specifies for its height, such as Sport front lower arms on the JL ST2 or front drop brackets on ST3 and ST4. Each listing names them.
- Room for 35" tires and up: TeraFlex lists 35" tires on Sport/Sahara fenders for the JL ST2 and ST3 and 33-37" for ST4, with larger sizes on Rubicon fenders.
- Versions for every JL and JT: 2-door, 4-door, right-hand-drive and engine-specific versions, plus Gladiator systems with extended travel at 3.5" and 4.5".
- Shocks sold separately: No shocks come in the box; TeraFlex sells Falcon shocks and steering stabilizers separately.

About TeraFlex
TeraFlex describes itself as a Jeep company at heart, started and staffed by people who drive them. It designs, engineers and builds suspension systems, shocks, axles and performance parts, with the Wrangler and Gladiator at the center of the range.
The company traces its roots to the 1950s and MEPCO (Military Equipment Parts Company), an early supplier of Jeep parts. TeraFlex Manufacturing followed in 1996 to build heavy-duty suspension for the TJ Wrangler, and today's catalog runs from full lift systems and the Falcon shock line to axles, steering and armor.
Authorized TeraFlex dealer. Prestige Truck is an authorized TeraFlex dealer, so what we sell is new and genuine TeraFlex. In TeraFlex's words, its limited warranty extends "only to the consumer who originally purchased the product," so keep your receipt with your build records.
Frequently Asked Questions
Will this fit my 2020-2026 Jeep Gladiator JT?
Yes, if your Jeep matches the fitment table, and you choose the engine variant that matches it. If you're unsure, send us your VIN and we'll check.
What else do I need?
Shocks, which are not included; TeraFlex sells Falcon shocks separately.
What does Sport ST mean?
ST stands for Street & Trail. TeraFlex built these systems for a stable highway ride and comfortable trail manners, and its Alpine CT and RT systems build on the same foundation with adjustable arms.
Which lift height should I choose?
Pick by the tires you want to run. TeraFlex lists 33" tires on Sport/Sahara fenders at 1.5", 35" at 2.5" and 3.5", and 33-37" at 4.5" on the JL, with bump stop extensions set for each size. Each listing gives its own range.
Do I need new wheels?
On the JL systems TeraFlex calls for wheels with 4.75" backspacing or less, or its 1057000 offset wheel adapters on stock wheels. Each listing notes it where TeraFlex states it.
Are shocks included?
No. Every Sport ST system ships without shocks. TeraFlex sells Falcon shocks and steering stabilizers separately.
