The JSPEC131PS delivers JKS J-Venture geometry-corrected control arms with Fox 2.5 Performance Series reservoir shocks, engineered specifically for the Gladiator's longer wheelbase and different suspension geometry compared to the Wrangler JL. The Gladiator's truck platform and longer wheelbase require a different geometry correction approach than the JL — this kit is built for the JT, not adapted from a JL kit.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3\" of lift with JKS J-Venture geometry correction calibrated for the Gladiator JT's longer wheelbase and truck suspension geometry. Fox 2.5 reservoir shocks deliver consistent damping and heat dissipation on extended trail runs. Adjustable control arms allow precise alignment post-install. The Gladiator's longer wheelbase provides a more stable platform at 3\" of lift than the shorter JL, with improved approach and departure angles for truck-specific trail use.\u003c\/p\u003e\n\n\u003ch3\u003eVerified Fitment (OFAS Standard)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e 2020–2026 Jeep Gladiator JT (Sport, Mojave, Rubicon, Overland)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e Wrangler JL (any variant — 2-Door, 4-Door, 4xe, EcoDiesel) | Wrangler JK (any year)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform Note:\u003c\/strong\u003e The Gladiator JT uses a different suspension geometry than the Wrangler JL.

Recommended backspacing: 4.5\"–4.75\" on a 17\"×9\" or 18\"×9\" wheel. The Gladiator's longer wheelbase provides more fender clearance than the JL at the same lift height — confirm tire brand and tread width before finalizing wheel selection.\u003c\/p\u003e\n\n\u003ch3\u003eEngineering Question\u003c\/h3\u003e\n\u003cblockquote\u003e\u003cp\u003eComparing the J-Venture 3\" on a Gladiator JT versus the J-Venture 3\" on a Wrangler JL 4-Door at the same lift height — how does the Gladiator's longer wheelbase and truck suspension geometry affect the geometry correction requirements and the Fox 2.5 reservoir shock's performance characteristics? The Gladiator's longer wheelbase produces slower chassis pitch cycles per trail obstacle than the JL 4-Door, which means the Fox 2.5 reservoir is working at lower shaft velocities per mile of trail on the JT than on the JL. The geometry correction requirements are also different — the JT's longer control arm travel arc requires different caster correction angles than the JL. This kit is engineered specifically for the JT's geometry, not adapted from a JL kit. Contact OFAS with your Gladiator's build spec and primary terrain and we'll confirm the right configuration for your specific JT build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444640579905,"sku":"JSPEC131PS","price":1894.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC131PS_0-BKWD.jpg?v=1772726239","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec131ps","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
