The JSPEC113PES delivers JKS long-arm geometry with Fox 2.5 Elite DSC reservoir shocks — driver-adjustable compression, superior heat dissipation, and a refined trail feel that the JK Unlimited platform is fully capable of exploiting. If you're running 35s or 37s on a 4-Door JK and want the best shock in the J-Konnect lineup, this is it.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with JKS long-arm caster and pinion correction. Fox 2.5 Elite DSC shocks give you on-the-fly compression adjustment — open it up for trail compliance, firm it up for highway stability. Adjustable upper and lower control arms allow precise alignment post-install. Axle wrap is eliminated and the JK 4-Door's longer wheelbase delivers a composed, planted ride at highway speeds with this geometry correction in place.\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 2007–2018 Jeep Wrangler JK 4-Door Unlimited (Sport, Sahara, Rubicon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e JK 2-Door | JL Wrangler (2018–2026) | Gladiator JT | Any JL variant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform Note:\u003c\/strong\u003e JK production ended 2018.

Professional 4-wheel alignment required post-installation. Torque all control arm hardware to JKS specification after a 500-mile break-in. Confirm DSC adjuster knob placement for driver accessibility during install. No cutting or welding required for standard JK 4-Door applications.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eEngineered for 35\"–37\" tires.

Confirm fender clearance with specific 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 Fox 2.5 Elite DSC tuning on a J-Konnect 3.5\" JK 4-Door versus a JK 2-Door — does the 4-Door's longer wheelbase and heavier curb weight require a different DSC baseline setting? Yes — the 4-Door's additional mass and longer wheelbase produce slower chassis pitch cycles but higher sustained shock loads, particularly at the rear. The DSC low-speed circuit baseline that works on a 2-Door will typically be too soft for a loaded 4-Door on the same terrain. Contact OFAS with your JK 4-Door's accessory weight and primary terrain and we'll give you a DSC starting position calibrated for the Unlimited's specific dynamics at 3.5\" of lift.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444664992065,"sku":"JSPEC113PES","price":4879.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC113PES_0-BKWD.jpg?v=1772726560","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec113pes","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
