Wrangler JL 2018-2026 Jeep 4WD - Front Adjustable Bump Stop Kit by JKS

JKS1140 Adjustable Bump Stop Extension Kit for Jeep Wrangler JL provides a precise solution for dialing in bump stop engagement on lifted suspension systems. Designed to work with most 2–6" lift kits, this interlocking, stackable system allows suspension travel to be optimized without unnecessarily limiting up-travel. Proper bump stop spacing is critical to prevent shock bottom-out, tire-to-fender contact, and suspension bind, and this kit gives you the flexibility to fine tune those limits based on your specific setup.

Unlike fixed-height spacers commonly included with lift kits, the JKS1140 system offers five selectable bump stop heights—2", 2.5", 3", 3.5", and 4"—allowing adjustments to match shock length, tire size, wheel backspacing, and overall suspension geometry. The interlocking design ensures secure engagement while maintaining strength and stability under heavy compression.

Installation is straightforward with included hardware, and once the base is installed, height adjustments can be made without removing the coil springs. Whether the goal is maximizing tire clearance or protecting critical suspension components, the JKS1140 Adjustable Bump Stop Kit delivers the flexibility needed to properly set up a Jeep Wrangler JL suspension system.
