Jeep Wrangler YJ (1987–1995)
The YJ generation of the Jeep Wrangler (1987–1995) category collects all of the RockJock parts and upgrade kits designed to fit the YJ chassis precisely. Whether you’re restoring a well-loved older Jeep, upgrading suspension for tougher trails, or prepping for a lifted off-road build, this YJ-specific section helps you find the right components without guesswork.To ensure a successful installation and proper setup of your new components, please refer to our Instruction Manuals.
YJ Category Features
- Fitment & Compatibility - All parts in this category are engineered around the YJ’s suspension layout, stock axle specifications, frame dimensions, and mounting geometry - avoiding fitment issues common when mixing generic parts.
- Restore or Upgrade - All-Purpose Use - From OEM-replacement heavy duty shackles to sway-bar conversions, the YJ category supports maintenance and full custom builds.
- Components for Lifted & Off-Road Builds - Many YJ owners run lifts, larger tires, or upgraded suspension systems. RockJock’s YJ parts help ensure those mods maintain alignment, durability, and off-road capability.
- Wide Range of Parts - Easy Navigation - From basic suspension bushings to full Antirock sway kits or leaf-spring eye-bushing kits, this category gathers all YJ-specific items in one place - helpful for restorers, off-roaders, and custom-builders alike.You can also source these specialized parts and find professional installation support through our Dealer Locator.
Common Upgrade & Maintenance Groups for YJ
Here are typical parts/upgrade groups frequently used on YJ Wrangler builds:
- Greasable Leaf Spring Shackles - Heavy duty shackles with fluted, urethane bushings and complementing greasable urethane main eye spring bushings replace worn-out stock rubber bushings and improve ride quality and durability.
- Antirock® Sway Bar Kits - Bolt-on Antirock sway bar kit designed specifically for 1987–1995 YJ, offering improved off-road articulation and four-wheel traction while still usable on-road.
- Shock & Suspension Conversion Kits - Shock-mount conversions and upgraded shock kits (with compatible mount brackets) to support aftermarket, higher-travel, or heavy-duty shocks for lifted or off-road YJs.
- Heavy Duty & Lifted Motor Mounts - Replacement fabricated steel motor mounts with urethane bushings in stock height or 1” lifted are the smart decision to replace worn out motor mounts.
- Leaf Spring Plates - Front and rear heavy duty leaf spring plates offer robust, heavy steel fabricated construction and mounting options for shock mounts and stock front sway bar links.
Fitment & Build Considerations
- If doing a lift or suspension upgrade, be aware that modifications will change ride height, articulation, and possibly handling. Properly matched shocks, bushings, and geometry-correcting parts are important for safety and performance.
- Routine maintenance upgrades (like replacing leaf-spring bushings) can restore original ride quality - especially on older YJs whose bushings/hardware have degraded over time.
- Off-road builds often benefit from Antirock sway bars or upgraded suspensions - but such upgrades may increase body roll on-road; it’s a trade-off between off-road flexibility and on-road handling.
