Fits select 2003-2017 Jeep Wrangler JK/Unlimited, Nissan Frontier, Pathfinder, Titan, and Xterra with Dana 44 rear differentials.

This Yukon Gear & Axle Crush Sleeve Eliminator Kit replaces the factory collapsible crush sleeve with a precision-machined solid spacer and shim pack. In high-torque or heavy off-road environments, standard crush sleeves can continue to compress under extreme load, leading to a loss of pinion preload, bearing failure, and gear misalignment. By installing a solid spacer, you ensure that pinion bearing preload remains constant regardless of the stress applied to the drivetrain.

This kit is a preferred upgrade for specialized builds, as it simplifies future maintenance; should a pinion seal need replacement, the solid spacer allows you to torque the pinion nut without the risk of over-crushing or needing to reset the entire gear pattern from scratch.

• Product Type: Rear Pinion Preload Solid Spacer & Shim Kit
• Replaces standard collapsible crush sleeves for improved reliability
• Ensures stable pinion bearing preload under heavy-duty use
• Application: Dana 44 Rear Differentials

By utilizing a solid spacer, you can achieve and maintain a consistent pinion preload that remains stable even under extreme conditions. This kit also simplifies future service; should you need to replace a pinion seal, you can simply re-torque the pinion nut without the need to install a new crush sleeve or re-verify the preload depth from scratch.

• Manufacturer Part Number: SK CSJK-F
• Component Type: Front Pinion Preload Solid Spacer & Shim Kit
• Axle Fitment: JK Dana 30, JL Dana 30, and JK Dana 44 Front
