Eliminate front-end slop, reduce steering deflection, and restore plush hydraulic compliance to your suspension by installing the premium Moose Racing Off-Road Fork Bushing Rebuild Kit (Part #38-6157). Purpose-built for competitive off-road racers and dual-sport riders, this comprehensive inner and outer bushing package replaces worn, flaking original components to bring factory-level tracking precision back to your motorcycle's front suspension assembly.
Worn suspension bushings create microscopic play between your inner and outer fork tubes, causing your front axle to twist under heavy braking and slide out of tight ruts. This internal slop also creates uneven lateral loading on your fork seals, forcing the rubber lips to roll or leak fluid prematurely. Moose Racing completely corrects this structural wear by dyno-testing and matching each bushing to exact OEM friction standards. The core rings are wrapped in a highly specialized, low-friction carbon-graphite PTFE (Teflon) composite matrix that drastically lowers breakaway stiction, yielding a highly responsive front suspension feel over high-frequency track chatter and hard landing impacts.
Unlike cheap, non-plated replacement hardware that can flake away and clog your internal valving shim stacks, these inner slide and outer guide bushings undergo a multi-stage copper shell plating process. This protective layer ensures absolute dimensional stability under severe mechanical heat and side-loading shear forces. The master axle kit ships complete with all necessary copper crush washers, retaining rings, and replacement backup seals, providing a seamless workbench rebuild workflow with zero trips to the parts counter.
This premium 48mm axle rebuild kit is engineered to restore original factory tolerances to WP 48mm Open Chamber, Closed Chamber (Bladder), and 4CS front suspension architectures. It delivers direct factory-spec replacement fitment for the following off-road models:
Fitment Sizing Checklist: This rebuild hardware set is custom-tailored strictly for the inner and outer diameters of 48mm WP traditional spring forks. It will not accommodate alternative fork brands like Showa or KYB, nor will it fit modern WP XACT Air forks (2017+) or youth mini-moto dirt bikes. Please verify your exact suspension architecture and model year profile before running a workbench teardown.
Fitment Sizing Profile: This hardware kit is custom-tailored strictly to fit specific structural fork tube inner and outer diameters. It will not accommodate youth mini-moto bikes running downsized stanchions. Please cross-reference your motorcycle's exact year, make, and model family against the Moose Racing master catalog application matrix to confirm exact fitment data before performing a workbench teardown.
Pro Maintenance Tip: Suspension and steering safety is paramount. During the fork rebuild process, thoroughly scrub the internal walls of the outer aluminum fork slider tubes with a non-abrasive hone or clean cloth to clear away old metal friction paste. Prior to final assembly slide tracking, always apply a light coating of clean, high-grade synthetic fork fluid directly onto the new PTFE bushing faces to guarantee an absolute zero-drag startup.
Don't let a sloppy front end or sticky fork action rob you of cornering traction on a prime riding weekend.
