Restore absolute hydraulic fluid tracking and eliminate front-end play by installing the premium Moose Racing Off-Road Fork Bushing Rebuild Kit (Part #38-6128). Purpose-built for high-intensity motocross racing, open desert sand washes, and technical rock crawling loops, this comprehensive inner and outer bushing package replaces worn, flaking original components to bring factory-level steering 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 constructing this kit with high-purity copper-plated steel backings infused with a low-wear carbon-graphite PTFE (Teflon) overlay. This specialized material matrix reduces mechanical breakaway force, delivering a highly responsive front suspension feel over high-frequency chatter bumps and rough braking ruts.
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 AER, XACT (Air/Spring), and XPLOR front suspension architectures. It delivers direct factory-spec replacement fitment for the following off-road models:
Fitment Sizing Checklist: Unlike alternative single-leg kits, this Moose Racing package ships complete with exactly (2) performance inner bushings and (2) outer guide bushings to overhaul your entire front end. This kit is sized strictly for modern 48mm inner diameter (I.D.) front stanchion legs and will not fit older pre-2017 WP traditional spring forks or youth mini-moto dirt bikes. Please visually verify your fork dimensions before performing a 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.
