This rebuild kit contains the parts needed to service both fork legs, using durable materials to extend service life and bring back consistent damping and fork travel. It's a straightforward, cost-effective alternative to replacing entire fork assemblies.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit stop fork leaks and improve ride feel?\u003c\/h3\u003e\n\u003cp\u003eThe kit replaces the wear items that let oil escape and let dirt in: seals, bushings, and any required washers or retainers shown. New seals restore the oil barrier and new bushings reduce play between the stanchion and slider, returning proper damping and steering feedback. You get predictable compression and rebound again once the forks are rebuilt and filled to spec.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete seal set sized for 39mm forks — fits both legs\u003c\/li\u003e\n  \u003cli\u003ePrecision-molded sealing lips to resist oil seepage\u003c\/li\u003e\n  \u003cli\u003eReplacement bushings to reduce stanchion-to-slider wear\u003c\/li\u003e\n  \u003cli\u003eAll small hardware included as shown for a full rebuild\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich Harley models and years are compatible with the kit?\u003c\/h3\u003e\n\u003cp\u003eThis Jetuplusllc kit is engineered for Harley-Davidson 39mm front forks.
