THE ULTIMATE KX500 SHIFT SHAFT KIT (1983-2004) | 4140 Chromoly Edition

THE FIX IS FINALLY HERE.

If you ride a KX500, you know the struggle. The OEM shift shafts are notorious for bending, stripping splines, and wearing out prematurely. For years, you’ve had to rely on overpriced NOS parts or questionable used eBay junk—until now.

We didn't just copy the factory part; we completely re-engineered it to handle the brutal torque and vibration of the mighty 500.

Why this is the best Shift Shaft on the planet:

• UNMATCHED STRENGTH: We ditched the soft factory steel for Heat-Treated 4140 Chromoly Steel. This shaft is designed to take a beating without bending or snapping.

• NEVER STRIP A SPLINE AGAIN: The 4140 material is significantly harder than OEM, meaning your shift lever stays tight and your splines stay sharp.

• PREMIUM COMPONENTS: Every secondary bracket and pin is machined from 304 Stainless Steel. No rust, no corrosion, just smooth action for years to come.

• READY TO RIP: This kit comes 100% Pre-Assembled. Don’t waste time pressing pins or fighting with springs. Pull your old unit out, slide this beast in, and go ride.

This is a Direct Replacement for all the following OEM Part Numbers: 92152-1075 | 13165-1122 | 92081-076 | 13161-1203 | 92145-1368 | 92027-1946

Fitment Note: The Upgrade You Need

Fits: Kawasaki KX500 (1983–2004)

ATTENTION 1983-1993 OWNERS: We engineered this shaft using the beefier, heavy-duty splines found on the later model KX500s. The early model (pre-94) splines were a weak point we refused to replicate.

• If you have a 1983-1993 bike: You MUST upgrade to a 1994-2004 shift lever to match this shaft. Do not try to force your old lever on; upgrade to the stronger modern standard and never look back.

Don't let a stripped shaft end your weekend. Upgrade to the Two-Strokes Only HD Kit and shift with confidence.
