// COVERED WHEN IT COUNTS

THIS PART //

Backed by the full Powertrax manufacturer warranty. JAP is an authorized dealer — your warranty is valid from day one.

FULL MANUFACTURER WARRANTY

Every part ships new in the box with the manufacturer's standard warranty — terms and duration vary by brand (typically 1 year to limited lifetime on hard parts). We only sell through authorized channels, so coverage is never voided by gray-market sourcing.

WE RUN THE CLAIM WITH YOU

Warranty issue? Don't fight the manufacturer's phone tree alone. Hit our team with your order number and photos — we open the claim with the brand and stay on it until it's resolved.

WHAT WARRANTY DOESN'T COVER

Defects in materials and workmanship are covered. Trail damage, improper installation, modification, and normal wear items (bushings, pads, wear plates) generally are not — that's standard across every brand we carry.

SEPARATE FROM RETURNS

Warranty claims (defects after use) and returns (unused parts within 30 days) are different lanes. Not sure which applies? Message us first — we'll route it the fast way.
