JAP FITMENT PROMISE // If we confirm fitment for your rig and it doesn't fit, return shipping is on us. No restocking fee. That's the deal.

// GETTING IT TO YOUR GARAGE

THIS PART //

Ships UPS/FedEx ground — estimated $24.95. Additional ground items in the same order ship at reduced rates. Exact rate calculated at checkout.

REAL-COST SHIPPING

We charge what the carrier charges — no padding, no games. Ground parcels via UPS/FedEx, signature required. You see the exact number before you pay.

1-2 DAY HANDLING

Most in-stock parts leave the warehouse within 1-2 business days. Built-to-order parts show extended lead times.

LTL FREIGHT FOR THE BIG STUFF

Bumpers, hardtops, axles and full kits ship LTL truck freight (typically $400-500 per unit, plus shipping protection). Freight is charged per unit — two bumpers means two freight charges. Inspect before signing and note any damage on the delivery receipt.

30-DAY RETURNS

Unused, uninstalled parts in original packaging within 30 days. RMA required — start with a quick message. Shipping charges are non-refundable; freight returns quote at carrier rates.

// COVERED WHEN IT COUNTS

THIS PART //

Backed by the full Street Max 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.
