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.

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

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.

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.

Visa, Mastercard, Amex, Discover, Apple Pay, Google Pay and Link one-tap checkout — live in our Stripe checkout right now. Card numbers never touch our servers.

Klarna, Afterpay and Zip are active at checkout on eligible orders. Pick your split at payment — get the lift now, pay as you wheel. No JAP paperwork, approval happens right in checkout.

Pay with crypto directly in our Stripe checkout — select the crypto option at payment and settle in USDC and supported coins. On-chain payment, standard order flow, same warranty.

Every card payment runs Stripe Radar machine-learning fraud screening, with 3-D Secure (Visa Secure / Mastercard Identity Check) stepping in automatically when your bank requires it. Your card, verified by your bank.

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.

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.

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.

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.
