Quality control
Every MAZ Muscle part is worked on and tested in-house before it ships. Panels are checked for fit, weave alignment and finish quality, and anything that falls short is reworked or does not leave the building.
Shipping
Hoods and large body panels ship crated by freight carrier. Smaller parts ship by FedEx, UPS or USPS, and a tracking number is emailed when your order ships. Please inspect your shipment on delivery and email photos of any damage to madhav@mazsupport.com within 48 hours so we can open a claim.
Installation requirements
All aftermarket hoods require hood pins, and heat shields are required on carbon fiber and fiberglass hoods. Damage caused by running a hood without hood pins or heat shields is not covered under warranty. We recommend a ceramic coating and polish before installation.
Fitment guarantee & warranty
Fitment is guaranteed on every part when installed properly. Discoloration is covered for 6 months from the date of delivery. See our Terms of Service and Return & Refund Policy for full details.
