Ultimate Racing offers a 5-year warranty on our quality and workmanship.

This includes parts that are made in-house by Ultimate Racing (i.e. Fabricated Piping, Welding, Machined Parts). If for any reason these parts should fail within this 5-year period, Ultimate Racing will repair or replace the part free of charge (in-bound and out-bound shipping and handling fees extra).

Warranty/Repair parts must first be returned to Ultimate Racing for inspection. Ultimate Racing will never ship a replacement product before receiving back the original.

All miscellaneous and extra expenses incurred as a result of the Warranty/Repair (workshop labor, vehicle downtime, etc) will never be reimbursed by Ultimate Racing.

All other parts (i.e. Turbo, Wastegate, etc) must fall under their respective manufacturer's warranty. If repairs are attempted by anyone other than Ultimate Racing or the respective manufacturer the warranty will be voided. Any damages as a result of misuse, abuse, or neglect will void the warranty as well.
