Replacement & Return Policies


All parts carry manufacturer’s replacement policy, if any.

35 spline axles manufactured by Quality Body Shop Drivetrain will be replaced for a period of 10 years from the date of purchase if broken at the splined end due to excessive horsepower.  Axles damaged in ways not related to excessive horsepower will not be replaced. Axles cannot be modified in any way from their purchased state.  This includes, but is not limited to, redrilling, shortening, resplining, or welding.  Each purchased axle set will be replaced no more than once and will be exchanged for an equivalent set.

Axles other than 35 splines manufactured by Quality Body Shop Drivetrain will not be replaced if damaged.

Parts not matching the dimensional specifications provided at the time of order will be replaced or repaired, free of charge, if such flaws are discovered within 1 year of the time of purchase.

Parts shown to be faulty will be replaced or repaired, free of charge, if such flaws are discovered within 90 days of the time of purchase.

This replacement policy applies only to the original customer, and proof of purchase must be provided.  Proof of damage or faulty workmanship must also be supplied, which may include shipping parts back to Quality Body Shop Drivetrain for inspection.

The determination to replace a part according to the criteria of this policy will be the sole discretion of Quality Body Shop Drivetrain.
