Warranty

1-Year Warranty

What is covered

Our rebuilt cylinder heads, engines and I-Shift transmissions, and the parts we sell, are covered for 1 year — parts and our workmanship.

Installation requirements

Cylinder heads must be installed correctly by a qualified mechanic, always with a new head gasket and all new head bolts. Reused head bolts or an old gasket void the warranty.

How to make a claim

Call or text us at (215) 900-8872 with your invoice. We will inspect the part and make it right.
