AFR Warranty Information

Effective on purchase made on or after January 1, 2010, AFR warranties AFR aluminum cylinder head castings for the lifetime of the product with proof of purchase to the original purchaser. Additionally, valves, guides, valve seats, valve springs, retainers, locks, studs, guide plates, and valve seals are warranted for two years to the original purchaser with proof of purchase. All returns must have an RMA number from AFR in order to be returned to AFR. Parts must be returned prepaid freight by the original purchaser. When it has been determined, by AFR at its sole discretion, that the product does indeed have a warrantable problem from workmanship, materials, or an undetermined cause (mystery failure) AFR will repair at no charge and reimburse UPS ground freight and return UPS ground freight. AFR will repair or replace the casting at its option. This warranty doesn’t cover fitness for purpose and/or merchantability on any product sold by AFR. Non-AFR castings are covered by the manufacturer of that casting. Please call AFR directly at (877)892-8844 if you have questions about which manufacturer your head is made by.
