Please note - Pricing can change due to price increases from our raw material suppliers on parts that we fabricate or from our manufacturers that supply us. We Try to remain as competitively as possible but may have to increase pricing without notice. This is not our desire but margins are so small that we cannot lose money on a transaction. We work very hard to accommodate our customers needs.

RLD Performance Parts and Aftermarket Parts

Please Note - We are primarily an automotive engineering business, not a parts warehouse. We stock only items that we manufacture like our upgrade spring kits and a limited supply of our Stage III cylinder heads. The majority of our parts lines are ordered from our manufacturers as needed so there is a short waiting period for the consumer. We do try to keep up. As our cylinder heads are built to order, the current lead time is 3-4 weeks. Realistically, AFR can be a 12-14 week lead time. All performance parts below are for off road use only unless specified. Some, but not all, AFR cylinder heads have California Air Resources Board approval.
