RLD Performance is also a supplier for Mopar Performance Parts, GMPP Performance Parts and aftermarket parts from AFR, RHS, Manley, Ferrea, SI, Pioneer, Competition Cams, Crower, Callies, Mahle Motorsports, Diamond Pistons, Wiseco Pistons, Fluidamper, BLP Products, PRW, Yella Terra, FAST, ZEX and Powerhouse Tools.  Their web sites are linked on our "Contact Us" page for research purposes. Pioneer alone supplies so many quality product lines that it would be unreasonable to try to list their products.

RLD Performance is an automotive engineering business so your needs can be properly discussed and hard parts are sold appropriately and competitively. Parts are sold at Jobber or less like mail order, depending on the manufacturer.  However, there will be a lead time to supply the parts. 

RLD Performance is competitive on AFR cylinder heads and our own premium racing part lines. As a manufacturer, RLD Performance welcomes wholesale suppliers interested in stocking and reselling our premium line of late model racing valves, camshafts and spring kits.

RLD Performance can properly specify and upgrade your AFR cylinder heads or any other cylinder head, in house, where mail order companies cannot. Check our brief catalog listing, check the links for your part numbers and email or call us for final pricing as pricing can change from our suppliers at any given time.
