Main Support Systems

351 Windsor Stroker Main Support System with custom ARP main stud hardware kit. Made of 3/4” Billet 6061-T6 aluminum, the D.S.S. Main Support System effectively dampens damaging harmonics, virtually eliminating main bearing walk. Why Are D.S.S. Main Supports So Important? It seems that everybody today is trying to get more and more power from their engines. Increasing engine RPM’s, or adding nitrous, turbos' or superchargers are some sure ways to increase power, but they can be very tough on durability. Additional stresses generated by running higher RPM’s or using power adders are transferred directly through the pistons, rods and crankshaft to the block’s main webbing. Commonly, the reciprocating force can overwhelm the main bearing caps and the fasteners that hold them in place. Under heavy loads, the caps will shift or “walk” from side to side. This movement is transferred to the ends of the main cap fasteners, causing the threads to become fatigued. Eventually the main web cracks, leading to a loss in oil pressure and possibly total destruction of the block and internal components. To combat this problem, Ford Racing offers Splayed Four-Bolt main racing blocks. While excellent pieces, the price puts them out of reach for the average enthusiast. This is where the D.S.S. Main Support System comes in. Starting at $399.95 the D.S.S. Main Support System is a very cost-effective way to add strength to a production block without breaking the bank.
