DSS Racing Main Support Systems

Made of 3/4'' Billet 6061-T6 aluminum, the D.S.S. Main Support System effectively dampens damaging harmonics, virtually eliminating main bearing walk. The Main Support Plate is fastened to the main caps using custom ARP main studs (included), effectively tying all five main caps together. By adding another main web structure you dramatically increase the block's strength, helping both block and crankshaft life. The Main Support System makes it possible to produce 650-plus horsepower from a production block.

DSS Racing Pro Windage Trays

The DSS Main Support System is a very effective oil scraper. The introduction of the DSS Pro-Tray just took it to the next level. Constructed from 1/4'' 6061 T6 billet aluminum, this bolt-on system makes all others obsolete. Our billet aluminum, full length, multi-level Pro-Tray offers the ultimate in windage control and fits most aftermarket and stock oil pans. The Pro-Tray is very effective at scraping off excess oil and removing air from the oil. Aeration of the oil is drastically reduced by shielding the rotating crank from the oil pan sump, protecting your expensive engine. This shielding also frees up horsepower by eliminating splash windage losses. The close proximity of these components and the free flowing one-way design removes horsepower-robbing windage. The Pro-Tray is a direct bolt-on accessory to our DSS Main Support System. The combination of added strength, longevity, and horsepower these two items bring to a stock block is a must for today's high tech, high horsepower combinations!
