Whats New


10" Pitch Diameter Ring Gears for 9" Thirdmembers
Mark Williams now offers race-ready 3rd members equipped with a beefy 10” pitch diameter ring gear (trimmed to 9.5”) that can be employed in the popular 9” Ford style rear end housing. This setup is ideally suited to ultra high horsepower applications like Pro Mod.
7075 Aluminum Accu-BondTM Driveshafts

These new 7075 alloy driveshafts are exclusive to MW, and feature our patented Accu-BondTM process for securing the yokes to the shaft. These are 61% stronger than our previous best, and can save approximately 50% of the weight over similar-sized steel shafts. Ideally suited for Pro Mod and other extreme horespower applications, these shafts are custom made and are balanced to G30 specifications at simulated operatiing conditions on our high-speed balancer.


Shot Peening

Mark Williams has been looking for current and new ways of making the best and strongest products available. We have been doing in-house heat treating for a long time. Now, we can do shot peening in-house, too. Shot peening enhanes the resistance to fatigue fracture and resistance to stress corrosion rather than strength or hardness, as does the heat treating process.

Horizontal Milling

We have expanded our shop inventory to include a new horizontal milling machine. This new machine has a high-speed (15,000 rpm) milling spindle, which allows each process that it performs to be completed faster and more efficiently. It has a 2,362 inches per minute rapid travers system, cutting cycle times down signifigantly. It also offers in-process probing to ensure precise machining.
