New 1480 Series Driveline Products

Your driveline isn't complete without improving on the transmission and pinion yokes. Our new pinion yoke features heat-treated billet 4140 construction. This yoke comes matched with MW chromoly caps for the best strength characteristics. Available in 35 spline (P/N 39072) or 9" Ford rears or 40 spline (P/N 39073) for MW 11" rears.

The next level of increased strength driveline components for Pro Mod, Outlaw and other 2,000-plus HP applications have been introduced by Mark Williams Enterprises.

M-W is now producing oversized transmission and differential yokes manufactured from heat-treated 4140 alloy, as well as companion 3-1/2” chromoly driveshafts (P/N 39880) that use 1480 series universal joints. They are 40% stronger than commonly used joints and driveshafts. The assembly is certified to meet SFI 43.1 specifications.

Transmission yokes are available for 1-3/8-16 spline Lenco and G-Force transmissions (p/n 39070), 1-3/8-32 spline Lenco (p/n 39071), and 32-spline Liberty and Jerico transmissions with roller bearing tail housings (p/n 39074). Pinion yokes are available for the 35-spline 9” Ford (p/n 39072) and 40-spline 11” M-W modular rear (p/n 39073). A matching steel billet U-bolt kit (p/n 39075) is employed with the pinion yokes.

In addition to chromoly, M-W also makes driveshafts from mild steel, 6061-T6 and Duralcan® MMC aluminum, plus carbon fiber materials. Mark Williams is also the first and only NHRA and IHRA Major Sponsor for driveshafts
