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
at leftis a new 1480 series transmission yoke P/N 39074.
Made from heat-treated billet 4140, this yoke is designed to
improve on standard 1480 components. 1480 series 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).
|M-W INTRODUCES NEW DRIVESHAFT
COMPONENTS WITH 1480 U-JOINTS
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
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
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
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.

Solid 1350 series 1310
A visual comparison of the various sizes of U-Joints. 1310 series U-joints
are stock in many applications, including early Camaros and Novas. The
size of the trunnion on the cross is where the U-Joint derives most
of its strength.
