Complete Modular Rears
The ORIGINAL...and still the BEST!Get optimum performance and reliability with MW Modular rears. They are stronger, lighter, and more efficient. This technology was created by Mark Williams, and has been refined over the years to remain the best on the market today. MW modular rears are manufactured from a special high-strength aerospace alloy that has proven to be far more rigid and precise than fabricated steel housings. We can use Ford 9", 9-1/2", and 10" or MW 12" gears, but the strongest, by far, are the MW 12" gears. The 12" pitch diameter gear in our housing uses a 40-spline pinion. The larger pinion gear and its 9" Ford hypoid position adds strength while the reduced outer perimeter of the ring gear lessens rotating mass and decreases overall weight. Every racer wants to get better over time, and there is no better way to do it than with a modular rear from MW. The modular design makes it easy to upgrade your current car or swap the unit to a different car if you need to. You can change the housing widths with end bells and spacers. You can change the mount between 4-link and solid-mount, and choose from a coupler or yoke setup for connection to the driveshaft.

VersatileWith MW's modular housing you can easily change end bells and mounting methods to accommodate a wide variety of applications. Many components are interchangeable so you can upgrade from a 9" (or 9.5") to 12" setup.EfficientBecause everything is precision CNC machined, component alignment is optimized to eliminate power-robbing friction. Moreover, the housings will not distort under hard acceleration, as is the case with many fabricated units.Light WeightIn many instances, a modular aluminum rear end housing is lighter than a comparable stamped or fabricated steel unit. This is obviously a performance advantageLong Gear LifeMW's 12" modulars have a 40-spline pinion with a 12" pitch diameter ring gear that has a reduced outer perimeter to lessen rotating mass and decrease overall weight. This larger pinion gear and its hypoid position coupled with precision alignment and rigidity of our housings allows racers to report significant improvements in ring & pinion gear life, and is why MW can offer a 2-year warranty against gear breakage when used in an MW modular. |  | ||||
