The Only Gears With a 2 Year Warranty!
The Mark Williams 12" Modular is the only rear end in drag racing that offers a warranty on gear sets. That is how confident we are in the strength of our rear end.Every racer wants reliability and consistency, there is no better way to do it than with a modular rear from MW. The modular design makes it easy to dial in your car to your needs. You can change wheel widths, center widths, or even the mounting style. It is even easy to change from a flange axle to a floater.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 Mark Williams 12"
Engineered In-House specifically for High horsepower applications like Pro Mod, Top Alcohol Funny Car and Dragster, and more. Precise Alignment -Because 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 Weight -In many instances, a modular aluminum rear end housing is lighter than a comparable stamped or fabricated steel unit. This is obviously a performance advantage Long Gear Life -MW'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.
2 Year Warranty Against Gear Breakage
Industry exclusive2-year warranty against gear breakage on 12" gears used in a MW modular rear. Cost Effective -Not only are MW modular aluminum housings priced competitively with similarly equipped fabricated units, but the improvement in component life will pay big dividends. Wide Range of Gear Ratios -Variety of ratios available for 9", 9.5", 10",& MW 12" rears. Custom ratios available for 12" modular with minimum purchase of two sets and nominal development fee. Custom Made for YOUR Setup -Flanged or floater axles, steel or carbon brakes, 9" Ford, GM 12-Bolt, or MW 12" housing, 4-link or solid mount Engineered, Tested, & Manufactured In-House -Professionally setup by MW Technicians - Pinion support preload set by experienced staff at MW facility for easy installation in the field, backlash set for maximum gear life, all design work, R&D testing, and manufacturing done Louisville, CO - USA!
