THE STRONGER REAR-END REPLACEMENT! 

The Moser M9 is approx. the same weight as the stock 10 bolt, this makes it much lighter than most other 4th gen heavy duty replacement rear ends. 

All components are new manufactured items (No remanufactured, refurbished or rebuilt components).

• Perfect Drag Racing Setup for 10 Second (1/4 mile) & faster cars, along with weekend cruisers
• The Industries Strongest Torque Arm Assembly

The Moser M9 housings are made from 1/8" thick laser cut mild steel, which is fabricated from one Triangulated piece of metal and combined with a 3/8" thick face plate. The M9 comes standard with internal gussets and bulk heads. The Moser "M9" is ready to take on the toughest racing conditions. Seamless steel tubing (3" O.D., 1/4" wall), new brackets, new housing ends, and new bushings. Custom machined fill and drain bungs are standard on all M9's.

The Moser M9 Torque Arm Assembly will handle all you can throw at it! This package includes the highest quality fabricated housing on the planet utilizing a one piece triangulated housing, 3/8″ face-plate, gussets, bulk heads and each one is individually hand welded by the finest fabricating craftsmen in the industry. The Torque Arm in made from 1.25″ OD, 4130 chrome-moly tubing, all joints and connections including the 4130 chrome-moly threaded tube adapters are TIG welded. The 1 3/4″ x .095″ chrome-moly Cross member with integral torque arm mounting system further enhances the overall strength and integrity of the entire assembly.

Better Material, Better Production, Better Performance! The Moser M9 Torque Arm utilizes a unique Sliding front mount that allows the Torque Arm to move freely without binding, which would impair the overall handling of the car. The front slider has a grease zerk installed which allows for periodic lubrication maintenance. The Torque Arm itself mounts proprietorially to the M9 Housing via 3/16″ thick mounting tabs with two 3/4″-16 NFT x 5/8″ Bore x 7/8″ thick solid Steel Rod Ends. The Pinion Angle Adjuster, located between the bottom rear Solid Rod End and the bottom rear Torque Arm Tube, makes not only finding the correct pinion angle simple, but enhances the overall strength of the unit. The procedure for adjustment is simple, turn the adjuster ring and the angle can be changed up to 6 degrees! This assembly is patterned after the same style setup used in today’s Pro Mod cars. The Moser M9 Torque Arm assembly is not intended for the daily driver as it is all solid mounting components which provides no give and is typically too harsh and loud for expected daily driving expectations.
