COMPLETE MOSER 12 BOLT
Moser Engineering offers the best aftermarket 12 Bolt on the market. Our 12 Bolt housings are newly cast nodular iron housing units that are direct replacements for most leaf-spring, coil-spring, and torque arm General Motors OEM applications. The extremely durable housing units have giant caps utilizing half inch Allen bolts, and include perches or brackets. You have a choice of axles with pressed on ball bearings, or OEM style c-clip with c-clip retention. The units can be set up for anti-lock brakes and work with many OEM GM brake setups. Utilizing new housing ends adds to the simplicity and ease of installation, which is unparalleled in the industry. The complete package includes a Moser 12 Bolt housing, Custom Alloy Axles with ball bearings, studs and retainer plates. Also includes either a Moser full spool or a posi unit, Pro Street gears, 1350 series pinion yoke, chrome cover, and assembly. Brakes are not included. When ordering with a Moser full spool or a posi unit, you have the option of 30 spline axles or upgrade to our 33 spline axles, which carry a 10 year replacement warranty. However, if you are ordering the package with c-clip axles you can only order 30 spline axles. TWO-DAY TURNAROUND ON ALL ORDERS!
