Description
Power in All-Terrain. Ensure your RAM 3500 gets enough power in rough terrain by locking both axles with this ARB AAM 11.50-Inch Air Locker Differential. Designed to convert the differential from the conventional open type to a full spool type at the flick of the switch, this product will make sure all your truck’s power is transferred to the wheels even in the most challenging trails.
One-Touch Convenience. Engage this air locker easily with one click of the dash-mounted switch. No need to leave the comfort of the cabin so you can concentrate on the task at hand.
First-Rate Materials and Build. This air locker is made from alloy steel components for superior structural strength and performance. A 2-piece machined case is used to reduce moving parts, lengthen service life, and provide responsive actuation.
Installation by a Professional Advised. Due to the complex nature of the installation process, this air locker is best installed by a qualified professional. This kit requires a compatible onboard air compressor to actuate the locking mechanism.
Backed by a Manufacturer’s Warranty. This kit comes with a 5-year, no-mileage warranty so you’re assured that it’s free from defects in manufacturing and materials.
Application. This ARB AAM 11.50-Inch Air Locker Differential is designed to fit all 2003-2010 Dodge RAM 3500 models.
