Trail-Gear introduces a new concept to the axle housing design. This exclusive design features axle tubes that have been offset above the housing centerline making the inner axle shafts ride near the bottom of the axle tubes rather than in the center. This repositioning of the axle tube results are an increase of 3/8in. ground clearance under the axle tubing. Trail Gear uses axle tubes made from 5/16in.thick, high strength DOM steel tubing and engage 5/8in. farther into the center section. On top of that, there is a 360 degree gusset welded around the tubes on the inside of the housing to ensure unparalleled strength. The heavy-duty, press formed, 1/4in. plate steel center section shell is specially shaped to ensure a minimum of 3/4in. additional clearance under the differential. The differential mounting surface is made from 1/4 in. plate steel to ensure studs can not pull out, even under heavy loads. The outer offset flanges are made from 4130 Chromoly to prevent distortion or bending. Housings are precision aligned using start-of-the-art, 3D digital imaging equipment.
