Rock Assault™ 9" Seal Housing Kit
Trail-Gear’s 9" Seal Housing Kit is machined from billet aluminum, has three o-rings on the outer surface of the seal housing, and has a double seal on the inside. The three outer o-rings keep the outer portion of the seal housing sealed up so that no fluid can leak or flow between the axle tube and the seal housing itself. The seal housing is tapered on the inside so that the axle shaft is lined up with the seal housing as it is installed to prevent damage to the seals or seal housing. The seal housing itself is secured in place with a set screw so that it cannot move or be pushed out of place when the axle shafts are installed. The inside of the seal housing has two seals installed to ensure that even while rock crawling on your side or racing at high speeds, no fluid leaks through or bypasses our seals. This will keep your fluid in your differential where it belongs, and not on your breaks and tires where it can create a dangerous situation.

The seals themselves are manufactured from a specially blended, high performance synthetic rubber that is so flexible that they can effectively seal any axle deflection, axle misalignment, or axle run out issues that may occur. The seal housing is shipped completely assembled with both seals installed, and replacement seals are also available, making the seal housing completely rebuildable. Our 9" seal housing will accommodate a 27 spline to a 35 spline axle shaft.

Seal housings are sold separately and two are needed to complete one axle housing. Seal housings are available for 3" and 3 1/2" tubing with either 1/4" or 3/8" wall thickness, and fit most of the popular aftermarket 9" axle housings being offered.
