Anyone who wheels hard, rock crawls, or rock races has experienced blown up trunnion bearings, no matter what size bearings they are using, the bearing is always the point of failure. The Rock Assault™ Trunnion Bearing Eliminator Kit totally eliminates the bearings and replaces it with a solid king pin style pin that sits in a hardened bushing. The pin and bushing are made out of a material that is considered bearing quality because of its high carbon content, which gives it extreme hardness. To make sure these pins provide you with smooth steering we have added zerk grease fittings and machined the pins with grease passages and grooves so that they can easily be lubricated without any disassembly of the steering knuckle.
The Rock Assault™ Trunnion Bearing Eliminator Kit can be installed in a matter of hours and does not require you sending us your steering arms to be machined. You simply press out the pins in your 4 or 6 stud steering arms and press in the provided Trunnion Bearing Eliminator pins. The bottom pins have been preinstalled in the bottom caps and simply drop in after the lower bushings have been installed. Since you will need to disassemble your knuckle assembly to complete this install a full knuckle service kit is provided so that you can replace all seals, gaskets, and shims.
Due to various machining tolerances in the current steering arms on the market, some slight reaming may be required
