ATV U-JOINTS
U-Joint & Yoke Assemblies. U-Joints are cold forged from SCM-415
steel, precision ground journals are case hardened to HRC58-61 U.
Joints are pre-greased with hi-temp Lithium Complex 3 grease. Bearing
cups feature a Quad lip seal to keep contamination out and grease
in. Centrally located grease zerk and grease channels in bearing cup
evenly distributes grease. Kits include cap plug to eliminate grease zerk
for low clearance applications. Honda Yoke assemblies have upgraded
cross diameters from 17mm to 19mm. Honda yoke assemblies feature
stainless steel clamps and hi-quality neoprene rubber boots for long life
and abrasion resistance.
