ECGS KP540 Builder Kit - 4.0" Tube

ECGS KP540 wheel end kit features 40 Spline 1550 U-Joint compatible Inner C's, Knuckles, Spindles, and Hubs. This development has created the strongest and most serviceable 1550 joint axle in the aftermarket today.

This kit comes complete from inner C to hub with options for High Steer Arms, and locking hubs or slugs. This is a wholly new design and components cannot be used with other set-ups, however, Our Inner C's are compatible with other 1550 joint KP wheel ends on the market. Featuring an industry first 40 spline locking hub, This kit is truly the next level of off-road axle engineering. This KP540 kit also shares Wheel bearings and spindle nuts with our 40 spline rear kit, allowing you to keep fewer parts on the shelf for service and fewer part numbers to remember!
