Skyjacker® Rock Ready® ball joint load distribution design

Part# JK2717B

2007-2017 Jeep Wrangler JK

Upper Ball Joint, USA-made tapered roller bearing carries axial and radial loads. Polyurethane wipe seal prevents contamination – mounted internally to prevent tearing and friction between knuckle and ball joint face
Lower Ball Joint, HEXAD Grease System – 6 equally spaced grease grooves evenly distributes grease; With every turn of the wheel, grease is spread in between the two wear surfaces
32MM powdered metal bearing replaces the undersized OE plastic bearing, increasing load carrying capacity
Allows clearance for RCV axles without modification
Heavy Duty Load Carrying Upper Ball Joint
The Skyjacker® Rock Ready® ball joint design
shares the load between both the lower and upper ball joints significantly lengthening the life of both joints.
The OE ball joint design consists of a weight carrying lower ball joint and a follower upper ball joint. In this design the lower ball joint carries the full weight and road force of the Jeep and the upper ball joint is only a pivot point that controls lateral movement.
