How to Get it

Free! Curbside & In-Store Pickup: Select A Store Near You

Ship to Home:

In-Stock Ships today ?

Fitment: Direct Fit
Set has one upper and one lower ball joint, two sets required per vehicle
New and improved ball joints
Compatible with all aftermarket axle shafts (including RCV) with no modifications needed
Fully greasable metal on metal design for prolonged life
Ball joint bearing surface area is considerably larger than stock due to elimination of the inner nylon liner for a longer lasting joint
Ball joint housing is manufactured from sintered graphite, bronze, and 1045 steel for a strong, smooth, bearing surface
Ball joint stud is manufactured from induction heat treated 4140 steel for maximum strength and smooth operation
Ball joint dust boot is made from wear/tear resistant black nitro-butile rubber (NBR)
12 month unlimited-warranty (see warranty information)
Synergy high performance grease (4119) recommended
Notes: Metal on metal ball joints require a small break-in period of typically 100-500 miles to fully "seat" the bearing surfaces. During this time the steering may feel "sticky" or slow to "return to center". Once broken in, the steering will be smooth and tight.

12 month unlimited-warranty (see warranty information)
Synergy high performance grease (4119) recommended
Notes: Metal on metal ball joints require a small break-in period of typically 100-500 miles to fully "seat" the bearing surfaces. During this time the steering may feel "sticky" or slow to "return to center". Once broken in, the steering will be smooth and tight.
