Synergy D30 / D44 Heavy Duty Front Ball Joint Sets - 8012-60

PRODUCT OVERVIEW

Replace your Jeep's factory ball joints with Synergy MFG's NEW Dana 30/44 Heavy Duty Ball Joint Set. These ball joints employ a metal on metal design to improve durability and performance. A must for vehicles with lifts and larger tires. Get rid of that steering wander and play caused by loose or worn out ball joints.

Synergy MFG's New And Improved ball joints are the result of actions that have been taken to address reports of premature wear on the previous iteration Product changes and manufacturing changes have both been made to guarantee you are getting the highest quality ball joints on the market.

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.
Knurled ball joints required when replacing knurled ball joints that have enlarged the axle end forging bores
Non-Knurled ball joints recommended for replacing non-knurled ball joints
Due to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
Use of the improper ball joint style for the axle housing voids our warranty. It is up to the installer to verify the proper ball joint style is being used.
8009-1201 ball joints have been superseded by 8009-1204.
4120-01 ball joints have been superseded by 4120-04.

*If you have older Synergy MFG 8009-1201 or 4120-01 ball joints that did not live up to your expectations, Synergy MFG has extended the warranty period for ball joints manufactured in 2016 and 2017 that experienced premature wear.
