Synergy Manufacturing Non-Knurled HD Ball Joints - Set of 2

Do you have a new front axle housing or are looking to purchase your first set of replacement ball joints? If so, non-knurled ball joints are what you are looking for. Ball Joints are typically offered in two fitment styles, knurled and non-knurled. Synergy MFG has been making HD knurled ball joints for years intended as replacements for those looking for better ball joints after going through several sets of OEM style ball joints that simply don't hold up to the rigors of off-road use and large tires. Knurled ball joints allow the ball joints to still fit tight in the knuckle "C" bores after the bores have been enlarged from several sets of ball joints being pressed in and out. Knurled ball joints are a "fix" after non-knurled ball joints are no longer a sufficient press-fit.

Synergy MFG's new Non-Knurled HD Ball Joints are ball joints intended to be used in NEW front axle housings or replacing stock, non-knurled type ball joints. If your axle housing already has had knurled ball joints installed or you are on your umpteenth set of ball joints, these are not for you. Look into Synergy MFG's Knurled HD Ball Joints instead.

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.
