Description
Teraflex HD Dana 30/44 Upper & Lower Ball Joint Kit without Knurl for 2008-2017 Jeep Wrangler JK, 2008-2017 Jeep Wrangler Unlimited JKU is a set of four heavy-duty ball joints for Dana 30 or Dana 44 front axles. This kit is engineered for the increased load caused by oversized tires and offset wheels.
The upper joints use extremely hard sintered wear bushings, magnesium phosphate coating, and heat treated 4140 chromoly ball studs with 1045 carbon steel housings. The lower joints add a hard alloy tool steel slotted wear plate, adjustable preload, dual zerk fitting access, and a low-profile dust seal design.
We recommend Ball Joints w/out Knurls (# 3442002 or # 3440000) as they will not score the inner knuckle & open up the bore.
Item # 3442002
We also offer Ball Joint w/ Knurls (# 3442022 or # 3440020) for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed in the past.
