Features & Product Details

TeraFlex JL / JT: HD Ball Joints are engineered to handle the increased load caused by oversized tires and offset wheels. Fits all JL Wrangler/Unlimited and JT Gladiator models with Dana 30 or Dana 44 front axles.

Features and Benefits

30mm (1.18”) adjustable ball stud for accurate initial and future preload adjustments using simple hand tools

Heat-treated 4140 chromoly ball studs

Heat-treated 1045 carbon steel housing and threaded retaining ring

Magnesium Phosphate coating provides corrosion resistance and decreases friction

Hard alloy tool steel slotted wear plate for ball stud to socket wear protection

Wear plate features dual helical grease channels for increased flow through entire joint ensuring longevity and predictable operation

Grease channels also allow spent grease to exit through low-profile seal

Includes factory style slotted nuts and cotter pins

Low-profile single lip dust seal prevents contaminants and eliminates concerns for torn conventional dust boots

Heavy-duty snap ring on upper ball joint prevents ball joint separation from the axle during extreme off-roading

Ball joint preload adjustability provides the end user with near effortless wear adjustment

Preload adjustment requires simple tools and can be performed with the vehicle on the ground

Simple locking mechanism w/ 1 screw and revised geometry so adjustment tool doesn’t slip as easily

2 grease zerk fittings allow greasing access from either side

Notes:

• Ball Joints w/out Knurl won’t score the inner knuckle and open the bore.

• Ball Joints w/ Knurl are for inner knuckles that have a “loose press fit” due to repeated ball joint replacement and/or where knurled ball joints have been installed.

70k miles on my JT and the factory ball joints were used up. I was upgrading to 37" tires and these were a much needed upgrade.

Typical Teraflex 6 months ago

I ordered these as part of a full steering setup replacement. In my experience they feel like a typical high quality Teraflex product. It is unbelievable the difference between these and stock. Highly recommend.

Great Ball Joints 8 months ago

These are a great upgrade to my husband's Jeep JLU. He really likes the increased flexability and the reinforced durability that these offer. Installing did take a little longer than expected, but honestly when doing a self install that is normal.

If you’re going to replace ball joints, these are the way to go. Heavy duty and can be greased.

Tereflex HD Ball Joints 1 year ago

I kept going back a forth between these and another brand that was more than twice expensive. My JT has 20k miles and with running 37” tires I figured it was time. In the short time I’ve had them installed it is night and day difference. Tighter steering and a lot less road harshness. Install was just as expected with any ball joint. About 3 hours taking my time. Beware when installing you don’t collapse the threaded holes for the grease fittings on top. Short term these are great, long term, we will see how they hold up.
