Our steering and suspension components come pre-greased, sealed for long life, and do not require the extra maintenance typically required by greasable versions.

Please Note: Whenever replacing steering components, it is highly recommended to have a professional alignment performed on the vehicle afterwards.  Failure to do so may result in issues with steering and premature tire wear.

Direct Fit

All parts are direct fit, application-specific parts with no modifications required

Rigorously Tested

Rigorously tested and made from higher quality materials than the competition. Our parts are built to have a longer life in any environment or road conditions.

State of the Art Manufacturing

Our parts are manufactured by some of the same factories that the OEMs use.

Prepackaged for Your Convenience

Our kits have been carefully put together to include all of the parts you need to get the job done, saving you both time and money. These kits also help take the guesswork out of finding the correct part for your vehicle’s steering or suspension system, allowing you to get started on your repair project faster.

Good fit, seems to last!
Installed two of these now. No issues on the first in 2 years. Second went right on and has done well so far. Hardest part is getting old parts off.

The kit is very nice. I haven't installed it yet. The only problem I have with it is that they don't all have grease fittings. The upper balljoints have grease fittings and the rest of the parts do not . That is why I only have it a 3 star. Chances are I will only use the upper ball joints and the stabilizer links unless I decide to drill and put grease fittings in the other ball joints and tie rods.

Good for the money!
Good product for the money! Everything bolted on with no issues.
The vehicle I put it on is a 2005 Tahoe with 220,XXX miles, so I didn't feel like spending a fortune on it. It would be nice if the kit came with the cam bolts and plates that set the caster and camber. At the very least, these should be suggested as something a person might need, especially in the rusty states.
I wish the fittings were all grease-able, but again, for the money, and where I was putting them, I am satisfied.

Ya'll must be 40+ years of age. It's nice to know there are still some of us out there that really want to help one another out by providing perfect parts, especially in a kit, and show us how to do it ( Great Videos ). I'm sure it saved me thousands. I don't mine paying for a shop to work on my vehicle, if you can find in honest one, and forget about taking it to a stealership. Thanks for looking out for the guy that likes working on his own vehicles.
I will definitely be getting my parts from ya'll.
P.S. You might want to think about doing kits for old tractors, Kubota, Cat 416, etc. Thanks TEXAS DAN

How do u install lower ball joints ?
Mark da shark on Feb 10, 2017
BEST ANSWER: The lower ball joints must be pressed into the lower control arm with use of a ball joint press. You may rent a kit at any local auto part store, and upon removal of the c-clip the process should be fairly easy to perform.
The upper ball joint started spinning with the stud, whiled tighting the castle nut. What's the problem? Is it the upper ball joint ? Factory promble?
Juan A on Mar 31, 2018
BEST ANSWER: Does the top of the ball joint stud have a set screw hole? If so you will have to hold down the stud using this hole with an allen wrench while using an open wrench on the castle nut.
Will this fit an 05 silverado 4wd with a 6 inch lift?
donni.17 on Nov 14, 2017
BEST ANSWER: Thank you for your question! All of our parts are made to factory spec, so if you have a 6" lift these will not work for you. We do not carry parts to accommodate that kind of lift.
