• Brand New Steering & Suspension Kit
  • Direct replacements
  • Built to strict quality control standards

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

An adjustable ball joint will look slightly different than a standard, non-adjustable version.  The stud will be offset once installed and can be rotated in order to allow a greater range of vehicle suspension alignment.

Direct Fit

Application-specific, with no modifications required.

Rigorously Tested

Made from higher quality materials than the competition. Built to have a longer life in any environment or road conditions.

State of the Art Manufacturing

By the same factories that the OEMs use.

Prepackaged for Your Convenience

Carefully assembled to include all of the parts you need, saving time and money.

All suspension parts received fit perfectly except the lower ball joints were incorrect type. The ball joints supplied were not the center type nail joint. I had to purchase one from Orielly.

2010 charger front suspension kit
I was skeptical at first because the price was so cheap"221.00 for over 1000.00 dollars worth of parts" but everything fit great, parts feel like high quality. Parts have only been installed for a couple days but so far so good, time will tell. But overall very happy with the product, quick shipping and I am looking at getting front struts for the same vehicle" 136.00 for both front quick struts" I give them thumbs up and would recommend them to other people

Steering and front suspension parts (Dodge Challenger)
Parts arrived in the time frame anticipated I was amazed at the warranty offer as well as the price of the parts so far no complaints other than the parts arrived in a boxed that looked like it fell out the truck and got rammed over but all the parts was accounted for and in good condition. Time will be the answer on how well the parts hold up the other good thing I can say is lifetime warranty on the parts is something you can't beat. Anyone willing to stick that kind of warranty on parts must have a good to decent product.
