FAQ

Do I need to do anything special to run these?

No. They are assembled and ready to bolt on.

How are these different than your competitors?

1. We use ovaled springs, they use straight springs. Straight springs 'howl' while driving and are very irritating. Oval springs have greater travel.

2. Our competitor uses OEM top plates. These are not meant to support the weight of the car when used with a small diameter coil over spring and they fail. Our coil overs use a custom made top plate specifically designed for the application.

3. We use all custom designed poly bushings, bearings and components made for the Wbody. Our competitor uses parts from a handful of other vehicles rigged up to allow use on a Wbody.

Don't take our word for it, read the message forums. You'll save yourself a huge headache and a lot of money.

What's the difference between GR2 and AGX struts?

AGX's are KYBs best strut with an adjustable dampening rate. The GR2s are a OE replacment type strut performing about 10% better than stock.

Do I need the brackets?

The optional brackets allow connection of the rear sway bar. W/o them you cannot install your rear sway bar.

Are these different than what HT Motorsports offers?

No. They are manufacturing this product.
