We recently received our first shipment of a new, low friction, rear spring mount that is based on the same Delrin and stainless steel design as the pintop shock mounts we distribute from Hardbar.  This mount allows free movement of the stock transverse rear leaf spring while removing the rubber or poly bushings usually used that can mask the real rate of the spring.  They can be used with any stock or aftermarket spring bolt up to 9/16" or 14 mm diameter.

Below are some pics of the kit but more information on this new product can be found on our website.

Retail price is $70 and they can be purchased directly at our online store.

Very cool!

Yup! I kind of like the idea. The shock mounts are sweet too, its a shame they cost so damn much! No relief for C4 modifications. Might order a set of these to lower the rear plus have the added benefit of the delrin bushings.

There's friction in the rear spring bolt bushings?

Friction isn't a problem in the axial function of the bushing but compression of the bushing is.

The low friction comes into play now that the mounts are incompressible. I wanted to make sure that if there was any sliding that needed to take place that it would happen as freely as possible.

We've revamped the kit a little to reduce the price and enable the kit to be used with the stock style and most aftermarket bolt springs on the market. I've updated the OP.

If you have any questions be sure to ask!
