Datsun Roadster & Fairlady Rear Lowering Stock & Competition Rate

NOT to be confused with the Nissan Motorsports, NO ARC, 55020-25510 HARD springs that were sold by Nissan Motorsports.

These US made reproductions offer a ride height that will LOWER the car in the back with TWO different spring rates available to choose from. The 1st spring rate is a stock rate of 158 LBS. This will give you a nice balanced look when using lowering springs on the front and a comfortable ride in the back with good performance. In other words you will achieve the "Lowered competition look" without having a rougher ride in the back see 1st PHOTO: Our rear springs with a set of Mike Young Front Competition springs. 185/70/14 tires on 14 inch rims. We call these 55020-25511.

The 2nd spring rate is slightly higher at 185 LBS and offers the same ride height with better performance for track applications. We call this set 55020-25511C.

Both the 2117 and the 2117C spring sets come with the front bushings installed and are the same price.

Cosmetic duplication processes: Each leaf of the assembly was duplicated as close to the original as possible including the spacers between each leaf, and even the assembly brackets have been duplicated. The cups as pictured in the 2nd & 6th photos are no longer reproduced.
Our leaf spring sets come with the front spring bushings already installed. When comparing pricing, please note that pricing from other vendors of their spring sets reflects springs sold WITHOUT the front bushings installed

Manufacturing processes: Each leaf is made from 5160 American made raw steel and is formed on a jig with the correct arc at 1800 degrees. Each leaf is then oil quenched and drawn back through a furnace at 700 degrees. Degrees are approximate. The springs are then assembled as a unit and painted. 

Fender Measurements: Bottom of fender lip to ground measurements. Front: 24 1/2 / Rear 21 5/8.
