18x5" 100lbs/in Platinum Rear Spring by Eibach

Eibach has developed a new range of PLATINUM Series 18" x 5" race springs for Modified, Late Model and Stock Cars looking for lighter spring rate options.

With the overwhelming popularity of their current PLATINUM Series springs, Eibach found a need to push the range even further. These springs provide maximum grip levels at dynamic race conditions by combining the extreme travel of their proprietary Eibach PLATINUM spring wire in a new range of light spring rates.

These new rear springs pair perfectly with their Championship proven PLATINUM Series front springs for the winning edge over the competition.
