H&R Sport Spring - 1981–1991 Mercedes-Benz SEC & SEL (W126, Self-Leveling)
This H&R Sport Spring is built for the non-diesel W126 Mercedes-Benz SEC and SEL equipped with the factory self-leveling rear suspension. It's a direct swap for the factory springs that lowers the car's ride height and center of gravity with a progressive spring rate.
As H&R's number one selling spring line, Sport is a clean, straightforward way to sharpen the stance of a W126-generation S-Class coupe or long-wheelbase sedan without disturbing the self-leveling system.
Why Sport Springs
H&R rates this set at roughly 1.4 inches of drop up front and 1.2 inches in the rear on self-leveling, non-diesel SEC and SEL models. The progressive spring rate keeps ride quality intact on a car built for comfort while noticeably tightening the stance.
Construction
- Cold-wound from H&R's 54SiCr6 spring steel
- Shot-peened, which H&R rates as more than doubling fatigue life over an unpeened spring
- 100% tested before leaving H&R's ISO9001-certified production facility in Germany
What's Included
- H&R Sport Spring, front and rear set
Reused from the vehicle: the factory self-leveling rear suspension and shocks. This spring is tuned to work with the factory self-leveling system.
Ownership Notes
We recommend a four-wheel alignment after installation to bring camber and toe back into spec at the new ride height.
