Bilstein shocks
- the best mass-produced shocks available for our cars. If you need an economy shock, Bilstein is the right choice. They provide excellent road feel and vehicle control for both street and track. Their inverted design reduces un-sprung weight providing improved suspension responsiveness. High pressure gas charge reduces foaming for consistent performance.
Bilstein shocks are available in three configurations: HD, Sport and RSR
|
Bilstein HD Shocks
HD shocks were a factory available performance upgrade on 911s and
standard equipment on 911 turbos. They provide good ride
quality and control for cars with stock torsion bars.
In-house services are available to upgrade, test, modify, and renew
your HD shocks.

Bilstein Sport Shocks
Sport shocks are a better match to cars with uprated torsion bars.
Sports are valved about 20% firmer (rebound) than HD.
In-house services are available to upgrade, test, modify, and renew
your Sport shocks.

Bilstein RSR Shocks
RSR rear shocks provide a threaded-body solution for coilover
conversions. RSR rear shocks are shorter than HD/Sport for better
fit to lowered cars, and they have a monoball lower mount.
We highly recommend custom valving your RSR rear shocks as the
standard valving is too soft. For more advanced threaded-body
and valving alternatives, see Von Shocks.
RSR threaded body struts are available on our struts page.
In-house services are available to upgrade, test, modify, and renew
your RSR shocks.
