You will find Bilstein shocks as standard equipment on all the European sports and luxury cars. Now you can have Bilstein shocks for your street rod as well. Beautifully chrome plated. 7/16" top bushing and 5/8" bottom. The inner sleeve is 3/4" on these shocks so removing the sleeve will net a 3/4" I.D. and will not work on shock mounts with a smaller O.D. Main body is 8-3/4" long to the center of the mounting bushing.
