Bilstein Universal Motorsports Strut 46mm

Technical information, including what the valving numbers mean, is on our Bilstein 46mm Universal Strut Information Page.

Designed by BILSTEIN motorsports engineers, built in house by Streetwise around the Bilstein monotube insert, with Bilstein internals, seals and bushings. $725 each, one strut per corner of the car (not a pair). Lead time is typically 4 to 6 weeks. Custom builds are quoted individually. Email sales@streetwiseparts.com with the car and application first.

Rally, sports car, SCCA and NASA builders and fabricators get a universal 46mm motorsports strut built around BILSTEIN’s inverted tube technology, with a wide selection of travel lengths and valving options for building custom chassis where a bolt-on application would not work.

This semi-complete package can be adapted to most MacPherson strut suspension systems. Each strut is supplied with a matched external housing that permits the builder to fabricate weld tabs for mounting the unit to a vehicle’s lower steering knuckle. The strut insert is provided with a blank upper-stem that can be machined down to fit a specific top mount or camber/caster plate variation.

Utilizing the same technological design advantages as their gas pressure shock absorbers, the BILSTEIN monotube strut insert is installed with the piston rod at the base of the strut tube. Here the rod is completely protected from road contamination of any kind. Plus, the hard-chromed steel body of the damper provides superior strength to withstand the extreme side loads encountered in competition, delivering exceptional stability and greater performance.
