Sleeve Conversion Kit Forumla
Coilover Sleeve Conversion Bilstein Strut

Complete your kit with spring options:

Main Spring - The finest springs available, Hypercoil. Choose from a broad selection of rates, here are a few popular choices:

200 lb - Street performance, canyon carver

300 lb - Autocross, Drivers Education

400 lb - Race

Helper Spring / Dividers - Prevents Main Spring from coming off perches at full suspension droop. Fully compressed in normal operation. Required for all but the softest springs. Divider ensures Main Spring and Helper Spring remain properly seated

Brake Line Support - Installing threaded sleeves requires removal of the stock brake line support. This kit is a clean way to support the line.

Front Coilover Sleeve Conversion Kit

Conversion kits provide a cost-effect way to convert to a full coilover setup while retaining your existing non-threaded Bilstein or Boge struts. Our no-weld kit converts regular Bilstein or Boge struts to full adjustable height coilover setup.

For Boge Struts

Sleeve Kit For Boge Struts For Porsche 911

Front Sleeve Conversion kit contains all these items:

Upper Perch - Extended to move spring below chassis, thus allowing max camber adjustment range. Choose perch for regular camber plates or QuickChange Camber Plate fitment.

Seat Bearing Kit - Prevents spring wind-up allowing ease-of-steering.

Strut inserts - Are not included. You may wish to purchase Von Shocks valved to match your chosen springs.

Strut Wiper - Shortens strut 3/4 inch for added travel, much needed on lowered cars.

Lower Perch - Easy height adjustment and corner balancing. Clamp-type is secure and kind to threads.

Threaded Sleeve - Provides height adjustability. Compact design fits 2.25 inch springs for superior tire clearance. Boge Struts require a 2.5" spring. The Boge kit comes with 2.25" to 2.5" spring adapter.

Sleeve Base - Slips on and positions threaded sleeve, no welding required.
