Coilover Sleeve Conversions Kits For Porsche 911/912/930

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.

Front Sleeve Conversion kit contains all these items:

Upper Perch – Extended to move spring below chassis on Bistein strut kits, 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.

Rear Coilover Sleeve Conversion Kit

Easy way to convert your existing non-threaded Bilstein (with 50mm body and 14mm rod) to full adjustable height coilover setup. No welding required. Can also be used with our Von Shock non-threaded shocks.

Upper Perch – Extended to move spring below chassis. Super extended upper perches are provided for ’65-’71 cars as they need more clearance.

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 clearance.

Snap Ring – Snap ring supports the threaded sleeve. Regular Bilstein shocks require a snap ring groove to be machined into the body. Optionally send your shocks to Elephant Racing for this operation. Von street shocks are pre-equipped with a snap ring and groove.

Instructions – kit includes full installation instructions.

Requires

  • 2.25 inch ID springs
  • Machined snap ring groove into 50mm shock body
  • Springs and dividers
