Front Coil Over Conversion Kit (Sleeves, Hats, & Collars) 911/914


This cost effective alternative, to buying threaded body struts, allows you to simply convert your current Bilstein struts to coil-overs for a fraction of the price.  Allows ride height to be adjusted with ease.

2.25" ID coil springs allow for spring rates greater than what is available in torsion bar
Upper spring hat features a proprietary design sealed thrust bearing, which proves to be the cleanest solution in steering/spring rotation.
Square threaded design is stronger and more resistant to dings, dirt, and binding associated with the traditional Bilstein RSR struts.  Square threads actually lock the spring perch in place under load, this is backed up by a nylon tipped set screw for extra security.
Shortened seal caps allow for more suspension travel.
All components are anodized for great durability and appearance.
Fits all 911 & 914 Bilstein struts.
Kit includes sleeves, thrust bearings, upper and lower spring seats, new strut seal, and weld on sleeve base rings.  Coil springs and optional tender spring spacers sold separately.
