These precision devices allow the spring end coils to tilt up to 4 degrees as the spring is compressed, reducing the bending loads on your shocks by as much as 96%. This reduction in side force and friction allows more force and energy to be directed to the car's mechanical grip while reducing wear on your shocks.
This model has a special 1.5" x 16 tpi female thread to fit the eyelet (shaft end) on Penske 8760 racing shocks. It is designed to replace the spring perch to minimize bulk. Sold individually. Anodizing color may vary from photo.
Installing a hydraulic perch at one end of the spring will reduce shock bending loads significantly; however, hydraulic perches at both ends of the spring will provide optimum performance. The Universal (Unthreaded) Hydraulic Spring Perch (Part No. 1870, sold separately) can be installed on the spring height adjuster (body) perch.
