- Porsche 944 1985.5-1991

Note: Will not fit 968 arms or new Porsche replacement arms made after 1998 as these arms are not rebuildable.
One Kit services both ball joints.

The pins are machined from a 4140/50 material called Accurloy. Accurloy was chosen because of it's ultra clean fine grain manufacturing process which ensures absolutely no carbon inclusions in the material. The pins are cut at the material delivered uniform hardness of Rockwell C 32 so there is no post heat treating process which could create material flaws in the finished parts.

The pin length is approximately 1.125" longer than the standard length pins. This allows for a corrected control arm geometry on cars lowered from 1.5" - 3" from the factory ride height. Factory ride height is measured with the control arm plane parallel to the ground (stock ball joints) at static suspension weight. To eliminate binding on cars on the lower end of the range a heavy enough spring rate should be used to keep the suspension travel from reaching the end of the ball joint pivot range.

The spindles must be machined at their clamping distance to be a true 19mm. This is done by first installing a standard 17mm ball pin to the spindle. With the pinch bolt torqued down you will need to measure the distance between the pinch gap. Remove the pin and shim the inside of the pinch to this measurement using a clamp to hold it in place. The 17mm bore must be aligned in a vertical mill, drilled undersized and reamed to 19mm.

Though the material we use is extremely tough it can be susceptible to fatigue fractures depending on track conditions and driving style. Though the pins will probably last much longer than a single season during the harshest conditions we strongly recommend they be replaced as part of an annual maintenance procedure. Reduced price pin replacement only kits are available to all previous customers.
