You are currently viewing Ask Phil #14 – Hello Phil, I have a question regarding HD axles for an SR3 RS or RSX. Unfortunately, as you know, we cannot purchase any specifics parts for these axles from Radical, only complete units. Several of us have sourced the tripods to GKN, but we cannot find the specific inner CV hub that was used… Can you guide us in the right direction? Thanks in advance for your assistance. David I.

Hi David, 

Hope you are well. The inner tripod housing with the splined input shaft was originally from Ford Sierra European model at least) and diff size was 7” 

The early model Sierra was 6.5”, most popular and bigger spline section was 7”, and much larger “Scorpio” model was 7.5” (much larger).  

Hope this helps.

Kind regards

Phil Abbott
