The long shocks are not the root of the problem. The axles are too short. When I put my short shocks back on...the axle pins still barley engage the outdrives...sit right on the outdrive chamfer. The suspension geometry has been done well..so there is very little "plunge" movement between drive-shaft and outdrive cup. The drive shafts could be another 1/16 inch longer no problem...and this would make the outdrives last much longer.

Yes the the long shocks add to the root problem.

I gave up and bought a T/B2 for the dirt...hopefully the drive-shafts are sized better on that model. SC18 will be converted to an R2 as it can't handle anything but the smoothest dirt track conditions.
