9.25 Pinion Angles: RC vs SB Pickup
« on: September 15, 2020, 05:55:30 am »
Do I understand that short-bed trucks use a double-cardan rear driveshaft where the RC uses u-joints on both ends?  And if so would one expect the pickup perches to be mounted to raise the pinion?

I ask because my RC had bad shaft vibes, washed out cap seat, and poorly matched angles.  So I installed a new double cardan shaft when I swapped new springs and now my angles are very close to optimal.  Springs did not change my pinion angle.  Wondering if the RC ended up with a truck 9.25 at some point.
