52 F1 front spring shims
getting closer and closer to assembling the front axle / spring pack and getting it back on the frame after a good restore / repair / replace. I am going to use a set of 21y-5310 heavy duty 8 leaf c truck springs I picked up from Chuck to give the front a little more stance instead of having my standard c springs re-arched.
When I took my axle assembly apart, I didn't have spring wedges and the manual says they should be used. I have found both 2deg and 4deg at mid fifty, which should I use?

Caster wedges are used to increase straight line stability. If your truck goes down the road and needs constant steering wheel correction, the additional caster that they provide may help. Like Ross said, 'As needed."

Every one I've ever had apart (and that's been quite a few) has had the caster wedges installed from the factory. I cannot, however, tell you how many degrees of caster were provided by the original wedges though. It wasn't an extreme amount - likely about 2 degrees. A good general rule about caster is that it's difficult to end up with too much positive caster from a handling perspective. The more you have, the more of a tendency the front wheels will have to return to center. The downside is that steering effort increases with positive caster. A good target to shoot for is 4-7 degrees with power steering and 2-4 with manual. NEVER run one with negative caster! It will be difficult to keep running straight down the road.
