I installed a leveling kit in my Dodge 2 inch front 1.75 inch rear… The rear was done with a add-a- leaf and a 1 inch lifting block, The lifting block came out a Cummin 2500 1 inch spacer block non-tapered,
just curious what an acceptable pinion angle is or if I should get rid of the spacer block and purchase a tapered 1 inch total height lift block

 

with that small of a lift you should be fine. 4" is about the limit on crazy angle that what im runnin, unless you have vibrations, then you can just shim it to get the angle you want.

 

Are you having a vibe problem? From a stop and/or certain speed?

You don't want the angle difference between driveshaft angle and pinion angle to exceed 1.5*. I don't recall what it says in the factory service manual, but that's what my driveshaft shop directed when I set mine up.

 

Im not have any vibration issue at this point and I will check the angles

 

Even if you don't feel a vibration you might have one and any vibration will cause your u-joint to wear faster. As WK said your driveline should be within 1.5* of the pinion angle.

 

 

I've been having similar issues I'm trying to work out with my driveline and pinion angles. FWIW here's the 97 service manual on the subject I believe.
