Shackle Lift and Pinion Angle
Hi everyone!
I'm looking into putting All Pro's 1.5 inch longer shackles on my 93 pickup to give the rear a bit of lift. The springs aren't sagging, but I want to lift the rear about 3/4 of an inch and crank the t-bars in the front to get about 1/2 an inch of lift. I've read a lot about shackle length affecting pinion angle. Will I be safe with a 1.5 inch longer shackle, or will I need a shim? I've seen that every inch of shackle equals about a degree of change in the pinion angle, so I'll get a difference of about 1.5 degrees. Also, will 1/2 inch of t bar lift in the front be safe? My t bars have never been touched so I assumed they're probably sagging slightly and are sitting a tad bit lower than factory height. Thanks!
