I dont have it offhand but I have to ask why? Does it make a difference? NAPA sells the 2.5' shims is bronze. Real nice and cheap. WIll not crack. NAPA should be able to give you the details. The 2,5 and the 6 will be the exact same size except for the thickness difference
Cause I've a buddy who is a machinist, and can make them out of steel for nothing. Then I can play and see what shims I need, without buying a bunch. I can either have them welded to the perch, or have the perch moved and pass them on to someone esle who is in need. I did not realize NAPA has the bronze ones. Thanks!
I know some have used old spring stock (tapered), but I would still need the thick end measurements for 2.5 and 4, to have a starting point.
You should only need shims in the front if you changed your shackle length. I think it runs:
1 1/2 shackles - 2 degree shim
2 1/2 shackles - 4 degree shim
Could be wrong, also check your steering components for wear, worn parts show up more when geometry is changed. BTW shims are cheap, go buy some and you'll be sure of the correct thickness.
Just happened to be under the truck fixing a leaking fuel line, so I went ahead and measured mine which I believe are 2 degree shims. Thick part was about 1/4" thick by 5" long. Very hard to read the tape under there, but there's your answer.
I have bronze shims with zero issues.
For whoever it was that asked-I have 2.5 degree bronze shims from Napa on my 4" lift. Should be all you need unless you have the TPI lift. Tremendous improvement in tracking and general handling.
Let me put it this way. I will not waste his time, and will do all the legwork with dimensions, as he is working two jobs to keep a sick wife in medications. So you can call me the putz for looking to the LC community and the stats on line, instead of trying to figure it myself.
I'd do the math for you, I'm taking College Algebra/Trig right now...I'm not too dumb-got a 102% on my last trig test.
However, someone already posted the dimensions for their 2.5 degree shims, what more do you need?
