coil spring spacing

[tonyjklh]

while i save for a full lift kit i am planning on putting some 2" stacked washers under the coils for the front and some blocks in back. but i would like to know what degree alignment bushing will i need? also what size washer should i use(ID=?,OD=?)?

1-3/8" I.D. washers (O.D. is unimportant, as long as it's at least 3").

There's no way to know exactly what alignment bushings your truck will need until you get it on a rack and see where it's at currently.
If you want to buy bushings beforehand, best way to go about it is to get the 2-piece concentric fully-adjustable bushings. Note that they don't go quite as far offset as available single-piece fixed bushings, so there's a slightly greater chance you might not be able to align it afterward and will have to get the higher-offset fixed bushings anyway (Either that, take out a few washers until you can then align it. Stacking 2" worth will be too much anyway, as that would yield 3" of lift).

hard to find in the renovation center.the largest washer I could find of these 2 ½.. you'd have more luck at the center of the neighborhood nuts and Bolt
BOLT and NUT SUPPLY.

You should be able to get an inch to 1 1/8" of washer under the coil and still get the retainer nut back on. It was that way on both my 91 and my 97's.

if 2" worth of washers will be 3", how many inches of washers would be needed to gain about 2" total lift up front?

 

[4x4junkie]

About 1.33" worth.
The TTB beams (acting as levers) give you approximately a 1.5:1 lift height-to-spacer height ratio.

Nice thing with washers is you can play with different amounts of stacking them to get the height you want (or the highest that will work).

5or6 welded flat washer/depent their thickness

why does the inside diameter need to be 1-3/8" when the stud is only 5/8"?

the stud is 5/8" but it has another "hex" under the spring seat....

i think it is 3/4" stud that goes down into the beam, then the "hex", then the 5/8" that actually retains the spring....so you have to clear that other "hex" with the ID of the washers at 1 3/8"....

Exactly what John said, I just did it last weekend. Went pretty smoothly.
