Lowering front end of Peterbilt

22s, lp tires, lowest suspension setting and covered by full fenders should do the trick.

 

I took the blocks out of my 379. It was on low air, never had a driveline or ride heights issue. Spring shop shimmed it for me so the caster would be correct. Never had an issue.

 

I will have to dig for some before and after pictures. It did give it a slightly different look. I didn’t want a slammed look, just a little lower.

 

Any updates on this ? I have a '90 that i would like to lower also.

 

I never did that or want to. However the one I just put a spring in had about a 3 inch aluminum block between the axle and the spring.
If you took that to a machine shop that could cut that down an inch or two you would get your drop. Then your caster will be screwed up.

 

I THANK IT WOULD LOOK WRONG! Suit yourself but I would be more worried about causing vibrations, odd tire wear and such.
