I have a 3" rustys full spring pack lift. its sagging a little. will 1" blocks and shims be alright? or will the geometry be unsafe ect.

 

Don't use blocks. Replace the springs.

 

See if the springs are still under warranty. Long shot but sometimes defective equipment makes it to the customer. Rear blocks are dangerous at best. They put serious stress under the springs especially if they are sagging already. Heck call rustys they might do you a deal on some new spring packs.

 

Very unusual for his springs to sag, how old are they? I'm going on 4 yrs. now on his 3" leafs now increased to 4 1/2" with Boomerang Shackles and zero sag. I keep my cargo area very heavily loaded all the time also.


His are one of the few company's that sell American made springs with his kits not like the others with the made in China springs.

 

Got 5 years on mine still going strong also.

 

I'm also curious to know how old they are

 

only a couple years. but my cargo area is loaded down pretty much all the time with jack tools tire ect. I measured it. it was level but from a distance appears to be sagging a little. the front flares are higher up than the rear and the vehicle itself is made for the back to be slightly higher than the front.


I already installed the blocks. when I put my rear bumper on ill prob replace the springs with a higher lift.


the top is before and the bottom after
