With my 2003 4WD, two door LS Blazer about to turn 120K miles on the odometer, I am looking for some salvage yard upgrades. I keep thinking there has to be some Chevy Silverado's or vans with rear leaf springs that would bolt onto my Blazer without any mod's. I have some brand new rear shocks ready to go on at the same time. Any suggestions ? I don't do any heavy towing or hauling, except I like to carry around a good selection of hand tools in case of emergencies. I do very occasionally tow a single axle trailer for a light lawn mower. I keep noticing the rear springs have lost their arch and now look flat ! My LS is stock.

 

Have you thought about adding a leaf? Can just take one from a scrap yard blazer and slap it in, should get the arch back, and also stiffen the rear a little, not noticeable...

 

Thanks, DonL. I don't mind some rise in ride height and stiffness in ride at all. After 18 years on the road, my SUV's rear springs are sagging and that would be expected. In fact, I would welcome a little increase in ride stiffness and height. It is a slow and subtle change over 18 years and it would be great to have that 'like new' ride again. Plus many who have installed new springs will tell you for a while the new springs feel too harsh and have too much lift. That initial complaint goes away after a while. This may be due to the new springs 'settling in' or the driver getting used to the new feel or a combination..
I was hoping someone would come up with info such as a newer model Chevy/GM SUV , pick up, or van's rear springs would be a 'bolt in' for the 2nd Gen. two door with 4WD. There are a lot of them in the salvage yards.
