71 leaf spring truck. Lowering questions, 2.5 wide leaf spring swap??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The spring hangers on the two wheel drive and 4 wheel drive trucks are different heights. I’m not sure if the 2x4 Blazers had the narrow springs or not to source new spring hangers. The Longhorn 133” wheelbase trucks did have 2.5” springs so those hangers would work.

On my own truck, I kept the stock springs and ran a DJM flip kit with the CalTracs. FWIW, I used stock length front shocks on the rear and that worked great. The flip netted a 7.5” drop FWIW.
