1973-87 Blazer, Jimmy 3/4T 4WD Chevy, GMC Suspension
Suspension lift kits for your straight axle 4WD Chevy or GMC Blazer and Jimmy are available from 2.5" up to 8". The manufacturers found here can give your vehicle the look you want allowing for a larger tire and wheel combination plus increased ground clearance. Rough Country, Skyjacker, Zone Offroad, Superlift and Tuff Country have been providing suspension lifts for many years. They will get the job done!
The straight axle Blazer and Jimmy are fairly simple to lift. Replace the front leaf springs and use either a rear block kit, add-a-leafs or leaf springs to lift the rear. Add the steering correction recommended for the lift you choose and install longer shocks. That should do it. Now you're ready to just look good driving down the road or for some serious off-road adventure.
