Re: Rear Axle Swap Questions!

2 wheel drive trucks use 42.5" spring centers and 4x4 uses 40.5". Four wheel drives and Longhorns use 2.5" wide springs and two wheel drive has 2.25" spring. 2 wheel drive is 5 lug and 4x4 is 6 lug, at least in the scenario of your truck and the Blazer. Long story short....No.
