Suspension Lift ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

71BlazerSS · 10-29-2002, 05:54 PM

I recently bought a completely disassembled '71 Blazer. I want to lift it and have 35" BFGs for it. What is the best way to lift it and maintain a 'softer' ride and still allow room for the larger tires? I currently have 7 springs in the rear and 3 springs up front.

I am contemplating a 4" shackle-flip by Off-Road Design for the rear and have read that new springs are the best way to go on the front.

Any ideas or past experience?

The best way to do it is buy new springs for the front. You can buy a kit with the blocks for the rear. I have never done a shackle flip myself but i have never had a truck with a lift kit that had a soft ride. Just my 2cents. thanks

I've got their shackle flip on my truck and am happy with it but I found it moved my axle forward a little in the wheel well. I wouldn't like that on a Blazer. They do make a block that can move the axle back or forwards 1". Make sure your rear leafs are all fine. I had a crack in one of mine and I would probably have gone with new springs had I known that.

I'm very happy with my Tuff Country lift springs up front.

soft ride from a 71 blazer with a 4 inch lift ???? wat is that??? LOL have the same set up on mine and its not very soft but blazers are short and when you lift them they like to "buck" going down the road.I have a 71 short bed with 42s and 13" of lift that rides smoother but thats wat makes blazers so damm cool, bouncing, rataling, leaking blazers kick azz

Oh, 4" is close for 35" tires depending on the tire brand (they all differ on actual height) and rim width and backspacing. I wish I would ahve gone with 6" springs originally. You can see my install of the original lift on my 69 on a lift page on my website listed below.

I will 2nd Yukon about 4" with 35s i just changed mine to 6" superlift because the front tires rubed i had 35 bfg all terains with 8' rims

35s should fit with a 4" spging & a 2 or 3" body lift.

I run 35's with 4" on my Jimmy. The very slightly rub on the turned in lower part of the front fenders. I eventually plan to modify my fenders for clearance. I think 6" is too much, but 33's looked stupid on mine. 2 1/2" and 33's might be a good compromise. I would have done that with 3.7's, but with 4.10s I need the extra height. I would NOT even consider blocks as I had much problemas including bent axle housing perches. Yukon Jacks truck is a 3/4 ton, but the Blazer springs are wimpy so I don't suggest the shackle flip. I would run 4" lift HD springs in the rear and so-called softride springs in the front. It's not drastic, but best thing you can do is keep the center of gravity down. Best case would be no lift and 35's, but truck wouldn't look like much once you sawzalled enough clearance! When I get my truck really twisted, the tires jam into the rear of the front wells.
