    My 72 Jimmy has the stock suspension and I would like to keep it that way. My rear end is sagging and I would like the truck to sit level. I have seen others with the same syndrome. I was wondering what the awnser is. I saw an ad for an outfit called National spring and they have a rear lift kit. Does anyone have experience with them?

    How much is it sagging. I used a 1" block on the rear and leveled out my blazer. It's easier than replacing the leaf spings and cheaper too.

    my 2 centavos...

    Like ARQ, I put a set of blocks in the back of my Blazer to level it out. I couldn't find 1" blocks locally, so I used 2" blocks and the thing has a tail-high rake now.

    Im not familar with this blocking . Is It a block between the leafspring and the rear? Can you fabricate it out of 1" steel? Loosen the u-bolts and slide it in?

    the block goes in between the leafs and the diff mount. if you look at some lifted trucks aound your area chances are they will have a larger block there. check it out next time you see a lifted truck somewhere in a parking lot or something.

    you could fab the block but you will need to add some guides. The top of the block has a hole the bottom has a guide. I think they are like close to 1/2 in diameter.

    I even saw an inexpensive set while waiting in the check-out line of the local Kragens, they were 1" or 1-1/2" and i thought they were only about $25.00?? they were listed as being used for pickups with added camper weight but if they had them for trucks our era they should go right on your blazer. I thought it had u-bolts & blocks in the kit?

    Those are exactly what I got when I got my lift blocks. Cheap-o units from Kragen. At the time, they only had 2" and 4" blocks.

    Make sure that whatever blocks you get have a locator pin that will mate with the hole in the spring pad on the rear axle and a corresponding hole in the other end that will mate with the locator pin in the spring. If they don't have the pin and/or hole, don't use them.
