Alright, I've gotta put it out there first off: I don't really like the idea of body lifts. I don't like the idea of taking away the support of the frame rails, but this opinion is coming from full sized pick-ups, which is why I bring up the issue.

How well would a (mild 1" max)body lift support weight in an SUV(specifically a '92 4Runner)? Because all the weight is being put right onto the body mounts(what 6x 3sq/in blocks?) is there any risk of damage when you really load up?

I've gotten my runner loaded up pretty heavy(people, guns, dead animals, ammo, kit, wood, cultivator shovels, fertilizer, etc), and I'm concerned that with a lot of weight and if I go offroad or even just bounce around I'll risk putting a body mount through the floor.

That's the last thing you have to worry about, there shouldn't be any reason for anything to go through the floor. If you get a quality body lift, there isn't anything to worry about.

I wheeled the crap out my my '92...numerous times i've bounced it up and through rocks, teeter tottered it, and even jumped it. All that was with 33's and a 1" 4crawler BL. Never had any issues. If the pucks were aluminum, i'd probably be worried but polyurethane kinda helps absorb vibrations, jolts, etc...

Right. The people that have to worry are those that are trying to use things like hockey pucks or wood blocks to do a BL.

Buy a good kit (4Crawler is top around here in our books) and you won't have any worries.

The weight is always on the body mounts...

thats what i was thinking too... there is always a gap between the body and the frame.. when you add a BL you just make that gap bigger...

RB designed wider lift blocks to avoid that kind of stress.

4crawler >>> your favorite brand.

I had a '90 truck with a 3" body lift for 10 years. I do construction and had it loaded regularly, several times I had over half a ton in the back. I also took it wheeling a lot, sometimes pretty hairy. Never had any problems at all.

The 4Runner has 10 body mounts that the body rests on (yes the '96 and 4th gens have only 8). There is also often a location in the rear wheel wells where the body rests on the frame. I've run a 3" body lift for years now and did add bed spacers to support the bed under the rear wheel well area:



As long as the body lift blocks are at least as large as the factory body mount bushings, there is no change in loading on the body:

Problems with lift blocks that are too small:


Are typically eliminated if a proper size block is used:


Yes, there is more leverage on the body mounts and bolts with the added height, so that is where higher strength hardware can help:

I routinely haul 500-1000 pounds of steel and other supplies in the back of my '85 as well as many hundreds of pounds of gear on the trail. I recently removed the body lift blocks to inspect the condition of the cab floor and saw no sgns or any damage or wear. Factory paint was still intact and undamaged.

Good to know. And it seems as though 4crawler will be having my repeat buisness...once I decide to pony up for bigger tires
