Bodylift: Yes, I did search first!!!

[mc dave]

About to do a 2inch bodylift on MWB Cruiser. I've read all the previous threads and chosen Ultra High Molecular Weight Polyethylene, acquired cheaply through Tonka's suggestion.

I just wanted to check on diameter. The Middy has 5 points where the body attaches to the chassis. Front and back are about 55mm diameter and middle 3 are about 75mm diameter.

I am ASSUMING that I would want to use the largest possible lift blocks in each place. Is there any reason not to put the larger diameter blocks in the middle 3 lift points?

Ta,

Dave

im not sure, but if you have the space you could use all 75mm diameter blocks, if not, in keeping whith what is as close to standard as possible, i would use both the 55mm and 75mm,

maybe the middles are larger due to the fact that you put weight in there, like people and loads and shiat, it could be one reason, help distribute the weight

I dont know about on a cruiser but on my Hilux I used the 75mm for all of my blocks exept for the front 2 which I had to use 50mm to fit because of less room around the body mount.
Use the biggest diam that will fit as it will spread the load over a wider area of the cab and reduce the likelyhood of the blocks punching through the floor.

"yes I did a search first" this is becoming more like pirate every day.. if he didn't search, the search police would be on his ass..

sorry, just hijacked your thread cause I thought it was funny

[mc dave]

Yeah... if you look at every other thread on body lifts the first reply is always "SEARCH!!!"

The mounts on the chassis are kinda concave or cup shaped so I'm limited as to how big the blocks can go.

Seems like the consensus is go as big as possible in each spot.

Thanks guys,

Dave

use as big as you can , & machine the end down to suit your concave position !!!!

I'm curious what everyone does when doing a body lift - do you remove the standard body mounts and replace with the lift blocks, or add the lift blocks under the standard body mounts?

[ORSM45]

add blocks if the rubber still ok

I'm not sure on the middy setup, but the cup shape will be the rubber support washer. Leave the standard rubber mount in position, place the lift block between the cab mount and the standard rubber isolating mount.

[mc dave]

The cup shaped bit is metal and welded to the chassis.

Its sounding like you are saying to leave the rubber bit on top of the chassis (in the metal cup) and insert the lift block between that and the body.

Right?

Thats what I did.

Yes. There will be a rubber mount that sits inside this cup with another rubber mount that sits on the underside of the chassis mount, with a steel crush tube running through the centre of them both. This system allows the body to be isolated from the chassis, with the rubber mounts held at a constant crush rate via the body bolt, down to the thickness of the crush tube. Here is a pic from a GQ, but most cabs are mounted in this way with the rubber mounts on the chassis.
