Mutt lift kit

Post by SV2IPW » Thu Jul 31, 2008 3:07 am

I want to ask, how is it possible to lift 2in the front suspension system of the mutt without to change the angle of the weels?
Is it possible to put spacer to the main body of the car?
or to change the springs?

Great question...LOL

You need to add spacer plates on the bottom of the front uni-frame where the IFS mounts, I used two 1 inch steel plates per side on my 1967 Ford M151, longer coil springs should be used from a Jeep Wrangler or late model Cherokee. The IRS is easier to do on a M151 and M151A1 then a A2 the trailing arms on a A2 should be lengthened and wider tires are a must on all models. If you need more info just let me know and i can explain our mods no problem man. Hummerkiller

How do I feel???...LOL

Post by Hummerkiller » Fri Aug 01, 2008 10:33 pm

I feel like a dried out dog turd after a rain storm...LOL

Slowly going from feeling like s-h-i-t to a little better then...LOL

My vacation to Boston wiped me out thank God we flew this time...LOL

It was fun and we did some off roading down on the sand dunes of Cape Cod in the 1952 M38A1 I rebuilt for my Brother last year.

Not a bad Jeep only added a lift kit and bigger tires everything else is stock. Hell I bought the body tub for $50.00 and had the parts around here to throw it back together again. The body tub was near perfect with no rust or magor dents but completly stripped so we had to find a few parts to buy and trade but in the end it was a fun project and came out nice.

I finished up on the 1946 CJ2A I built for my Brother Geno but had a buddy trailer that Jeep up due to me not feeling well.

I modified the crap out of that rig...LOL

Chevy 350, automatic tranny, bucket seats 6 inch lift kit and Dana 30 and 35 axles as well as a set of 30 inch tires.

He paid for the parts and I did the work for free.

I am just now allowed a little shop time and it feels great to get my hands dirty again, decided to rebuild the original Dana axels off the CJ2A I mentioned above, a little work here and their then off to bed for rest.

I gained a little weight back, don't look like a skeloton anymore anyway...LOL

Still gowing my big Jew Beard and even had a few cold beers on vacation so life is good

My mutt had aluminum spacers stuck in the springs (two in each spring on opposite sides of each other and about midway up the spring). I cut them out since a couple were missing. I have no idea if they were military or a civi add on. They lifted the jeep about an 1" to 1 1/2" without any unusual characteristics.

Glad you are back HK. This place was not the same w/o you.

Sorry-

I didn't take any pictures of the spacers before I cut them out. They were about once inch aluminum blocks with groves in them for the springs to compress around.

Those Blocks are a Military issue

Post by Hummerkiller » Mon Aug 25, 2008 1:16 pm

They are known as coil blocks and used on the very earliest ofM151A2 FAV's even pre FAV for ground clearance over rocky terrain.

Knick named Lego's they were later added to larger longer coil springs on M151A2 FAV's allowing to about a 2-4 inch lift depending on how larger the spacer blocks were and how much the springs where stretched, some bolted in others like steel blocks were welded in place on the coli springs.

I had a debate about this with someone a while back who said they were never used and then someone lucky had a pictures of them installed to proove my point. I never took pictures of them either wished I had as it was a great solution to ground clearence issues on steep rocky terrain.

Any mod that was used in service or adapted for a said vehicle is 100% acceptable as stock Military issue, hence why I get into heated debates with some pro stock people, over modifications and Prototype designs.

Without the many Protypes their would not have been a stock model

What about center of gravity issues?

With the mutt up a little higher, wouldn't that increase the chances of roll over?

I'm asking because i would like to raise mine a little too.

Without mods on a M151 and M151A1 yes.

The trailing arms on a M151A2 pretty much erase the roll over issues with a M151 series Jeep.

So just to clarify on all this...

How much can be lifted on the front. By just using flat plate shims between the frame and the suspension assy. Without having to do different springs or shocks or??? Or are those twist in spring deals the way to go... (on a tangent I remember seeing these on something in the past, and since I only play with MVs :? )

How about the rear suspension?

I have a USMC A2 FAV. It has the "dual" springs in the rear. I think this should be enough lift overall (in the back). But what about another 1" or 2?? I have the large tires on there now and the back seems OK but the front is a problem as the tires rub on the latter part of the outer wheel well. I got under there and instantly thought 2" plate... longer bolts.... an hours work... then I started to worry about steering geometry. :roll:

dont forget the driveshafts either, the more you lift the more you're extending them. At some point you would need to lengthen them. Also you're changing the angles involved which at some point would effect the u-joints.

Got pics of the dual rear spring FAV setup? Id love to see the design.
