77 M880 Lift Question

[cajuncustom]

i recently bought a 77 m880 and im currently lifting it 8 inchs and putting a set of hummer rims and tires , the problem i am having is U bolts it seems no one sells them without a lift kitt or if they do they dont have the time to deal with you , the only information i could get was from a sky jacker lift kitt was the sizes , i would love some help with custom u bolts


this was the skyjacker info

check with BDS suspension, I'd be surprised if they wouldn't sell the bolts. Otherwise, maybe direct to your local off-road shop?

Thank you i shot them a email , ill take any leads i can get it seems thats the only thing holding me back at the moment

Most all truck spring shops can make U bolts, In my experience they cost way less than buying them prepackaged.

I did get a order going thru BDS i found the sizes on there , i did also try some spring shops in the area , i found one that was like 3 hours from us i asked if they could ship he said sure how you paying , i told him CC he is like ohh well we need someone here to sign the CC sale , lol i was floored

Bob H is right . When I re-did my springs on my 880 I went into Palmer Spring in Providence RI and they made them while I waited. About 15 Minutes.

I did get the bolts thru BDS they were quality items but would not work , not their fault , by Skyjacker dimensions they were for a 8 inch lift , but after lookin at the m880 they would never make a m880 a 8 inch lift , you cant go by those sizes , just the spring packs on a m880 alone are almost 8 inchs so you need 16 inchs at least of u bolts, i ended up getting them made local so tomorrow i can see how it will work this is how it looks with hummer wheels before the lift

have a few updated pics so far , rear end is lifted front is in the works , we leveled off the front to get the exact height looks like im at 6 foot tall myself and my nose just reach's the window sill

used my son as a tape measure

ill have to relocate the shocks or make some extensions , these skyjackers were for a 8 inch lift , i guess they were like the Ubolts measurements from canada because none of it was for a 8 inch lift , the front we arent to sure how to go about lifting it , we were thinking of some springs from a duece and a half but we use those when bobin dueces so thats a hard call

How do you get any u-joint life with the huge drive shaft angles? I would think they would run extremely hot and be prone to vibration.
Putting the axle that far down from the springs will also cause axle dislocation under load. You will need bars from the frame to the axles to keep them in place. Judging by your name it does look like you have done things like this before, so good luck and it looks nice so far. Nice acquisition, the truck looks to be in really nice condition.

 

[cajuncustom]

oh we have just started its no where close to done , the blocks have been angled to keep the proper driveshaft angles , both the drive shafts will have to be remade and balanced , mine is minor compared to some of the stuff thats done over here we will also make bars from the frame to the differentials to keep them from rolling , we have a few dueces also that are being bobbed

got the truck where i want it but it looks like we are going to have to do some more to the front , the pinon angle is correct but the front springs are tilted to far to the front might have to add longer shackles to the back of the front springs
