Lifting a Bobbed Deuce

[USArmyMedic07]

I don't think the perch setup will be my weak point. If anything, it'll be that I'm only using One bolt to hold on each hanger.

you can get lift springs made. i have 6" lift springs in the front and 6" blocks welded onto the rear. the front rides great and the rear is firmly planted with zero axle wrap.

cavemantrucks provided the springs from a local spring shop.

Dang, now thats what I like to hear!!! I'll call my local spring shop today and see if they can make me a pair for the front. I never though lift perches were the best way to go, but I know stack frames and whatnot isn't the best thing either. Lift springs would be my first choice!!! I've even got an extra set of trailer springs I could use.

THANKS!!!

Any pictures of the front springs? I like the setup you have in the rear. I'm not a fan of block anywhere, but those trac-bars make it worth it.

Any pictures of the front springs? ...

i will try to remember to take a couple pics tonight/tomorrow.

 

[mudguppy]

actually, i have a few pics from the other week that show the front springs.

(and, yes, i'm still waiting on my alternator... )

Looking good Mudguppy!

 

[Jakob]

Those are re-arched stock springs or custom work?

 

[mudguppy]

to be honest, i don't know. i think they're custom, but Jim is the one that had them built.

 

[Jakob]

Don't mind me if I'm asking too many questions. It's my own way of showing that I am impressed with someone's work. I really like the setup you have on your truck and it's what I want to do with mine. Only I'm wanting to do a full length 4x4, instead of bobbing it.

 

[mudguppy]

no worries, Jakob. i just really don't know if they are re-arched or custom packs. i know that they ride quite well. i do wish i would have opted for 8" rather than the 6". i recently gained another 1", but i still plan to trim the fenders some. not for street, but for off-road.

Did you make a print when you made your brackets for you lift

No, not a print. When I drew it, I laid it out on heavy card stock and cut out the shape. Then traced it on the 3/8" plate, and sheared it on the lines.

I'm curious, is there any need for concern about the rear blocks parallelograming sideways?

 

[mudguppy]

if they weren't welded, i'd say yes.

Is it possible that the welds could hold but the u-bolts or lifting blocks fail? Or a section of axle tube tear out? Even under articulation there is probably significant sideways force. In a slide where you then hit something hard, could the whole thing buckle?

I wonder if crosswise links or triangular gussets parallel to the axle would reduce the chance of that happening.

no. u-bolts are much more flexible than welds. the welds would crack and fail long before the u-bolts. and the blocks are constructed out of very thick plate - i don't see these failing before the previous two components.

sure, anything is possible. there is plenty of room there and gussets could easily be added to increase the rigidity of the blocks from latitudinal forces.

with the relatively light weight of a bobber rear end, i think this sort of failure is extremely unlikely. if this were to be installed on a truck expected to see load, i would consider additional support on the rear blocks as mandatory. better yet, i'd probably go with full springs or air bags.

Or, back half it? <kidding>

Thanks for not taking my comments personally. I understand your points, and since you have it right there in front of you, you are in a far better position to decide what it needs. If it were my bobber (not too far in the future, hopefully), in a case like this I would probably add a triangular gusset from the blocks towards the outboard side for my own piece of mind.

I don't think you have near enough tool boxes.

Tool boxes are like shop space never can have enough

What are your feelings about stock brakes now that you've driven the beast?

I wounder how had it would be to do a 5ton
