Relocation Brackets

Been running UMI rear control arms, control arm braces and relocation brackets. Broke the pass side relocation bracket today...is there a better solution to either get better ones or get around using them?

The only two options that I know of for you would be the weld-in UMI lift bars....

https://www.umiperformance.com/home/...et-up-weld-in/

or the weld-in relocation brackets......

https://www.umiperformance.com/home/...ckets-weld-in/

Did you break the bracket while launching at the drag strip? Or did it break during street driving?....(pot hole?)???

Took it out in the country to my test spot...made a pass and went home. Starting to turn in the driveway it broke. I don’t street drive it much.

Although a bit spendy I think I'd prefer this.

Re: Relocation Brackets

You might want to contact UMI they are good people and might sent you another bracket.

Then put a couple of welds attaching the bracket to the rear-end housings

Backordered....I've seen those before, only ever used these UMI's. These lower brackets seemed kinda hokey, but have worked good. Aside from previously breaking a shock bolt at the finish line and this bracket breaking that is.

I sent an email last nite, see what happens. I should have tacked them on, wasn't sure about doing that. Seems like a good idea.

Re: Relocation Brackets

If you weld them don't just tack them weld them good.

I've run the same Art Morrison no-hop bars since 1999-2000 timeframe.

Had them off last year for rear end rebuild and all was well.

does your drag class allow only bolt on suspension items; not weld on??
IIRC some of the classes allow these parts but; not welded to the axle
the ''southside machine'' brackets i've been running were welded in;
after i noticed that they were moving around some, when only bolted in.
no issues since they were welded to rear axle

Reading the ad, I already have adjustable upper arms to set the pinion, what else would these offer?

No I just bracket race and can run whatever, just no throttle stops or delay boxes.

Not sure if having these welded in would have stopped it from breaking.

Re: Relocation Brackets

Looking at summit it appears that UMI 4010 only has two different holes, not three like in previous post....

Must be an old picture. The UMI site’s pics show three holes like mine.

The difference would be those mounting brackets having the multiple holes for instant center adjustments. Ofcourse they would require welding too, and personally, I'd rather weld-in the UMI brackets for the lower arms. Either way would get the job done. However, I'd try to find out if you can buy the brackets only without the upper arms since you already have adjustable upper arms. I'd also want to know if those brackets are thicker than the UMI lower brackets are. IMO 1/4" thickness would be better than 3/16".

But I would write or call UMI to make them aware of this problem. If they replace them for free, you can either request that they give you the weld-in ones instead, (since they're less expensive anyway, and don't come painted) or you can just take the bolt-in ones, knock the paint off the edges, and weld them in. Tell them you're from the Chevelles.com board so they know that your negative experience with their product might very well be made public. Perhaps they will consider upgrading their product to a 1/4" thickness.

Yes it is an old pic. UMI used to make them with two holes.
