broken torque arm hey... just riped the mounting braket on the BMR torque arm on a 98 ss with boxed/re-lo LCAs and a spooled 4:10. i'll post pic.. any ideas what'll take the beating? ordered a UMI unit cause it has thicker mounting points... but i'm affraid the tubes welded tot he mount will rip apart... thought about roll cage gussets or larger pieces welded to the umi arm. any one have experiance with this? i wasted the stock unit .. bend it then tore it. the BMR is ripped and the bend on the end at the tranny is stressed and shows metal through the red powder coating or paint.. what ever it is. runs 7.5-7.60s in the 1/8 on 18s and playing around to and from work.

I have the UMI chassis mount and well, you could try one like that. If you break one of those..then you must have some serious power. However, there are people running faster and not breaking stuff. I would think that you had a loose bolt and you were shocking the mount when you launched. Or you bushing up front was wallowed out and causeing movent to "shock" it. I dont know how you broke that but didnt break your tailshaft housing.

have a local shop cut and replace the mounting bracket there with a 3/8 or 1/2 inch thick setup. . .you'll probably spend 30-50 bucks, but it'll hold better and be cheaper than buying a new one. . .

I assisted in the design, and testing of the RANDOM arm, and we saw the same problem, when run loose. More metal only prolongs the occurance, if it's loose.
The solid tube/brkt doesn't help with misalignment , either. We use 3/4" heims at the rear, to aleviate that, and to allow adjustments...

the elongated one was from nursing it home from panama city to atl with it busted. they were put on with blue lock tite and an impact and taken off with a breaker bar and the jack handle... only the top forward piece was holding it on... heh no crazy power.. tr230 cam and normal stuff. 4:10 w/ spool and nittos on the18s is what i think has killed it.. already twisted and tore a tubular LCA and had to go to boxed ones.. this was the next failure after that.
