How much will these take before giving out? I have my chassis built to the stage where I am ready to see to the rear end, but I can't decide on running a Live rear (linked) or a sierra diff setup with trailing arms.

Any input appreciated.

Should take 180 - 200 lbs.ft I reckon. If you match it to a type 9 gearbox the gearbox would probably give up first.

What gearbox and live axle are you thinking about using?

MT75 and mk1 capri 3 ltr baby atlas (well like by the drag boys for their strength)
