ive been reading around that allot of guys are buying this brace and slapping it on. My question is what is the brace for? im planning on running the backbone bumper setup. is the brace something i should invest it as well? thanks guys.

 

Steering box brace?

If so then yes. It supports the unibody around where the box bolts to.

 

If ur gonna run the detours backbone u won't need the c-rock brace!

 

Do you mean C-rock or antirock?

 

Wut is crock brace

 

98xj-jhon: the crock brace is a steel brace that stiffens the area where the steering box bolts to.

ALSO, anyone here running the detours backbone? i want to purchase it cuz' its cheaper than a full wich bumper.

 

The c-rock brace replaces the stock aluinuim steering box spacer steering box mounting area is a known weak spot on the xj frame.

 

x2 what jeepride said,, i change the gearbox and the aluminum spacer breaks,, tried taking it off a couple other xj and the same thing, keeps on breaking,

you could actually just purchase the inner plate from c-rok or get the entire repair/reinforcement kit.

where the gearbox mounts to the unibody, it is prone to crack under stress,

 

I plan on running the back bone set up, but don't have it yet! There is a wright up on it in the XJ wright up section!

 

I had the backbone on mine but I just got rid of it for my prerunner bumper. But it deff does make a diff wit that bumper I would recommend a steering box brace.
