BrianG · 05:48 PM

With jumps that high/far, there is a LOT of stress on those bulkheads. I'd be surprised if you DIDN'T break anything.

What's probably happening is that the shocks are bottoming out and there is nowhere else for all that force to go, so it puts a lot of stress on the rocker arm pivot point and breaking it. I'm surprised the shock shafts are handling it though - I would have expected those to break as well/instead.

If far jumping is what you are doing mostly, I would try the stiffest springs you can with a lot of preload. The idea is the make sure the shocks still have room to travel. Maybe even use the LT rockers instead to give a little more shock travel. May help to set things up so the chassis bottoms out before the shocks do...

The only time I broke a bulkhead is when I ran into a basketball pole ~40mph. I've done plenty of cartwheels with no bulkhead damage, but then again, I never tried jumps that big.
