Default BENT SHOCK SHAFTS

I KEEP BENDING REAR SHOCK SHAFTS ON MY THUNDER TIGER EB-4 S2 PRO BUGGY. I THOUGHT MAYBE I WAS USING TOO THICK OF SHOCK OIL FOR BIG JUMPS(TOO MUCH PACKING UP), SO I WENT FROM 30W TO 22.5 W. STILL BENT ONE. ANY HELP IS APPRECIATED.

Trying not to sounds bad but...

Don't crash.

I really don't think it has to do with setup. You can get some rear guards.

are you saying something is coming in from behind and bending them in a crash? other than that i don't see how a crash is any more abusive than landing hard(incorrectly) from 8+ ft.

Unless they are binding and not moving smoothly I don't see how normal compression of a shock in any normal setup would bend the sharft.

Only thing I can suggest is to check your shocks after each race to make sure they are not binding and flush dirt out of the o-rings with shock oil. To do this put oil on the shaft then compress the shock driving the oil in to the o-ring. This will flush dirt out.

Also one common mistake is to over tighten the nut on the shock tower. This will cause the shock to bind. The nut should be a self locking nut and loose allowing the shock to pivot freely.

Its an 8+ pound buggy with toothpicks for shockshafts. Try to get some different shocks that have 3.5 mm shock shafts.

Thunder tiger kinda went skimpy in the durability department on that buggy.

I guess the other cause could be toothpick shafts. Honestly I don't know much about this particular kit.

I THINK 3MM IS A LITTLE BIGGER THAN A TOOTHPICK. I BELIEVE IT MAY BE OVERTORQUING OF THE TOP NUT AS MENTIONED ABOVE.
