Accidentally sent that early but a linkage won't work either. Second swingarm is also a + 8 arched ladder bar it' was on a sand dragon chassis and had a no link stock shock setup. When it's on a stock chassis it won't work either are both these swingarms for aftermarket chassis setups only? I guess u could run a strut but I don't drag only. do I have to move my shock location on the frame like some chassis have done to run these arms?
