Hey everyone, I just bought a 1999 Mike bos chassis jr dragster. I’m new to this whole thing and the car is completely gutted except for the steering shaft. I was looking for any help I can get on what I should get to put on it (13.90). It seems like a lot of small things. If anyone knows of any starter kits that come with a bunch of stuff that’d be awesome if not then any help would be greatly appreciated ..read more

Hi Nick, I’m Jeremy Boskovich from Sydney Australia, we have currently stepped back my sons 3 1/2 McGee to a 3 1/4 , since doing this we have run into a really bad stumbling which eventually clears up before 60ft. The thing is it only does this with the shockwave primary and secondary clutch. When I put our polar quick shift  primary and secondary it doesn’t do it.

It’s like a manual car taking off in second or third gear. I’m quite ..read more
