I just got new 2-speed clutch shoes for my aftershock. When I run my truck it takes like 15 min of WOT passes for it to shift and when it does the shoes slip on the shaft. After that happens my truck goes faster like it is in 2nd gear but it doesnt shift. What is the problem?

It sounds like you just need to tighten the center screws in clutch shoes, the ones with the little ball inside there.

If your Still Using the Stock Aftershock Spurs Chances are they are the Problem.........Up-grade to the LST2 Alum Hubs and Spurs and It should Shift Fine.......

Can somebody give me a link.

Will this be good for bashing and will it work?

no, those are only to add strength to the drive line, they wont help it shift. There are four losi part numbers that are on the lst2 page (losi.com)
