And although TCS doesn't make a rear shock for a blaster, you'd have a pretty good setup buying a used 01 660 shock, and getting TCS to revalve that for the blaster. Less money and a very good performing shock.
TCS does an awesome job at revalving stock shocks, that's why they've been backed up so much lately. I've been waiting since the middle of november for my front shocks and still don't have them. Up until the beginning of january they were only doing revalves, not building any new shocks. Then when they started building new ones again they used up most of their part inventory and that's why i'm still waiting. I can't wait to get mine though, it sucks so much to be rolling around on stock shocks from a suzuki eiger 4x4, but that's the only thing I have right now that work with my a-arms, stock ones are too long.
