Anyone used a McLeod RST Twin Disc dual clutch set up?

YR knows the deal.

Why am I thinking mud bogg and truck pullers use this thing?

As someone who used to truck pull, it's because we want clamping force with little to no slippage. Slippage is powerloss, and when you're seperated by fractions of inches, any slippage is the difference between podium and 10th place. But we also built the trucks to take that. A double disc is nice but man they make QUAD discs now that really clamp down with 3 TONS of force or more.

That said, I wouldn't run a double disc on a stock trans. If you're gonna run one, I suggest upgrading the input shaft in the 4speed. If they make an upgrade for it that is (honestly haven't looked but I will), if you're gonna be doing any hard core racing , spend the money and upgrade wherever possible in the transmission and for sure upgrade the rear axles. If you actually hook the rear tires, you might still break a u joint but that's easier to fix than the trans or axles.
