Upgrade kit, 2016 gears and chain and it includes the new tensioner. Borg Warner stuff, much better than the 2012-2015 stuff. I've asked but still haven't heard of a 16 breaking the chain.. Yes it's 13 wide, but still much stronger than the old 15 wide. At a 1/4 the price of the next step, Taylor stuff which is top notch no doubt.
Here is the part numbers for 15 wide Borg Warner chain and gears, was told I could get em as exported sleds had the wider chain and gears. I ended up getting the 13 wide kit cause this would have takin longer than I wanted to wait.
