Anybody hear of it,

I ran the first mud bog last night in the 49, actually it was a side x side drag race, but either way I got to test it out,
the first to runs were time trials, the first one I tried going easy but found it har to controly the throttle. so it was like trying to ride a bucking horse through the pit,
the second run was a lot better, actually got the throttle smoothed out, and acelerate through the pit, (instead of hopping through)

Then came the first round of eliminations, I was matched up against a 79 f150 with 1ton running gear, a ranger body & claiming 700+ hp, ( it was actually the 2 tone blue 79 that was it TTC last year) it now sports the ranger body since the 79 body got thrashed,
Any way, when we got the green I give it a little much off the line lifting the front end up, the truck launched into the pit & I couldn't get into the throttly smoothly, resulting in the front end popping up again, I backed out just enough to get the front end settle back down, then when I tried pulling through the rest of the pit, there was no go, I soon realized I broke somthing, after we got it out of the pit and a little inspection I found that I popped the chain in the case,
I haven't had time to pull the cover off yet, I had to be to work today & didn't get home til 2:00am,
So now the million dollar question, any body got any info on a heavy duty double roller size 60 chain,
I've found info on heavy duty single strand chain with heavier side plates, & I've also found where to buy HD double 60 roller chain, but no load statistics or other important info,
I have another chain to get the truck ready for the race next weekend, but if the HD chain is a lot better, then I would like to get it here before the next race,

 

Also a little side info for Pro, & Ivan, The yukon axles are still in one peace, & the edge coverter works great,
