Sled Pulling Q&A

Although I don't have interest in doing this with my truck, I've been getting some serious interest in sled pulling. I've got a few diesel mags that have run articles on pulling rigs, sled pulling events, & my personal favorite: The Shied Diesel Extravaganza. When it comes to raw power, I don't think it gets any more down to the nitty-gritty like a sled pulling rig. As interesting as these articles are, I don't have much info on the rules or classes that entail a sled pulling competition. For example: when it comes to 2.6, 2.8, 3.0, & super stock classes, I thought the numbers had something to do with the weight of the sled....like tons(), but turns out they're not. What do they stand for? & what are the rules & regs of a sled pull, if any? I'd like to get as much info as I can about sled pulling.

That clears up MUCH! The numbers make sense now comparing them to the articles I've been reading. There's one in particular I've read in the latest mag I picked up & had no idea why they were referring to the turbo with a 3.0 class. Thanks, SCUFFY!

Man, cchase! Have you competed in a sled pull?!?!? This is what I mean: they just don't give info on rules in mags. I would've never had any idea! Sled pulling in New England just isn't big & I wish it was. Some of those rules seem kinda strict, but I'm sure there's reason for 'em. Thanks for the rulebook, cchase, the time you put into it is much appreciated & has taught me even more about sled pulls!

Nice! Good luck with it, man. So, you've pulled an actual sled @ the fairgrounds? Or is it something else for practice runs? I just have no clue!

Most people I've talked to elsewhere in the country say the same thing too: try it for fun, get bit by the bug!

Yeah, that is funny! I'm sure there's some sort of reason for it...as if the engine isn't going to be louder than the exhaust! WTF!?
