Question Hot Racing Lock Differential Spool

Hey guyz, has anyone tried a Lock Differential Spool from Hot Racing on a Slash, and if so, what do you think about it? Do you think you will get more performance out of this item?

I would run the FLM diff for true performance.

I ran a stock locked diff (basically the same thing) in my VXL powered Slash for two battery packs...broke two driveshafts in that amount of time mashing the throttle coming out of turns.

Spools aren't for everyone, it depends on your driving style. I like running a spool because I can throw the rear end around a lot more, and it makes sliding through corners a lot easier. Trying to hang the back out with a differential is tough because power generally wants to go to the inside tire and straighten the truck out, but tromp on the throttle with a spool and both tires spin in unison. From there it's standard-issue dirt racing, feathering the throttle and countersteering to maintain corner speed.

But diffs have their advantages too, especially on slow, tight, hard packed indoor tracks. In situations like that a spooled truck won't have enough room and maybe not enough power to break the rear end loose, where a diff truck can just slow down and hug the end of the pipe. And like Cheatin pointed out, spools are typically are a lot harder on driveshafts than diffs.

Just my $0.02 on rear gears in general

If you like popping wheelies... then yes. Most of the guys I know that are just bashing, have switch back to the stock open diff because they are tired of breaking shafts and cvds.

I've found a limited slip works best for me. And its very cheap to do. If u do a search on traxxas.com's forum u can find a gew threads on how to do it with the stock diff. With mine I can slide like a locked diff and no broken driveshats yet. Just more food for thought.

I did a search for limited slip on the Traxxas forum, being a member, and found this for you:

The rear diff I use ofna diff lock lube, makes it act like a limited slip.

Rear end still squats on take off but I put some rubber o-rings on the shock shafts so it doesn't bottom out anymore.

Couldn't find any tutorials on installation though... and I wouldn't recommend for hard surface from the posts... Hope it helps!

Well here's a link to one of the treads that helped me a lot.

But if you do a "diff" search you'll find more.
