Power Trax or any other Locker Question

fastdrvr23 · March 25, 2004

Hey all,

I was wondering if anyone knew about the Powertrax "No-slip" system, and whether or not I need the Performance Cross Shafts for that application...

My truck has a 10-bolt, 8.5 Carrier, 30-Spline, 3.42 open rear diff... and I am wondering if the factory cross shafts will be adequate when both wheels are locked together.

I guess the brand of locker doesn't matter, just the experience with any cross shaft problems...

Thanks!

Will

You mean the axle shafts right? They should be more than strong enough, the gov lock has been in those rears for many years and those axles have proven to be strong when the wheels are locked together.

All this talk of "shafts" really makes me wonder about you, fastdrvr23.

You pheg.

I'm gonna find a country skank to whip your arse. lol

Just cause your truck can outrun mine, don't mean I take it in the pooper.

Just for that, I am not gonna let you go out with my sister anymore. LOL

Cool, thanks for the info! I was wondering if maybe the only used the Gov-locks in the 12 bolt as opposed to 10... also about the engagement of a locker, without clutches, maybe it might break them or something. Just my paranoia kickin' in, thanks again!

I just put in a no-slip on the same setup axle you mentioned. Powertrax supplies their own cross-shaft with the kit and it fits fine in the carrier. It's not notched out like the original open diff cross-shaft to clear spider gears. I'm assuming it's an automatic tranny so i figure it's more forgiving than a stick for driveline slap when the locker is disengaging & engaging.

My no-slip goes nuts on snow because I hear the action and feel it when a tire finds ground to grip. It feels like the axle is shaking like a dog s!%*ing peach pits and seems like it doesn't want to make up its mind to stay solidly locked when one tire wants to slip. I love its performance dispite the tricks it plays because it keeps me moving and there is absolutely no spinning. The thing I don't like about it is that I have a loud clunk when I shift into reverse because the saddle springs ride on the cross-shaft and the extra play on the shaft allows it to do so. Shifting in drive doesn't do that one bit and that's hard to figure out.

From all that I've heard about the strength of components here, the carrier is more vulnerable to be damaged than the cross-shaft itself.

Thanks for the insight man!

As long as the powertrax doesn't put any undue strain on the rear diff, I think I'm pretty much sold on it. The install seems to be pretty straightforward, and the benefits sound like that outweigh the few quirks that the system has... Hopefully in a few weeks, I'll have a reason to need that extra traction.

Thanks again...
