Looking for Power-lok Differential advice-

Looking for a little advice here...I just picked up a pair of Power-Lok differentials for my D44's. I want to put new clutch packs in them, and found a supplier. But...they list a front kit and a rear kit. It was explained the disks were dished more on the front kit to minimize undesirable driving side-effects. I understand this to mean the front style would not lock up as easily or agressively as the rear. Sound right? So...wouldn't I want to put a rear kit in the front for better off-road performance? This is my daily driver, but I seldom use 4wd on the road, only when the snow gets real deep. And I couldn't afford ARB's, so these will have to do. Any and all advice is welcome...

Re: Looking for Power-lok Differential advice-

I got that info by calling 6 States in Portland. That's sorta what I was thinking, set both up with the "tighter" rear clutch packs. I was wondering if that would cause excess wear on the diff or steering issues in the front end. I am not as concerned about the steering issues, can't be worse than running a Quick-lock!

Any other opinions?

How often on the street are you going to drive with the hubs locked though?

Re: Looking for Power-lok Differential advice-

I wasn't concerned about pavement (don't use 4wd there [img]images/graemlins/burnout.gif[/img]) but I was a little concerned about packed trails where traction is good enough so there is no wheel spin. Being a clutch type, and being set up tight, alot more friction would be generated in the front- possibly prematurely wearing out the clutches. There is alot more wheel speed differentiation in the front axle than the rear.I guess that's one of the uses for the twin-sticks [img]images/graemlins/grin.gif[/img]!

Care to explain that one? I'll play with some numbers monday but I think there will be more difference in wheel distance traveled in the rear than the front.

Re: Looking for Power-lok Differential advice-

Retrain me if needed...that's what I'm here for! [img]images/graemlins/crazy.gif[/img]

I know the outside wheel on a turn has a greater distance to travel to complete the full turn. The rear wheels also follow suite, however to a lesser degree because they tend to cut the corner when they track through a turn. Therefore, I reasoned that , since the rear wheels cut the corner, and therefore effectively travel a lesser distance in a shallower arc, the amount of wheel speed difference would also be less at the rear.

Made sense to me...but I'm not afraid to admit if I'm wrong...

Re: Looking for Power-lok Differential advice-

But you have to compare the distance traveled DIFFERENCE between the outside front wheel to the inside front wheel and the distance traveled DIFFERENCE between the outside rear wheel to the inside rear wheel not front to rear.

Re: Looking for Power-lok Differential advice-

Randy:

You really need to call Ryan. He runs with Powerlocks and rebuilds them. My knowledge of them is limited. I know they are the best choice for a limited-slip type of traction device and very stout, unlike the Trac-loc. I have had some conversations with a 4x4 shop in my area about the inner workings and know there are several ways you can set up the clutch pack to make it loose, tight or in-between. Jeep used the Powerlock as the traction device option on rear axles that were the two-piece 10 or 19 spline with tapered shafts. When the 30 spline one-piece flanged shaft axles showed up they switched to Trac-locs. I hope you have a Powerlock that is for your 30 spline flanged 44 and not one for the other.

Re: Looking for Power-lok Differential advice-

Tim, I'm planning on giving him a call. Probably see him up at the Puyallup swap meet in March. You going?

I got lucky on the Power-Lok's. Ended up with a pair of 30 spline units that will fit my 4.56 gears.
