I think that rather than on relying on the finicky TCC system and always worrying in the back of my mind about the flimsy diffs and axles, i would like to just bite the bullet and get selectable lockers and upgraded shafts.

The KAM electric lockers have really caught my eye but there doesn't seem to be a lot of first hand reviews on them. I know that a lot of Toyota's came/come with them from the factory and with good results but i am under the impression that they are somewhat weaker than say an ARB pneumatic unit. given their simplicity and the fact that this vehicle will never see tires bigger than 35's (in all reality probably never bigger than 32's) i would assume that they would be more than adequate relative to the factory units.

generally they peak my interest because there is nothing in the system that can effect their smooth operation. No air tanks, no compressor, no lines. Just a wire, which in the worst case scenario could be repaired on the trail.

 

I've looked at them also and always ran arb's on my jeeps but when I do my suspension upgrades on my disco, I'm going Ashcroft. It's a pneumatic locker but unlike arb it rotates in place so there is no risk of the line internally failing. I've had buddies with electric lockers and the right limb will break it. I'd call around to so off road shops locally and find out their opinions/advice on them.

 

No. Ashcroft.

 

sorry i don't follow. you mean they've broken them on a good sized tree root?

 

I know the guys at KAM near Godalming, they are a decent bunch but IMO I would go for the Ashcroft system as it doesn't involve electrics and Ashcroft have been around a long time, in fact, so have KAM.

 

see that's where im having problems deciding. because the Ashcroft does in fact involve electrics because it requires an on board compressor and regulator. This is on top of air lines. so two systems that could fault. Im confident in my wiring, routing, and cable protection techniques....there's not much to it with common sense, but why add complexity if its unnecessary?

Whereas the KAM only has electrics. just two wires in the whole system and a switch. literally nothing can go wrong except for the wire being severed, in which case an extra 10ft of wire and a few crimp connections in the glove box in case of such is all that would be needed for a repair. something that would take 10 minutes if it ever occurred at all.

this is all a mute point though if the KAM is significantly weaker than the ashcroft.

 

If you are comfortable installing the KAM system I would go with it, there is very little to choose between the Ashcroft and KAM lockers. As already stated, these guys are not cowboys, they are a decent bunch of guys who have worked very hard over many years, around 25 years TMK, building up a reputable prize winning business and if there transpires to be an issue they will help you whatever their cost.

Doesn't the KAM require cutting and welding on the axle housings to install?

 

No, they are a drop in unit now.
