Thread: Best Rear Diff Lock for Puma 110

SWMBO is enthusiastic to get me a rear locker for the 130. I thought I'd update this thread with my research and ask for opinions on my thoughts.

Firstly, my requirements:

Touring and the occasional challenging trip where traction aids are the difference between defending the Land Rover name among those who prefer Japanese whitegoods. I cannot think of a time where I have not been able to be recovered by someone else in the convoy or by winching myself out. My 130 is mostly a farm vehicle where it gets to do all manner of tasks, not usually related to 4wd but is also our touring vehicle. A picture that I showed to the Land Rover experience guys at Solihull probably explains it best. The location is on Macfarlaines/Cowombat track on the last climb towards Limestone road. My D3 made it up here easily a couple of times but I couldn't proceed in the Defender.

So far my research is as follows

ARB air locker $1635 Fitted
TJM Pro locker $1499 - Does not specify fitted or not
Ashcroft ATB $721 inc GST - no freight no Fitting (Paddocks)
Ashcroft Air Locker $1133 inc GST- no fitting ( Paddocks)
Harrop Elocker $1728 no fitting Harrop Aust How do these blokes sell these???

My preference is for a manually controlled unit and probably for the Eaton but its pretty hard to justify the additional cost Thoughts?

Ashcroft or TJM for a full locker.
They are the best/most robust/reliable designs IMO.

ATB if you want set and forget and don't lift wheels, unless the TC is better than the TD5 versions?
With the ATB you just need to be careful what oil you run for maximum traction.

ATB.

I would use the ARB, Prolocker or the Ashcroft.

Personally I would choose the ARB Airlocker because it is Australian, the support is excellent, parts are easy and all of the necessary components intergrate perfectly as a one stop package. There is a lot of talk about the ARB design during the update not being as good as the older ones due to less depth in the locking dog, personally I don't think its a problem, its an issue that has been talked up by the massive tyred V8 comp guys - they seem to work in every other comp car still, go figure. I think its a pretty high quality unit, they are strong, they're proven in competition, parts are available from your dealers down the road, and they will fix anything under warranty without a problem.

The Ashcroft is also a good unit, high quality, proven in comps. If you want the part then you will have to import and if there is a prob you will have to send it back. Ashcroft don't have a good reputation for their support.

Prolocker is also a good unit, high quality, design has been taken from Jack McNamara diff's in Melbourne and has been the benchmark for a long time in airlocker design. Fortunately you don't have to deal with Jeff there to get one of these lockers. I'm not sure, but I suspect TJM now manufactures these and I'm not sure where these are made. If the quality is the same as what JacMac were doing, these should be good.

ATB - its not a locking diff. For the same money you will get more positive drive from a locker and the freedom and stability of an open diff on the road.

ELocker..... well, see this video from Stefan , a highly experienced operator and enthusiast. Very interesting, you wouldn't go there.

As Slunnie mentioned a TBD - ATB is not a locker till a bit of work
