I got a similar deal on ebay a couple months back $570 incl very fast shipping. I had the front locker 168PL22 and an ARB CKMA12 ($250 incl shipping) installed for $785. Everything the shop needed to perform the install parts wise was included between the locker and compressor. Except one VERY important thing. My TJM locker required a special pipe tap, that was pretty hard to find in the US. But rather common in Great Britain and India, maybe some other places. I think it was a BPT 19x1/4, if I remember correctly.
The locker and compressor combo have been great. I use the compressor all the time, not only to air up, but around the house for bike tires, basketballs etc. Very handy. The locker operates seamlessly. Flip the switch on and it engages almost instantly, flip it off and it disengages within a blink as long as the locker is not under load. I had it sitting on the counter in my garage for a week before the install, wow, what a nice piece! The construction quality is exact. After you see and feel the fragile OEM 2 or 4 pinion carrier and you see this, you will feel much more confident about the already amazing reliability of these vehicles.
Two days before I found the TJM locker, I was ready to purchase a Harrop E-locker, which I believe to be an awesome locker. Problem is that it was going to be about $2400 all in incl shipping and installation of the locker. I would still need a compressor for airing up (and installation of the compressor). I saved myself perhaps $1200, if you count the compressor. In researching all the few front locker options available for the LC100, I found a lot of interesting info. Most interesting of all is that TJM lockers have probably been around longer than the industry stalwart ARB air lockers. How so? TJM actually bought another company named after Jack McNamara . By talking via email with a few vendors in Australia, some told me that ARB lockers were actually a copy or were "inspired by" early versions of the "Jack Mac" locker (as they called it). If you speak with people down under about the TJM and "Jack Mac" lockers, they are very well regarded. As a matter of fact, I could not find even one first hand account of one of these lockers actually breaking. This was over a couple weeks of somewhat casual research and a few personal messages.
Very cool. I remember reading somewhere that the pro lockers had been around for awhile.
I'm getting my front and rear lockers installed for $1060 mid January. I'll have to install the compressor myself to save $400 but it seems pretty straight forward. Would you mind confirming what the part you needed was? I'd like to relay that info to the shop I'll be using.
