Outer Limits 4x4 Board

Hi all I own a p38 range rover and wondering if anyone has had much to do with lockers in the full time 4wds.

ive been talking to many a 4wd shop and they say the best way to go is arb air lockers and they dont think lock rite are the way to go for full time 4wds or any 4wd due to the way they engage.

they seem to breaking things is what they say what do all of you think? are they saying this to get more money out of me or are they in the back pockets of arb.

i would like to hear from people using both types of diff locks tell me your storys.
Cheers

IMO Selectable lockers are MUCH better than auto-lockers.

There are more options besides ARB. Maxi-Drive and Macnamara are both (IMO) superior to the ARB, AND you get upgraded axles, which you will need to buy with the ARB anyway.

I have a maxi-drive myself, fitted it myself about 6 years ago, it has always worked perfectly and I am 100% happy.

1: Jacmac or Maxi drive. both come with axles.

2: detroit locker rear and trutrac front

3: trutrac front and rear

so you think trutrac F&R ? have you seen this working.
and i just rang jacmac and the guy on the phone was rude he talked like i should of known his locking diffs and i was a tosser for not knowing then told me to look at his web site and hung up the phone strange little man.

so i suppose the next one i will talk to will be maxi drive and see what they are worth

Welcome to the world of Jacmac He is hard to deal with but makes a really good product. search around on here for more info so you know exactly what you want and then try him again.
customer service - 1
quality of product - 10.

Or try Maxi Drive, you will get much much better customer service there.

The difference in there lockers are one is vacuum operated and the other is air operated.
Good luck

yes ive been in contact with him many a time hes a real nice guy to chat to well worth giving him the time of day I too would recommend him for rr p38 parts

I have tru-tracs front and rear in a disco. No problems except you need to keep opposite side tyre pressures equal for on highway (otherwise does not track straight).

Not as good as selectable lockers. But they are good for what I want from the disco.

I have ARB lockers in a rangie and manual lockers in the bushie (neither vehicle have rover axles/diffs).

I agree with the above comments on maxi and jacmac lockers.

so it sounds like tru-tracs front and rear are the way to go anyone know what they are worth ?
my RR has got traction control that seems to work well now i fixed the abs pump that cost $6000 i will never c the money in the parts for cars but what ever you still have to pay it
anyone got any video of all the different lockers working they can post up here for me to have a look at

ARB, Jac Mac or MD selectable are the best.

PS can someone in Melbourne please vist JM one day and tell them about customer relations - or poke Jeff in the eye with a stick:)

Another option is to go with ARB lockers F&R. I can supply you with Longfield CV's and axles that will ensure the front axles & CV's won't break.
The ARB locker can get fitted anywhere and you can fit the axles and CV's yourself or get your local workshop to do it for you. We ran them on Mike Smiths Range Rover at the Ateco and couldn't break them.

So apart from the above the TT has no adverse \effects in the front?
I was thinking of fitting a front TT to my 110, as it is mainly a touring vehicle.

Tru-tracs are excellent with traction control. Traction control overcomes the weakness of tru-tracs and tru-tracs improve the performance of traction control. They also replace the weak rover diff centre.

The importer Locked Drive Systems http://www.locked-drive.com.au is cheaper than dealers such as Opp Lock. They are considerably less than selectable lockers.

No other adverse affects in my experience.

If not wanting to go full on extreme then I would look at 2 options.

Detroit in the rear and trutrac in the front.

with Traction control I would go wit TT both front and rear .

either of these 2 set ups wil get you 99% of anywhere you want to go and probaly 110 %.

both set ups just work.
both give differential action when required even off road ware you may want to turn both set ups will work and work well.

What sort of money are you asking for longfields, and are they as good as maxi drive or jacmacs reputation?
I'm trying to fing a good way to strengthen the front without it costing one of my testicles.

Longfields can be broken. Nothing is unbreakable.

What you are suggesting is a good option, though.

hmm. ihave have arb's front and rear, jacmac axles and heat treated hilux c.v's (i know i'm sorry) made by haultech, a couple of years of abuse now, and so far can't hurt them, on 35's, etc.

although i had aftermarket county c.v's at first and they only lasted a couple of months!

well now i really dont know what to do ?

It sound a bit like everyone is really saying TT and Rear D locker or TT F & R
I know air activated lockers are maybe the way but i just justify the money for the amount of 4wding i do now.

6 years ago i would of spent every cent i had but, children has stopped that and a well the handbreak as also.

And i can see her point because the rangie is our only family car, i have to go easy on the old girl.

So now not sounding like im trying to be cheap has anyone got any idea what TT would cost F&R.

The traction control works well and love it but, sometime you just feel it need that bit more or maybe its the older 4wder coming out in me.

Also has anyone got an idea of the life of a TT centre do they wear out ?

"AND" shame on you using toyota parts in your landie its diseased now keep it away for other landies we all dont want to catch it

yeah yeah i know, but they haven't failed yet!!

another option is haultechs traction control, nice and easy on your running gear, and effective, and dont think it costs too much?

Bushy, by the look of your tyres, how about a more aggressive set for offroading than those crappy road tyres you run.
This and traction control will make a massive difference

I haven't looked at your tyres yet, but, I think this is the most constructive bit of advice yet.

yeah next time i buy tyres I will be but i cant go full mud because its a family car as well will do the 60/40 thing with the tyres when i buy next

I'd be loking in that direction before even thinking about lockers. Drive it with muds for a few months and seehow you go.
