Arb diff lock or detroit locker?

[Mr Alford]

im looking at both and on a budget, i was wondering who has either im looking for just the rear at the moment as i cant afford both the detroit locker is around £350 and i can fit it myself i have heard is good offroad and thats all im interested in i dont care about on road as i hardly ever use it onroad

secondly the arb i have heard great reports about it but then the cost goes up and it has to be fitted by someone else correct?


comments from anyone who has either

i am swayed towards the detroit due to cost

dont like the sound of the running gear with lockers in. locker would make ur truck almost unstoppable but halfshafts would break easilys and a 3.54 diff would not be long after.

fiddle brakes would be a cheap as to locking a spinning wheel on the back.

as far as a locker goes id have to go for arb ever time i think.

do you have either of them?

[mentalmoshio sophs V8i]

i almost brought arbs a few months back , 2 lockers are the same price as winches front and back . so u will be stuck even with lockers but not winches to hand

as for driving with welded up diffs or truetrac effect then great for straight bits , but poor turning and mega stress on standard running gear

( oh that was on 8000 series tractor ruts in mid winter)

gr8 truck so far mr a think carefully for future mods

im now running over 3oo bhp ( im sure the gearbox gets worst every day ) so light attack off road all the time

both my diffs are on the way out they have as much slack as a 50 year olds snatch so u rekon i shud get 2 second hand diffs for £70 and buy a superwinch epi9.5? cos i can get my hands on one for around 430

IIRC fiddle brakes are illegal on road anyway? Don't think you really want to have to trailer it everywhere and stick to private sites!

fiddle breaks are not road legal as you have to have the fiddle breaks plumbed into the back and the foot petal does the front......I'm not going there!
as for lockers, i would go with the propper locker, the viscous units will never be as good as a true locking diff. sorry to say i think stev-o needs to think about what he is saying.....again! it all depends on the application both are as good as each other if used correctly. if you say that your diffs are on there way out then another alternative is diff pegging from ashcroft. they uprate all the materials and peg the crown wheel which improves the performance of the unit and also makes it last longer. also if you are looking at difflocks you will need uprated shafts, with all lockers in there is a possibility that only 1 wheel has traction therefor all power/torque is sent through that wheel.......causing havoc with shafts. ARB seem to be the thing people go for but i have seen a few posts here and there about how [!Expletive Deleted!] they are and the mcnamara ones are better.....don't know if its true its just what i hear(*read*) maxidrive i believe are doing good deals on shafts and locker kits. i hear there also pretty straightforward to fit. if i were you i would Peg the diffs and invest in a winch.....doesn't have to be a good one at the moment because when the time comes for you to need a good one( if you do need a good one ignore what i just said) then you can put the cheaper one in the back. hope that has helped.....i am full of more useless information if needed.

Not sure about the legality side of it but the typical plumbing for fiddle brakes is to have all 4 brakes worked of the foot peddle as per normal but with the brake line to the rear going to the fiddle brake master cylinders (MC) and 2 seperate brake lines from the fiddle brake MC to the brakes. During normal braking the the fiddle barke MCs just act as a T piece allowing fluid to flow freely to the brakes (like the T piece above the rear diff on land rovers). When a fiddle brake is operated, the fiddle brake MC inlet from the main MC is closed off, traping the fluid and as you continue to pull on the leaver, preasurising the trapped fluid which works the individual brake. Release the fiddle brake, the inlet valve opens again and the brake is reconnected to the foot peddal.

ah i was told that you couldn't do that because all it would do is push the fluid into the reservoir

top facts again boss learning alot from u  :)

what ever drugs you are on must be good

there is no waaaaaaaay you can have 300 ponies, :^o

[mentalmoshio sophs V8i]

haha mike its me making the deeper hole ever time it sinks by flooring it.  :lol: :lol: :lol:

as for high does ep90 count  :lol: :lol: :lol: :lol: god that stuff stinks

[clbarclay]

That was the way I've seen fiddle brakes pumbed. Stopping the fluid flowing back to the resevoir with fiddle breaks should be no more difficult than preventing it flowing back to the reservoir with a normal master cylinder.

 :off topic: do tell what you have done to achieve 300bhp. i would love to know! also, its not all about ultimate power :off topic:

I'd love to know too, as from what I've read to get to (and indeed past) 300bhp with a rover V8 you pretty much need a hand-built engine!

The things you find out when researching if you could get 500bhp from a 5l Rover V8 with twin turbos...  :lol:

[clbarclay]

Try reading the bit in brakets in his sig, might give you a clue

ha! i belive it when i see it!

[boss]

nice try to throw us off, its not a tvr its a rover v8 tvr used it and called it the 350i but its the same engine! you ass!
still awaiting info on how 300BHP is achieved!

[mentalmoshio sophs V8i]

high pressure fuel pump, kn filter , twin core leads , stage  2 chipped , high rev camshaft, hd clutch list goes on and on  and 240 to start with.

running on standard brakes and cooling system  :| as for top whack eh 120+

5l tvr has 325bhp to start with they start from 4 k

then you will have at most 260 ish  :lol:

i smell a large amount of BS

Ps i run ARB lockers as far as im concered they are the bubles

oh dear oh dear another boy racer turned offroader why do u need 300bhp?

i bet ur car looks at a puddle and conks out what a fool

[davidlandy]

go for ARB - they are much better than detroit lockers. You can switch them in and out. I wouldnt compare a locker to having a winch either as they both do very different things. A locker will get you further into trouble and  the winch is there to get you out!

Mr 300bhp V8 man, I am a little sceptical about what you say, I know that they have come along way but I do fail to see how you can pop down Halfords and simply buy the bits to give you 300bhp - why dont you prove it and post the scan of your rolling road print out?     

[mentalmoshio sophs V8i]

 :roll: :roll: isnt the new supercharged 4.2 v8 gonna be 500 hp and electronic stuff as well  :-k times have move on from oiler burner of the 60s   :twisted:

seeing some advanced hybrid builds coming with hdc / tc / esc and other aids too.

besides underdrive units our here now .


lockers work if a wheel touchs the ground to make progress next steep long travel indenpendant suspension  came before locker  :-k

Still cant see how you got 300 ponies out of a 3.5 v8?!?!?

I can remember years ago seeing a e30 bmw with a 4.0 rover v8 with quad 48mm throttle bodies, twin turbos, forged low comp pistons and a stand alone ecu and that made 400 bhp so im at a loss as to how you only have 100 bhp less?

My 3.9 v8 is meant to have 180bhp but i dare bet it puts out less than 150bhp!

Also you have a high rev cam?! So you have plenty of top end power which is brilliant for low rpm off roading!

I think you need to chop your disco in for a saxo 1.1 or something  :lol:

Anyway back on track, i would say arb's all day long! A friend runs these with 35" simex's and standard halfshafts and cv's and they run fine! Its not what you've got (300bhp etc!) its how you use it!

120mph in a lifted disco on standard brakes? Dave, for this reason if no other, I'm glad your miles away from the roads me and my family use pal. I've never been past 85 in mine and then about once.

85 that 3rd gear  :lol: :lol: :lol: for me and yes drilled and vented brakes our on the list to do

[Gav_T]

Seriously have a word with yourself pal!

120mph in a disco?Even with ,ahem, 300bhp i think you would be pushing it but seeing as you have got the worlds biggest roof rack on it, along with every other bit of tat possibly nailed on i reckon it wouldnt even make a ton.

Gavin.

[insa-disco]

my 200tdi does 62 flat out by road angel lmao ( speedo cable snapped after 2 inch body lift) but its great for off roading as im only a beginner, my mate has a arb locker in his disco and says its great ( untill he pops it again ) the detriot locker is just basically a limited slip diff isnt it? as one wheel spins it locks the other to it?

[Steve ray]

Meanwhile, back on thread .............  ;)

ARB's are probably the better option (plus you get onboard compressor - great for reinflation of tyres). They are switchable, so YOU decide when they're on or off. They do seem to be "high maintenance" though and often require attention and they are VERY expensive!

Detroits are "fit n forget" in terms of maintenance - just need to adjust driving style a little and they're a lot cheaper!!

I run a Detroit in the rear (open diff in front axle) - this coupled with good articulation gets me (almost) everywhere I need to go and my Disco gets used and abused almost every weekend. The only downside to a Detroit, is trying to make low speed turns in very slippery mud, it has a tendancy to 'push on' rather than let you make the turn.

Hopefully, that's helped with some of the pro's & con's for you .........
