Outer Limits 4x4 Board

air bumps. if we are working on the front of a solid axle rig with 7 inches of up travel it is best to have the bump come in contact with the axle in the last 2ish'' of travel. the idea of the bump is to slow the axle before impact with the frame. the bump should bottom out just before the shock. so ...

Sorry guys been a bit busy the last few months.
Lets talk about up-travel, down travel. how much shock shaft is showing at ride height. just say we are running a 14'' travel coil over. you want 7'' of shaft showing at ride height, so the shock will have 7'' of up travel and 7'' of down travel on a ...

I wrote out a big long story about up-travel, but when i pressed submit it disappeared. sorry will try later.

A bench tune on your shocks will get you 60% of the shocks available performance, unless you are bolting it to a dead stock rig that the shock guy has set up for that std rig. the minute you add spare wheels, bull bars, batteries, etc and or change the spring rate that tune is different. On a road ...

i think it would be better at this stage to discuss the basic before i answer all the individual questions, but keep them coming so that i can see where people are having troubles.

ok so we have so softer springs in the rig. the springs will have some preload on them at full droop. the amount of ...

springs hold the rig up. most people think that if the rig is bottoming you put a much larger spring rate in to stop the rig from bottoming. If you keep adding spring rate to your rig to stop it from bottoming you will find that when you go off road the rig rides ruff and does not flex at all. Like ...

Hi all, my name is Matt Dunk and I thought I might do a bit of tech on setting up your coil overs in your rigs. I will start of by saying what I have learned over the past few years has been a mixture of oz rigs and usa rigs. This will be a basic all round look at do's and don'ts. Remember if you ...

thanks mate i will give them a call.

looking to buy some fox coil overs in oz from a retail shop. who and where is the best place to buy from.

i run fox coilovers on my ultra 4 class 8 machine. i have had no problems with them in the time i have been running them, 2.5 years. i also do all my own tuning work. i have not seen inside a profender coilover, but if you don't set them up right in the beginning they well ride bad and give you lots ...

thanks for the invite dave, but no thanks mate, kor has everthing that i like to drive, rocks, dirt tracks,steep hills,wombat holes and distance. not into winching my bus out of a creek and up a sheer mud wall. but there is a place for this. hence winch events.

been to tuff truck, been to winch events, been to rock crawling, been to this, been to that, but raced at KOR and loved it.
pulling a car around with a piece of string is not my thing, driving between orange witches hat is not my thing, but if we were all the same, it would be a boring old world ...

I have received some parts, shocks, coils, bypasses, bumps, rear axles, ctm's and one transfer adaptor. Still waiting some more transfer parts. Should be about a week. While I have been waiting I started building my wifes buggy and its 80% done. I'll start back on the Ultra4 car next weekend. As I ...

this will be funny can't wait to see the spring lbs you end up with :?

Why would I end up with huge springs, during normal use the coilovers won't be at any more of an angle than any other linked setup, even at full travel there's won't be much difference to your normal 3/4 Link setup
Yes the ...

How in the hell do you think this thing will ever work with the extractors mounted up side down is it to keep heat away from the sump.Will you be competing in the next tuff truck.
Why are the rear shocks mounted on the lower arms won't the arms bend and if you have 16'' shocks mounted like that ...

Thanks Bru21 for the offer but I have a pallet on the way with more goodies. I don’t think I will run a 40 series body, not the shape I’m after.

Tuf045, Zukizzy is on the money with bush’s on the heims and coil over placement.

Napsta, The frame should be OK for offroad racing rules. No coolant ...

Jake, sounds good mate!
If your on the limiter in low range, put it in high and hit some jumps and bumps on the limiter, see how you go.
That is what I would do. I look forward to your reply

Smitty, Did not have any plans for yoke protection, but it sounds like a good idea. I'll see how I go for ...

More Photo's will post some more next week.

Should be racing at King of the Rim.

I would not run dana 60 centres

Sexy as.

Can any one tell me what sort of costs are involved and which suppliers are best for getting a set of built Dana60's/Spider9's/Corporate14bolt?

What sort of options and components would you use for each manufacturers axle end to end and at what cost?

I've been following the Ultra4 scene ...

Still waiting on a few parts from the US, rear axles and CTM's and bypass - but their on their way. Mocking it up with patrol diffs just in case there is a hold up on the parts from the US.
