Outer Limits 4x4 Board

Had a search and couldn't find exactly what I wanted to know.

I'm putting a 4" suspension lift in the Mav (No bodylift) an will be running 35" BFG Muds and the 36" Centipedes sitting in my shed (If they fit). I'm going to be running drop boxes for castor correction, would it be worth fitting the radius arm spacers while I am at it?

Cheers

I don't know who's drop boxes you will be running but ours are designed to move the front diff forward about as much as you can safely go so radius arm spacers are not needed.

Would easily be able to fit 35's and prob 36's

If you haven't already got em give me a bell or msg

do drop boxes with standard bushes keep the castor angle right with a 4" lift?
and how much are they?

I have Cheezy chasing them up for me, not sure where from. Thanks for the offer though.

Ring Brian (fatassgq), i just bought a set from them (superior engineering in qld) and there the best thing ive bought, they told me everything i wanted to know, helped me out heaps freighting them to tassie too

they bolted in with no drama's, and as he said move's the diff forward too

cossie, i would say yes to that cause thats what they were made to suit and i put them in my gu with 7" front springs, 30mm coil spacers and im only running 2 degree bushes to try and make up the difference when it should really be 3 degree to get the extra and the thing drives better than standard, its great

flex great, drives great, they fit great, top quality gear in my eyes

cheers sean

they fix castor thats the main point of them. they were the main permanent type correction methon b4 droped arms came the rage and IMO are just as good with a much smaller price tag.

with a 4" lift you should have no worries with 35s, but you may need to shave a little off the gaurds with the pedes. I run pedes with a 6" lift and they fit in the rear fint ie just grab, but under flex they start to grab the bull bar and the bottom of the 1/4 panel in the front

I know the Wizard drop boxes are good for the 4", and move the diff forward as well. The BATC ones do too.

Better than plates as good as arms without the price tag.

I watched tiny at willowglenn driving over logs. The boxes would occasionally hit but it wasn't enough to hamper forward progress. Just get ready for more thuds

yup, I dont think I have ever being stoped by them

What is the castor correction for the drop boxes (degrees).

I have a 3 inch lift and want to correct the castor but do not want to use using offset bushes.

too much for 3", so you're stuck with bushes or plates.

I thought plates are suited to a 4 inch plus lift, what angle correction are they available in.

Are there any other options other than bushes.

Thanks

cut and roll your diff to suit the castor

DROP BOXES CAN BE USED FOR 3" OR 4" WITH NO WORRIES. I RECENTLY FITTED OUT 3 VEHICLES WITH DROP BOXES 3" & 4" .
THEY BOLT IN WITH SOME MINOR GRINDING. COST IS $350
CHEERS JOHN

Just to clear it all up....

Drop boxes can be made to suit bigger lifts.
At the moment the drop boxes that Superior Engineering make and sell are smaller and suit 3"-4" lift. You may get away with em for a 5" lift though.
We did this because 4" lift is a prick for castor correction. Plates are usually to much positive castor and bushes not enough. No body seems to really want castor bushes anyway

Drop boxes and those droped radius arms do have different characteristics not least of all the difference in price!!!

One of our customers actually had some of those on his Gu and when he went to drop boxes noticed a positive difference in the way the truck drove on the road.

The dropped radius arms do nothing for the the fact that the angle between diff and rear mount has increased. They are made so the pin goes thru the mount straight but the angle is where a lot of the problem is.

the drop boxes seem to allow the car to absorb bumps a lot better by forcing the impact up thru the spring and shock like it should.
Arms do not help considerably here.

There are disadvantages to the drop boxes in that you loose a bit of clearance behind the front wheel but with our design this is minimal and for the average 4wder it is not a problem. They can and are used for more demanding offroad as well.

This should link to a pick of em installed on my truck

Have you guys made a version of these drop boxes which allows us to remove the bolt on pin in the back of radius arms on GU and convert to eye (like cruiser).

There would be a bit more to it to that. Would probably have to get a custom arm made ??

Unless they built a swivel into the drop box itself. Strength issues asside this could work but wouldn't be readily engineerable - just seems dodgy.

Also think the difference in usable travel is negligible. The front binds up pretty quickly with swivel or pin arrangement. However you would get a bees dick more travel

custom arm?... unbolt pin from arm, cut pin off, weld on eye, bolt back into arm- box could be designed with bolt to go through newly bushed eye on back off radius arm- Superior could even supply the new eye in a kit (with the drop boxes) already welded up so it could be bolted into your own radius arm. The bushes would last longer than Nissan pin setup + plus more artic but with stability.
