im building some rock sliders for my hilux, for those of you who have got some already how are they mounted? are they bolted through the chassis or bolted over it? if theyre through the chassis do you need spacers through it to stop it crushing the chassis when they get bent?
cheers, ss
Most just make the mounting brackets like a clamp, so they go over/under the chassis rail. Don't need to fit crush tubes unless fitting the bolts through the chassis. Not ideal as drilling holes weakens the rail in those positions. Welding is an option as well. If an engineer signs it off, no cert is required.
hi mate, most people bend up a c shape and run a bolt up the top like these, you can weld em on but need cert and usually its done by welding on a square plate tapped for 4 bolts and then you can still unbolt em

hmmm well since i am an engineer i could do a weldy jobby on it, theyre made from 2 1/2 inch steam pipe so they aint gonna bend anytime soon. gonna need a cert for my lift/engine anyways
I welded drilled and tapped 20mm plate to the chassis but I am certified welder and the vehicle was being certified for many other mods at the same time.
Any qualified engineer with welding tickets can sign it off. Getting 1 to do that is the trouble. Most won't unless they did the welding.
If in doubt easy to check with your local LVVTA certifier.

ah yep cool i can sign my own welding off then so ill do it like that. any idea how much of a roll cage you can put on it? i want a bit more than a roll bar on the back
From memory the regs require an external cage to be no further out than 100mm from body
sweet thats easy enough.
what other work did you do to your wagon?Quote:

4711 is gone now and a lot of tickets now are procedural based ones now? il have a browse and see what comes up
Supercharger,major front suspension modification/chassis modification etc etc
If anything needs LVVC cert everything so there is no questions from cops (not that I ever got pulled up) but mainly for insurance cos if those pricks can find an out they will so even my ride hight tire size/wheel offset was on the plate.
The same basic test is still there and applicable for the same but now if you do overhead you are gifted the other positions which IMO is a bit like "well you can drive a truck so here is your motorcycle and wheels tracks and rollers licences as well.Quote:

I don't know the number of the new one tho I have sat it many times
ha yeah mate thats 2980, I was more wanting to know what the transport agency want you to be qualified in
cheers for the replys tho Im doin a small build now on a vitara
Well I do lots of heavy transport chassis repair/lengthen/shortening so I guess that?
so if i weld plates on I wont need cert? wonder what exactly Im signing off :ORLY:
so for pure strength purposes am i better to weld a 20mm tapped plate to my chassis, or make boltable mounts for around the chassis.
That depends how you make them I spos? I could and did quiet often lift my whole vehicle with a forklift on each slider to change wheels.Quote:

Run them as wide as you can get away with, mine were about 30 mm outside the tires so could just turn into a bank on tight tracks and the bar would push the arse end out and around [emoji4]
I would love to see some photos:P Is 20mm plate a bit over the top? bet she would start getting heavy.
It's only amounting pad from memory about 150mm long x 4Quote:
