Qld Police defecting lifted 4x4s

Post by Silkwood »

Posted on 4x4 Earth, apparently a story on 7 News (sorry, I can't link to the actual story because it's on Facebook and I am not on that).

https://4x4earth.com/forum/index.php?th ... ast.44558/

Friend in the force here in SA tells me they are being educated on this topic now.

Doesn't take much to be defectable. If they stop you and are uncertain, they will usually add the defect anyway and let Dept. Transport sort out the details.

Cheers,

Mark

If it looks like a defect, then they will look closer to see if it is a defect. The lift limits without engineering are easily available to find on any of the state transport websites.

For determining the lift height they have an online resource called the Road Vehicle Descriptor that has tables of all the relevant factory measurements of overall dimensions, tyre size, ground clearance, rim size and offset, a whole bunch of stuff.

The quickest determination of legality is the tyre size and the lift.
Tyre size, is easy enough, and for lift they measure from the center of the hub to the point on the wheel arch directly above.

For a Ranger and BT50 its 552mm at the front and 600mm on the rear.

A suspension lift will change that measurement, a body lift will also change that measurement and its irrespective of tyres, so a quick look at the relevant page and a tape measure will show if you are outside the set dimensions, a un-roadworthy sticker is applied and then its up to you to prove its good.

To find out what your Road Vehicle Descriptor dimensions are meant to be: http://myrta.com/rvd/searchRVD.do

I was pushing the 50mm suspension lift limit, but a winch has brought it back into specification and the alloy tray on the back they don't have the factory datum 8-)

Is there no other datum point they can check at the rear, Hoyks?

On mine, no as I don't have the tub with wheel arches as a reference point. They could probably measure the gap on the bump stops if they wanted to crawl under the car, but it has settled and would be within the 50mm now anyway.

Rear leafs they always measure the bump stop gap.

It's started in NSW as well.

A HWY Patrol pulled a GU Nissan Patrol over just in front of me.

On my way back seen the patrol parked up so I stop an asked what he was done for. Defected for larger tyres (315/75-16 from memory) and raised suspension.

No sympathy really. There are rules to follow for up sizing the suspension and tyres. Its easy to find what you can do legally with no certification required.

There are stated lifts you can do yourself and where you have to employ the services of an engineer to certify you have done it safely as going that far outside the basic vehicle design will change steering geometry and vehicle stability. Its gets you into modified or specialist radius arms, extended braided brake lines and other expensive bits.

Patrol owners seem to be overly represented in doing it on the cheap by just shoving some taller springs under it and calling it good.
