Legality of snake shackles on road in NSW

[lokka]

Ok guys want to know what the go is with running the snake shackles on the road in NSW without having them engineer approved is this legal or not ..

Reason being i was defected as the officer called them a dodgy set of shackles ...

Any help on this matter would be great

Extended shackles are illegal. You're not going to get them engineered either, as they are one modification that is specifically mentioned as illegal.

Yep your right ive since found the info on the rta web site heres what they say ..

However, the following suspension modifications are not acceptable:

􀂄 Welding forged components such as stub axles or control arms.
􀂄 Fitting longer, non-standard shackles to leaf springs.
􀂄 Fitting any additional components or altering the suspension so that the wheels or tyres may contact any
component under the full range of suspension and steering travel.
􀂄 Fitting any additional components or altering the suspension ride height so that any part of the vehicle other
than a wheel or tyre can contact the road in the event of a tyre deflation.
If major changes to the suspension (such as substitution of a non standard front cross member) are carried out, they
should be done under the strict guidance of an engineering signatory.

extended shackels are ileagle as they are dangerous, Shackles are set up with springs at a specific lenght to achive a specific angle which allows the spring to function effectivly. If you alter the angle by fitting longer of shorter shackles you put increased forces on areas of the pring that can and will cuase the spring to crack or bend. If a shackle has to sharp of an angle it can allow it to reverse on the motion from full extension when coming back down to normal or fully compressed causing damage. If you want to fit a longer shackle you must also have either a shorter spring or extend the mounts to achieve the same angle as factory, in this case it would be engineerable, but a longer shackle to achive dodgy lift is unsafe and should not be done and shops should not sell these even for "offroad use only"

A drop shackles could possibly be engineered provided you maintain the same angle, have the shackles locked for road use and prove they are built as to ensure the same of increased strenght over factory is maintained, however drop shackles create other problem in an offroad environment and create false articulation.
