WHY SPACERS ARE BAD!!!!!1.) Your ball joints are your limiting devise on down travel and will wear them out or break them. 2.) the over extended down travel can cause your CV axles to over extend and wear faster than expected or break while flexed off road.
Spacer lifts aren't bad if you install them correctly, and as long as the spacers don't lift the truck too high. Issues arise if the spacers are too high, causing issues with suspension. Mild spacer liftsare great for off-road and can even improve the off-road ability.
For those of you out there that are running bigger than a 2 inch lift, your vehicle is illegal. If you have bigger tyres than standard and a 2 inch lift (or bigger), your vehicle is also illegal. The only way this does not apply is if it has been signed off by an engineer.
No existing federal law says wheel spacers and adapters are against the rules for on-road use, however, local inspection offices do have the authority to say otherwise. Most wheel spacers manufacturers market their spacers as being intended solely for off-road use to avoid any potential issues.
A spacer will give a fixed amount of lift that will never change. The coil spring, used in conjunction with a spacer, can change lift height (due to wear or a change in weight), but the spacer will never change height. A spacer will never improve the ride, and it generally will not change the spring rate.
Extended shackles and block lifts are illegal in all states.
The NSW Roads Minister has made changes to the light vehicle modification laws allowing 75mm vehicle lifts. THE NSW MINISTER FOR ROADS, MARITIME AND FREIGHT, Duncan Gay, has announced changes to the laws regarding light vehicle modifications in NSW, allowing for vehicle lifts of 75mm without certification.
California. California has considerably more strict lift kit laws in place. Frame height and body lifts are limited to just five additional inches. Aftermarket parts are allowed.
Re: are strut spacers legal? At the moment strut spacers are not illegal but extended shackles are definitely illegal in both NSW and QLD. If you are planning on doing a bit of off road work, coil spacers are not recommended as they limit up travel (bump) and force the spring downwards and over extended the droop.
IFS / Strut Front SuspensionMetal - coil strut spacers, generally bolt in between a coil strut top hat and the strut mount on the chassis, spacing the entire assembly down. As the strut remains basically unchanged, full articulation within the limits of the bumpstops is preserved.
Duncan Gay, the Minister for Roads, Maritime and Freight in NSW, has recently announced via Facebook, that the laws surrounding vehicle suspension lifts have changed. Now, you can lift your 4X4 a total of 75mm: 50mm through the suspension, and 25mm through the tyres.
Coilovers, Lowering springs, Slammed, modified suspensions usually need to be Low Volume Vehicle Certified. The Low Volume Vehicle Certification is what stops your car from killing you, or someone else, and saves the Police from having to put Pink Stickers on your car.
The laws in NZ are very strict on most modifications and require LVV (Low Volume Vehicle) certification; my understanding is that anything up to 50mm of suspension lift doesn't require LVV certification at present.
You must get an LVV certification before you can get a WoF. LVV certification can cost between $250 and $800 depending on the extent of the modification. The LVV certifier arranges to get a plate for your modified vehicle. You must go back to the certifier who will fit the plate to a permanent part of the vehicle body.
A vehicle can be LVV certified with a suspension height of less than 100mm; as part of the certification process the LVV Certifier will ensure (amongst other items, refer to the LVV Suspension Standard) that the vehicle has adequate suspension travel and clearance to bump stops, and that the suspension performs
They have been required by law in NZ since 2010 for vehicles first registered in NZ on or after May 1 2010 and manufactured from January 1 1990 where a catalytic converter was originally fitted (exemptions available for motorsport vehicles).
Does an auto to manual gearbox conversion require certification? Yes, all gearbox conversions require certification as the braking system has usually been affected with alteration or modification to the brake pedal-box.
Structures and Frontal Impact:A body lift on a body/chassis vehicle (commonly a 4x4) always requires LVV certification.
A vehicle fitted with a quick release steering wheel must always be referred for LVV certification and is only permitted within strict criteria. clearance is maintained between all components, when tested from lock to lock at full droop.
Just as you can't fit seat belts to a vehicle you also can't remove them if you intend to use it for road use. At entry and first certification the vehicle is recorded as having a specific number of seats/belts for occupants and loaded into the LTNZ database. This then is a WOF requirement.
This means that the standard body vehicle can have a wider track – the edge of the tyre tread can move out 40 to 45mm on each side, almost as far as the wide body, without need for LVV certification.
As per the wording on the Engine and Transmission page of the VIRM, “LVV certification is always required for the fitting of a supercharger or turbocharger as a modification, or the upgrading of a supercharger, turbo or wastegate, or the re-chipping of electronic engine control units (ECUs) on turbocharged vehicles.”
There is no difference, same blocks can be used for lifting or lowering. If you want to lower 3", the blocks go between the rear leaf springs and axles.. hence shifting the rear axle up 3".
