4WD MODIFICATIONS – GENERAL MODS
Modifications you might not have thought about: diff breathers, replacement seats, civilising the ute.
Long wheelbase options for the VW Amarok
For many years we’ve been complaining about the restricted wheelbase and GVM offerings from medium-ute importers. In 2020, VW did something about it.
Weight distribution calculations
These calculation tables are designed to make it easy to assess the effects of payload and towball weight when towing. Caravan and trailer weight distribution can also be calculated.
Steering dampers with a difference from Tough Dog
Many 4WDs come with steering dampers that reduce unwanted reactions from the front wheels through the steering wheel. We checked out two Tough Dog units that differ from most others.
JmacX replacement rear axle for Toyota’s 70 Series
This Queensland company produces a heavy duty rear axle upgrade for the 70 Series V8 LandCruiser. The company also produces coil-spring rear end conversions and 6×6 variants.
Keeping the dust out of your camper or van with Respa
We’ve all done it: opened the camper or caravan and discovered a fine coating of dust throughout the interior. No matter how tightly you close doors, vents and windows, some dust always seems to get inside.
A six-wheeler can solve the GVM issue
Adding a third axle to a 4WD ute can increase its gross vehicle mass to 4495kg – car driver’s licence limit – or higher in some cases. The additional axle carries some of the additional weight and, being braked, increases stopping power.
Typical service bodies
The Service Body business has grown from backyard fit-outs to professionally engineered, purpose-designed units that suit all popular cab/chassis and light truck vocations. Here is a representative sample of service body types.
Suzuki Grand Vitara project
The Suzuki Grand Vitara is by far the most capable SUV on the market. It has useful 1.97:1 low range gearing and is robustly built. However, like most 4WDs it can benefit from additional ground clearance and some under-body protection.
FASP replacement seats
Modern 4WD seats are better than they used to be, but some still leave much to be desired – particularly those fitted to working-class utes and wagons.
Insuring your accessories
It’s all very well loading your vehicle up with accessories, but it’s not so easy getting their value correctly assessed and insured. One company we found stands out from the crowd.
Gross vehicle mass (GVM) increases
As 4WDs become heavier and the list of ‘essential’ equipment increases, many 4WD owners find that their vehicles are overweight. There is a way around this situation, but it mightn’t be cheap.
4WD Modification Legalities
In early 2006 a draft National Code of Practice (NCOP) for Light Vehicle Construction and Modification was released. Since then, there have been several updates, but while no State or Territory has adopted the NCOP, some States have adopted parts of it.
Protecting your ute tub or tray
Nothing on a 4WD ute looks worse than a dented, scarred and rusty ute tub or tray. It doesn’t have to be like that. At OTA we’ve owned several utes over many years and we’ve evaluated three methods of protecting the metal and paint from damage. All have their advantages and disadvantages.
Keeping the dust out
Dust. It looks great in the trip photo album or video, but it’s a gritty nuisance when it gets into your last kilogram of flour.
Modifying electronically-equipped 4WDs
Modifying a recent-model 4WD isn’t the simple operation it was with previous-generation vehicles. Electronics confer greater safety and efficiency, but changes to standard specifications can upset electronics’ programming and behaviour.
Al’s Project 75 Series
Our Outback Travel Australia restoration project, rebuilding and modifying a LandCruiser 75 Series tray-back, is an ongoing exercise. We continue to use it as latest bed for all sorts of gear.
Protecting your vehicle’s looks
Your 4WD is in the firing line for damage, on and off road, so make sure the shiny bits are protected.
Ute Modifications
As today’s 4WD wagons become larger, heavier and ‘softer’ the 4WD ute has great appeal to many off-roaders. However, a ute – even one of the up-market ones – needs the personal touch to fit in with work and bush travel plans
