4WD Underbody Protection or “Bash Plates” designed and made by Custom Offroad are an essential part of every D-Max 4×4 set up for offroad adventures. They are designed to protect the underside of the D-Max vehicle from any objects that could cause damage. Whilst most factory protection is sufficient for protecting your vehicle from stone damage, a more robust solution is required to increase protection from rocks, stumps and ruts encountered in more challenging terrains.
Custom Offroad Accessories 4wd bash plates are a minimum of 3mm thick. Our plates are designed to take hit after hit so your vehicle will make it through its 4×4 adventure. They protect the vital components without compromising performance and durability while looking good at the same time.
Be prepared; bash your plates and not the vulnerable areas of your D-Max 4WD.
Our bash plates are designed to protect the important parts of your underbody including the steering, sump, transmission and transfer case.
Our range of plates are 3mm to 4mm, and the ideal thickness depends upon the vehicle and what kind of four wheel driving you are doing most often. Thicker is not always better, since the plate needs to absorb as well as deflect any impact. For this reason, bash plates need to have some flex in them as well. If you are unsure, then feel free to get in touch with us for advice on what plates would best suit your needs.
The most popular setup is 3mm stainless, as these plates are great for general 4wding and will last you for years and give you peace of mind. If you like to go a bit more rugged in your driving and want the extra strength, then the 4mm stainless is for you.
Our bash plates are highly durable, and are designed specifically to last and to prolong the life of your 4×4, rather than to be something that you need to replace often. Don’t get left behind stuck because you are using inferior factory bash plates or cheap competitor copies just because you wanted to save money.
The package comes ready to fit as is for a direct bolt-in installation. All parts are supplied with instructions on how to fit your new bash plates. No cutting or welding needed.
As always, if you have any questions, please give us a call on 0477 799 639
NOTE: Please read and understand the Installation Instructions before beginning the installation process. Retain the installation instructions that came with the kit for future reference. Where possible it is recommended this item is installed by a Qualified Person. Please contact us if you require installation.
In a market saturated with an endless list of must have upgrades for your 4×4 often underbody protection is overlooked. Vehicle manufactures do not consider bash plates essential to the performance of the car even though they are producing cars for offroad use.
Over the years, the market has seen a shift away from the older live axle cars to the more comfortable riding independent front suspension “IFS”. Whilst making the car more pleasant to drive this means vital components such as the radiator, sump, diff actuator and transfer case become more vulnerable.
Vehicle owners are often unaware or reluctant to invest in bash plates as they consider their offroading to be tame or “only beach use”. Some of the worst damage we have seen to the underside of cars has been sustained on the beach navigating a cutting or hitting a washout at speed. Often the damage will render the car un-driveable with split radiators or damaged actuators making the car 2wd.
Bash plates should be one of the first modifications carried out before heading offroad. The damage that can occur, the cost of recovery and repairs vs the purchase price is a simple equation.
Many enthusiasts consider the thicker the plate the better! This is true to a point but what some “experts” don’t consider is when your plates sustain a hit the pressure and shock has to be absorbed somewhere. If the plate has no flex what so ever the shock is then put back into the mounts which are welded to your chassis. It is much easier and cheaper to replace bash plates after a few years rather than repairing your mounts or chassis!
We offer a range of thicknesses based on your preference, vehicle and type of 4 wheel driving. With plates ranging from 3mm to 4mm for the more common dual cabs through to 4mm standard for heavier vehicles.
After countless 4wd trips the one thing I kept replacing the most was my underbody protection. Although they did get a good beating the main problem was the rust factor, especially from my love of beach driving.
My car would look great all polished and washed except for underneath that was bent out of shape and covered with surface rust. I designed a set out of stainless steel because of the resistance to corrosion and the strength to get a better, more durable life out of my bash plates.
The stainless steel comes in a 2b matte grey finish which holds up great against scratching and with the extra strength of the stainless I’ve tried my best to knock them out of shape with no success. If you are after a bash plate that you would like to put on and not have to change every 6 months stainless is the way to go.
Built using qulaity stainless steel, our Bash Plates provide the perfect weight to strength ratio for your 4×4. As each Make and Model is different so too is the weight of each plate. However, as a general rule, a 3 piece set of 3mm thickness, usually weighs between 24kg & 30kg, while a 3 piece set of 4mm thickness, usually weighs between 35kg & 40kg.
Please consult the product page of the vehicle you’re interested in for an accurate weight for those Bash Plates.
Our aim is to consistently maintain our stock levels so that we can get our plates to you as soon as poosible. However, in the event your plate is unavailable, the turnaround is generally between 1 to 2 weeks. This timeframe is well below the industry average as our plates are made right here in Brisbane, Australia!
A diff drop is a modification that physically lowers your diff away from the chassis in order to bring the CV angles back into alignment and closer to the factory specifications. Ultimately, the reason for considering a diff drop is to minimise the CV shaft angle that is increased by the addition of a suspension lift. As a general rule, if you have lifted your suspension by at least 2 inches then you should consider dropping the diff!
Our plates are designed to fit with a large range of bull bar setups. If your 4WD currently retains the factory plates, and has a bull bar installed, then our plates will fit. The majority of our bash plates support a diff drop, however, we advise you consult the individual product pages for more information regarding the make and model of the 4WD you wish to fit plates to.
