  7. Andtew (verified owner)

    Great product easy fit looks great, purchased 4mm stainless kit for my 2022 dmax fitted with offroad Animal predator bar. Couldn’t be happier.

  8. Mark (verified owner)

    Awesome gear, the factory bash plate for the transmission on the dmax is plastic, the custom offroad plate is 3mm stainless steel which is definitely going to give much more peace of mind when offroad. The underbody protection is built extremely well and easy to fit. Highly recommend for the extra security against damage to the underbody…

  9. Mick (verified owner)

    Solid and very impressed with the finished product A perfect fit – not a hole out of place
    Well done

  10. Phil Davis (verified owner)

    I purchased a two piece, 4 mm sump and gearbox protection. Extremely heavy with it easy to fit strong you could jack off if you had to..
    The only thing I would suggest is to change out the very thin, mud guard washers for something a little heavier / thicker just a small suggestion.
    Extremely happy with the product 10/10👍

  20. Dion (verified owner)

    Had them a week and they payed for them self. A potential diff/sump destroying hit. Bent them out of whack, took some persuading to get them back into shape thanks to 4mm stainless. Really solid, even when they were all bent up they still came on and off easily.

    Fast delivery, great product and easy to fit!

  22. Les Nelson (verified owner)

    Hi just fitted my bash plates to my 2021 D/Max look so good, as i had them painted black easy to fit and the 4mm gives me a lot more places to to go in the bush now.

  23. Shayne Spencer (verified owner)

    Awesome quality, I had a Piak bashplate prior which had more clearance than the custom offroad ones but definitely not as strong.

With your purchase of the Stainless Steel plates, make sure the plates fit before removing the protective film. If your plates don’t fit or have any other problem, the protective film needs to stay in tacked in order to receive a replacement set or a refund.

We have included a variety of bolts, and across the year ranges the bolt holes remained the same but the bolts may have changed. The bolt threads in the chasee are 1.25 fine pitch thread. The 30mm M10’s supplied with nut plates are a standard thread not to be used in the chassis. This will only be valid with three piece sets, not for two piece sets.

Front and Sump Plates

Start with the sump plate (start with trans plate if 3 Piece kit). This will go directly under the motor. The back of the plate will share the bolts with the front of the transmission plate. When installing the front plate, line up the back of the plate with the front of the sump plate and use the same bolts. This will line the front of the plate to the existing holes. Always overlap front to back.

Transmission Plate

Nut plate needs to be inserted inside the transfer cross member to give a thread for the transmission. The transmission plate will share the bolts of the sump plate and will use the 2 x 30mm M10 bolts to connect plate to the nut plates.

Is it in stock?

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!

What is a Diff Drop?

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!

Does it fit with my brand of Diff Drop/Bull Bar?

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.

Why do I need to upgrade my underbody protection plates?

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.

What thickness do I need?

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.

Stainless or Mild Steel?

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.

What is the Weight of the Plates?

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.
