Our Custom Offroad designed underbody protection bash plates will fit all new models from 2015 to 2022.

We always recommend buying the 3 piece set but unfortunately some Bull Bars remove the front plate top mounting brackets.

*Before you purchase a Bull Bar check it does not remove the front plate top mounting brackets!!

Not sure which material choose?

Mild steel is great for short term usage 6 to 12 months. After various knocks Mild steel start to crack and rust over time. Stainless Steel is a far superior metal that endure a lot more hits and beach driving. The most popular setup is 3mm stainless, these plates are great for general 4wding, will last you for years and give you piece of mind.

    Recently fitted the stainless bash plates to my 2019 Ntrek.Fitting them was easy and quick.Look good and obviously provides heaps better protection for the intercooler etc than the original bit of flimsy tin.
    Customer service was good also. They gave me a quick call just to verify everything I ordered online was right and courier delivery was as requested…
    Have no problem recommending them

  5. John (verified owner)

    Love the bashplates and the service given the team. Being all thumbs I had trouble fitting them. The boys said come over and we will give you a hand and didn’t with ease.
    Great customer service

  6. adrian (verified owner)

  7. Shane (verified owner)

    Great product and service. Got my bash plate painted and couldn’t be happier. So easy to fit.

  8. Kevin White (verified owner)

    Bought the complete set for my 2015 STX, had some minor issues getting them to align as I was installing them solo, following the clear instructions helped immensely. Great product, nil issues and would recommend for your own vehicle. Provides peace of mind whenever you choose to go off road, even just that one time…

  9. Peter Francis (verified owner)

    Great product which fitted perfectly. All bolt holes aligned which was unlike the other rubbish brand I purchased. Their plates had to be levered to align the holes & the first sand dune I hit bent the plates.

    Finish was excellent & all laser cut edges were clean with no sharp edges.

  10. Dave (verified owner)

    Fitted the front and sump protection plates to my 2015 NP300 with XROX bar, with little problems. Look great and seem to give great protection.

  11. Neal Carmont (verified owner)

    I’m lovin my bash plates purchase easy install via UTube Vid needed a nav vid but easy none the less glad I found your stall at the last 4X4 show in brisbane

  12. Brodi Mundey (verified owner)

    Awesome bit of gear. Easy to fit once you wrap your head around where the bolts go. Fit straight up to my arb bullbar. No issues at all, love it

  13. Heath (verified owner)

    Product is great and service was as it should be. I sent a few questions about installation and they were answered same day. Unlike some other 4wd accessory retailers who apparently don’t care about your question once you have bought the product.

  14. Ian Goldney (verified owner)

    I fitted a 3 piece 3mm stainless steel set of bash plates to my 2021 facelift Navara. The fit and finish of these plates is superb and looks very neat and solid once installed. Very pleased with the result and feel confident that they’ll provide more protection than I’ll ever need! Highly recommended.

  15. Barack Borkman

    Got a bash plate for my NP300. Saved me countless times up Fraser. Still managed to give it a little bend, but my intercooler is still intact where as it would have been ripped out with the stock bash plate. Very happy with it. Also Simon was great help. Had a couple install questions and he was very helpful

Thank you for your purchase of the Np300 Bash Plates.

If you have purchased the Mild Steel plates, they need to be painted before fitting. If you have
purchased 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.

Please note there is a slight difference between Series 1,2 compared to 3,4. This difference is in the
cross member where the front and sump plate meet. The vehicle comes standard with only a front
plate, so it will be at the back of the front plate. There is 4 holes in the chassis, 2 x M6 bolt threads
and 2 x M8 bolt threads. In the series 3,4 Nissan has removed the M8 bolt threads leaving only the
M6 threads. This will not be strong enough to hold two bash plates that overlap. It is strongly
recommended to get M8 nurtserts in the chassis. This is like a pop rivet with a thread in the middle.
Front and Sump Plates

Start with the sump plate. This will go directly under the motor with the forks to the front. Line up
the front holes and use 2 x M6 bolts and 2x M8 bolts. The back of the plate will use the 2 outer
20mm holes. The 2 Spacers will go in between the plate and the cross member to fill the void. The 2
x M10 75mm bolts will go through the cross member and tighten with the nylon lock nut. The 4 back
holes are for the transmission plate to Bolt too. The front plate is simply using the bolts of the front
of the sump plate so the plates over lap and then bolting up the front holes. Front bolts may vary in
size due to different bull bars, factory mounts use M6 bolts.
Transmission Plate

The transmission plate will bolt to the sump plate using 4 x M10 20mm bolts and nylon lock nuts. It
then will use 2 x M10 75mm bolts to bolt through the transfer case cross member, similar to the
back of the front plate.

Thank You for your purchase

  • 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!

  • 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.
