Not sure which material and thickness to 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 great for general 4wding, will last you for years and give you piece of mind.

    Fantastic product and customer service.
    Would love it if you could do up some plates for the transfer case and fuel tanks. Would buy them in a heartbeat.

  2. Greg Gifford (verified owner)

    Great product ! 1 hour to fit the 4 stainless plates. just raised suspension to off-road 2.
    Excellent quality and look the part. Our Jeep “ Growler” tackles some pretty Gnarly ground and rocky river crossings. Guys can you please measure me up and build a transfer case protection plate ? Full Fuel tank plate ?
    Thanks Greg and Di.

    Great bash plates with good quality materials and workmanship, fitted great, look even better and delivered quickly to Melbourne. How about some protection for the fuel tanks on a Grand Cherokee WK2, I will order as soon as they are made available.

  4. Paul K (verified owner)

    Great build quality, easy to fit and doesn’t sacrifice much ground clearance. Unfortunately, don’t make fuel tank plates which I feel is a serious omission as those tanks are pretty vulnerable. (Managed to track down some elsewhere.) I opted to change the front bash plate mounting bolts to SS button head ones as it looks better and less likely to catch on debris than the standard zinc hex head bolts.supplied.

  5. Robert Martin (verified owner)

    Love the plates great finish easy fit by one person(I was on a hoist) nearly to nice to put underneath the vehicle.pride of workmanship is obvious.

  6. Jimmy (verified owner)

    Great customer service and quick delivery !Product looks great and can’t wait to fit the plates on my Jeep.

  7. Michael Gerhard Lahrmann (verified owner)

    Very good product. Maybe you can extend your bash plate Combo over the fuel tank for the WK2 Grand Cherokee. If you do I’ll buy one. Other wise great product

  8. William Edwards (verified owner)

    Couldn’t have been easier! package arrived a few days after ordering. Put the Jeep up on ramps, unbolted the stock pieces of junk, peeled off the coating from the new 3mm steel plates, using the supplied bolts installed the Custom Off Road Bashplates. DONE. I even picked up the fuel filter guard for a little extra protection. Sweet. Took all of 30 min. one very happy Jeepster.

    Purchased Jeep Grand Cherokee WK2 set of 3 bash plates. Good looking product, fitted without help with all hardware provided. I did have to wait for the product but that was to be expected given all that is going on at present. Bash plates look very solid and professionally made. They certainly look like they will do the job and will allow me to travel without the worry of whats happening underneath.

    Highly recommended businesses and products.

  11. Stephen Jacobs (verified owner)

    Quality really good. Very happy.
    No special equipment or set-up required. Me and my boy installed it without lifting vehicle. Everything fitted precisely.
    Don’t think necessary for anything thicker than 3mm. Solid plates.

  12. Dejan J (verified owner)

  • 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.
