STOCK UPDATE! 🥳

We've had a super small delivery arrive, but it comes with news that more stock is on it's way!

Keep your eyes peeled on emails for tracking updates, and just a reminder that we don't recommend using the ShopApp for tracking - it doesn't always play nice 😉

Cheers legends!
Team Munji 😎🤙

Just a heads up that we will be closed on Monday 5th October for the public holiday.

Jared is also going to be a bit hard to contact over the next couple of weeks. We're stressing out with all the big things we've got planned before the end of the year, so we've made the collective decision that Jared needs some time off (and we need to put our big boys and girls pants on). 😌

While he's away, please call the office on 07 5670 8147 or shoot through an email to [email protected] (and if it's urgent, please pop urgent in the subject line).

Cheers legends and we'll be back on board on Tuesday!
(... well, most of us 😉)

Have a great weekend and travel safe!
- Team Munji 😎🤙

Quality vs Cost!

What does everyone prefer? Save a few bucks for a cheaper part that will possibly work the same, or pay extra for a better made proven part?

We have the option to supply a cheaper cooler with our transmission cooler kits and pass the saving onto you guys and girls, but we want to know what you’s want!

⚠️ STOCK UPDATE ⚠️

We've had some updates come through overnight that our stock we've been expecting to pop by is wishing it was going 480 down the Mooney-Mooney bridge, but unfortunately it's still just waiting on a mate. 😪

Our shipment that we were expecting to see over the last few weeks has been delayed. The word on the street is that the ship has had to make an unexpected return back to the home port.

Our production and manufacturing team - the legends that they are - are going to organise to have it sent back to us via air freight, but until we receive the notice that it's on the way, our hands are unfortunately tied. We will be updating both our socials pages and the product pages as we get information coming through, but if you don't see anything new, it just means that we don't have any new information to give.

❗️ Delayed:
➝ Front Upper Control Arms (to suit RA, RA7, RC, Early Dmax - SKU: I-S1-UCA) - All colours and variants
➝ Front Upper Control Arms (to suit Dmax & Colorados 2012-2020; MUX/Colorado 7 2013-2021 - SKU: I-S2S3-UCA) - All colours and variants
➝ Offset Rack Drop Kit (SKU: I-S4-OSRD)

🥳 On the way (awaiting tracking confirmation):
➝ Top Mount Intercooler EGR Cooler Delete Kit (to suit 2007-2012 4JJ1 - SKU: I-S1-EGR_CD-TMIC)
➝ MAP Boost Reference Adaptors (for all models - SKU: I-S1/S2S3-MAP BRA and I-S4-MAP BRA)
➝ Rear Tail Shaft Spacers (to suit RA, RA7, RC, 4JJ1 Dmax, 2012+ MUX - SKU: I-S1S2S3-RTSS)
➝ 2" Body Blocks (

We should also be seeing some tracking come through for our next shackles shipment, as well as our next production order update, within the coming weeks.

There's lots happening at Munji HQ at the moment, with more updates to come (not just for stock - so keep your eyes peeled 🫣😉), but as always, stay safe legends, and thanks for bearing with us!

MUNJI Compound kit all fitted up and slowly getting dialled in! All the tuning is being done via the factory ECU, which means a simple change can take almost half an hour to make!

Factory airbox has also been retired, unfortunately over 320hp it starts to hold us back. If you Legends have any good suggestions for a quality airbox, drop em below!

Dylan’s 2WD RC in for a midlife refresh! After fitting a set of +30 Injectors and blowing through his clutch, Dylan brought us the ute for a new clutch and tune. He is also running an early prototype of our front mount intercooler kit and a cat back exhaust.

After fitting a new genuine rear main seal and an upgraded clutch, we got this one on the dyno to see what it could do.

Starting at 175hp thanks to the larger injectors, we had to spend some time dialling in the map for that flat AFR. All in all ending up with a healthy 245hp at ~16:1AFRs, and 670nm!

With a more free flowing exhaust the stock turbo will be able to breathe a bit better and get us that little bit more, but this is already rowdy enough to get you giggling 😂

Brayden’s 2015 D-Max in for the full build!

After purchasing his new D-Max, Brayden brought it to us bog stock to pull the injectors and get them tested, then fitted with +30 Genuine Denso caps from the boys at Desta Automotive. That along with a Ratio Tek Valvebody and Sonnax Zip kit was all installed inhouse to prep for some power out of this 4J! While we had it apart we also did some 3D scans to design our Custom Transmission Cooler kit for the 2012-2020 D-Max and MUXs.

Then with the lift, we supplied 2.5” Radflos set around 3 inches, Blade Suspension’s amazing adjustable Leaf Pack and of course our full suite of suspension correction including our UCAs in Raw Silver and our Diff Drop Relocation. Brayden got that all installed himself and brought it back for the wheel alignment to get dialled.

While we had it in the second time we fitted up our prototype transmission cooler kit, which pairs perfect with the gearbox upgrades we done for longevity and towing ability. With the big Cross Country Cooler Brayden also installed we put it on the Dyno and dialled in the custom tune to make a nice stout 218hp on the 33s. Since Brayden does a bit of towing we kept it at a safe and easy ~17:1AFR at 25psi, which will keep this thing going forever 💪🏿

Now this rig is set up for Brayden to use!

A bit more RnD on the MUNJI TF Rodeo swapped with the late model ISUZU RZ4E motor!

The horsepower is a little lower then actual thanks to the Jackaroo wide track rear diff with its ~4.5:1 ratio and tiny tyres, but still starting around 125hp and ending up with 160hp at the wheels, this thing shoot scoot now!

Next up, another turbo 😉
