4x4 Wagon Sound Deadening Pack

Reduce Noise & Heat for a More Comfortable 4WD Touring Experience

Upgrade your Nissan Patrol, Toyota Land Cruiser, or similar-sized 4x4 wagon with a comprehensive soundproofing and thermal insulation pack. Whether you’re tackling long highway drives or off-road adventures, this pack is designed to reduce road noise, block heat transfer, and improve cabin comfort.

Each pack provides maximum coverage using high-quality materials engineered for Australian conditions.

 

Choosing the Right Pack – A Simple Guide

Picking the right pack comes down to two key factors:

1️⃣ Where do you want to cover?

  • Floor pan only → Standard Pack 1 or Premium Pack 2
  • Floor pan + doors → Premium Pack 3
  • Full vehicle (floor pan, doors, and roof) → Premium Pack 4

 

2️⃣ What type of underlay do you prefer?

  • Standard (Waterproof Underlay – peel & stick foam) → Pack 1
  • Premium (Mass Noise Liner – superior sound-blocking blanket, removable if the vehicle is submerged) → Pack 2, 3, or 4

 

Optional Upgrade – Extra Sound Deadener for the Cargo Area

The ribbed cargo area design naturally helps to reduce vibration and noise, which is why sound deadener is not included as standard—keeping both costs and weight (approximately 7kg) down.

However, many customers prefer to fully insulate the cargo area floor for complete coverage and a uniform finish. If you choose this optional upgrade, you’ll further reduce vibration noise, creating an even quieter and more insulated ride.

* If selecting this option, apply Stage 1 Sound Deadener before installing the Mass Noise Liner (MNL) in the cargo area.

 

Standard Pack (Pack 1) – Covers Floor Pan, Inner Quarter Panels & Rear Wheel Arches

Total weight: Approx. 30kg

3 Boxes (5.4 sq/m) of Stage 1 Sound Deadener

Land Cruiser 76 wagon pack 4

By: on 23 May 2022
I have taken some more readings for the 76 post installation of the sound deadening materials. As a baseline, we were driving on the hiway into Melbourne, so smooth roads, we have standard Dunlop tyres that come with the vehicle, we had the windows up, the radio was off, and we were not talking. Before installation, at 80 kph we were experiencing consistent noise at and above 85db, post installation I have taken readings at a consistent 62db. Before installation, at 100kph we were experiencing consistent noise at and above 90db with peeks of 96db at 110kph, post installation I have taken readings at a consistently below 70db, but with peaks at 72db at 110kph. The 76 now feels more solid, the doors close with a thunk instead of a tinny sound. The roof feels solid and sound. All in all this installation has completely transformed the vehicle. Please pass on my thanks to the team. I hope these readings assist

Wagon Pack 3 install

By: on 20 February 2021
purchased the wagon pack 3 and installed stage 1 & 2 over a few days in my 76 series landcruiser. I used the sound deadener on the floor from firewall to boot, on the roof from front to rear. As I was doing the doors and wheel arches I ran out on the last quarter panel and barn doors. A final box was purchased separately and easily finished the job with material to spare. As I started stage 2, the roof was very easy. Triple check, cut once. Job done. The mass noise liner lite was very tricky. It works well but very hard to work it into shape. Just a suggestion but maybe a included template or something online to help install would be fantastic. Overall im very happy with the install and the kit. Works amazing and highly recommend. Thanks carbuilders

So easy to install!

By: on 29 October 2020
I have just finished installing the roof sound deadening and heat insul layer and was amazed at how easy it was to install. Looking forward to finishing the rest of the interior with the last part of the pack

Awesome product!

I Installed the premium pack sound deadening materials in my Landcruiser 76 and boy, what a difference it makes! The Toyota Landcruiser 70 series can be very noisy on the road, and even more so with a set of muddies. This system is already working very well at keeping outside noise out and I still need to finish work on the doors! Can’t wait to see the final product in action because, as I said, this system is just awesome and a worthwhile upgrade to my 76. I would highly recommend these products to others.
