Reduce Noise & Heat for a More Comfortable 4WD Touring Experience
Upgrade your 60 Series Landcruiser, 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.
