1/10 GRANITE MEGA 665 4X4 RTR Brushed Monster Truck, Blue Overview

Bash with unbeatable 4x4 grip when you step up to the 1/10 scale ARRMA GRANITE MEGA 665 - a ready-to-run brushed monster truck that offers amped-up power and toughness straight out of the box. Later, when you’re ready for even bigger performance, upgrading it to a brushless power system is drop-in easy.

There’s no better way to start your off-road bashing power trip than with the ARRMA GRANITE. And this updated GRANITE MEGA 665 4x4 takes the popular brushed monster truck’s impressive capabilities to the next level.

A high-torque, 11% larger MEGA 665 brushed motor replaces the 550-size motor of its predecessor, with an aluminum heatsink and 35mm cooling fan to boost efficiency and power. The included transmission is already 3S brushless-ready for future upgrades. It’s also protected against damage from excessive torque by a new, maintenance-free overload coupling.

The all-terrain suspension and oil-filled, coilover shocks soak up bumps. You can adjust the ride height to add more ground clearance for uneven surfaces. In any conditions, the multi-surface dBoots Fortress MT tires provide awesome traction. Extended height side guards on the strong composite chassis help keep onboard components free of dirt and debris.

The GRANITE body comes factory-finished in several fresh color schemes, and now uses a clipless body retention system to preserve its realistic, aggressive looks. High-quality Spektrum electronics round out the ready-to-run package, including an SLT2 2.4GHz transmitter, LiPo-ready SLT 2-in-1 40A ESC/Receiver, and S661 digital metal-gear servo for precise, powerful steering.

Just add your own battery and charger. Then, take your ARRMA GRANITE MEGA 665 4x4 to your favorite dirt, gravel, or short grass bashing grounds. Set up some ramps or dirt mounds. Grab the transmitter, punch the throttle - and get set for some monster bashing fun!

BRUSHLESS-READY TRANSMISSION

With a 3S brushless-ready transmission included as standard, the ARRMA GRANITE MEGA 665 4x4 is equipped for an easy upgrade to brushless power for greater efficiency and higher power whenever you’re ready.

OVERLOAD COUPLER

The GRANITE MEGA 665 4x4 monster truck includes an overload coupling (torque limiter) instead of a slipper clutch, to reduce maintenance and protect the transmission from excessive torque.

RUGGED VENTILATED CHASSIS

The durable chassis is ventilated to keep on-board components cool. Larger side guards provide maximum protection from dirt and debris. Stealth monochrome electronics are included for good looks, and the battery straps adjust to accept your choice of 2S hardcase LiPo battery.

MONSTER TRUCK BODY

The realistically styled GRANITE MEGA 665 4x4 monster truck body is held securely in place by a hidden clipless body retention system. The body comes in a choice of bold, factory-finished color schemes.

SPEKTRUM ELECTRONICS

High-quality, waterproof Spektrum electronics are installed for worry-free bashing in any conditions. The SLT 2-in-1 40A ESC/Receiver is LiPo-ready. For precise steering, ARRMA includes a powerful S661 metal-gear digital servo that produces 125 oz-in torque at 6V.

SPEKTRUM SLT2 2.4GHz TRANSMITTER

The included Spektrum SLT2 transmitter is perfectly balanced for fatigue-free bashing and has a foam wheel for precise fingertip control. Less experienced bashers can set the throttle limits at 50% or 75% until ready to use the monster truck’s full speed potential.

MEGA 665 MOTOR

Faster, more powerful, and 11% larger than the 550-size motor of its predecessor, the GRANITE MEGA 665 4x4 monster truck's 14-turn MEGA 665 High Torque Brushed Motor includes an aluminum motor heatsink and 35mm motor cooling fan to boost efficiency and performance.

ADJUSTABLE SUSPENSION

The GRANITE MEGA 665 4x4 monster truck’s all-terrain independent suspension and oil-filled, coilover shocks soak up bumps. If your bashing takes you over uneven surfaces, you can adjust the ride height to increase ground clearance.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil
