Mini 4WD Side Mass Damper Set

The Hobby Hideaway Verdict: Keep Your Machine Planted! High-speed jumps are the ultimate test of a Mini 4WD machine. Without proper shock absorption, your car will bounce right out of the lane upon landing. This Side Mass Damper Set is an absolute necessity for racers who want to keep their cars glued to the track and survive aggressive layouts with heavy jumps and slope sections.

Absorb the Impact, Maintain Your Speed When your car lands a jump, the kinetic energy causes the chassis to rebound. Mass dampers counteract this by shifting upward and then slamming down, absorbing that energy and preventing the tires from lifting off the track. By mounting these weights on the sides of your chassis, you centralize the center of gravity, drastically improving your side-to-side stability and jump-landing success rate.

Cross-Chassis Compatibility While this set is specifically contoured and marketed for the aerodynamic AR Chassis, it is highly compatible with other modern platforms! Because Tamiya uses standard hole spacing, the included FRP plates can be directly bolted onto the built-in side stays of the MA, VZ, and FM-A chassis. Even if you run an older chassis without built-in side mounts (like the Super-II or VS), the included block weights, screws, and spacers are universal and can be mounted directly to any standard FRP or carbon side plates you already have installed.

Key Features & Technical Specs:

• Impact Absorption: Includes heavy mass damper weights designed to counteract upward momentum after high-speed jumps.

• AR Chassis Integration: FRP side plates are pre-drilled and shaped to mount perfectly onto the AR Chassis side pods out of the box.

• Broad Compatibility: Can be mounted to the side stays of MA, VZ, and FM-A chassis, or adapted to custom plate setups.

• Adjustable Stroke: The included long screws and nuts allow you to tune exactly how high the weights can travel to match the severity of the track's jumps.

• Complete Hardware Kit: Comes with all necessary FRP plates, mass damper weights, screws, nuts, and spacers for a full installation.

Hobby Hideaway Pro Tip: To get the fastest reaction time out of your mass dampers, make sure they slide up and down the mounting screws with absolutely zero friction. You can lightly polish the screws and apply a microscopic drop of lightweight oil to ensure the weights slam down instantly! Also, experiment with the stroke length (how far the weight travels) by adjusting the position of the top nut; smaller, technical jumps usually require a shorter stroke to recover faster.
