Mini 4WD Side Mass Damper Set (for MA Chassis)

The Hobby Hideaway Verdict: Ultimate Stability for High-Speed Jumps! The MA Chassis is known for its incredible speed and mid-ship motor efficiency, but that power needs to be controlled when the car leaves the ground. This Side Mass Damper Set is the perfect solution to prevent your machine from bouncing out of the lane upon landing. At Hobby Hideaway, we recommend this set for any racer looking to transition from a basic out-of-the-box build to a competitive, track-ready machine that can handle aggressive slope sections.

Keep Your Mid-Ship Power Planted Mass dampers are critical for absorbing the kinetic energy of a landing. When your car hits the track, these weights move upward and then slam down, effectively pinning the tires to the surface and preventing a secondary bounce. By mounting these specifically on the side stays, you keep the center of gravity low and centered, which is vital for the balanced handling characteristics of the MA platform.

Expanded Chassis Compatibility While this set includes FRP plates shaped specifically for the MA Chassis, the universal nature of the standard hole spacing makes it a versatile tuning part. It is directly compatible with:

• MA Chassis (Optimal fit)

• AR Chassis

• FM-A Chassis

• VZ Chassis

• Super XX Chassis (When using side stay attachments)

Key Features & Technical Specs:

• Targeted Stability: Specifically engineered to counteract the rebound of the dual-shaft motor platform.

• Complete Hardware: Includes FRP side plates, heavy block-style mass damper weights, screws, nuts, and stabilizers.

• Adjustable Tuning: Use the included spacers and long screws to adjust the stroke (the travel distance of the weights) to suit different track layouts.

• Genuine Quality: Essential upgrade for guaranteed fitment and race-legal compliance.

Hobby Hideaway Pro Tip: To maximize the effectiveness of these dampers, ensure the weights can slide freely with zero resistance. A great trick is to use a small piece of fine sandpaper to lightly polish the vertical screws before installation. If the weights hang up even for a fraction of a second, they will not absorb the impact correctly. Also, try different weight positions—placing them further forward or backward on the side stay can significantly change how the car behaves in the air!
