OVERDOSE Aluminum Front Bulkhead Type-3 for GALM Series

Ultra-Lightweight Design | Adjustable Caster Geometry | Precision Aluminum RC Drift Upgrade

Take your OVERDOSE GALM RWD drift chassis to the next level with the OVERDOSE Aluminum Front Bulkhead Type-3, engineered to provide advanced steering geometry adjustments, improved chassis rigidity, and significant weight reduction over the previous Type-2 design.

This premium aluminum front bulkhead features an innovative multi-adjustable design, allowing drivers to fine-tune caster angle, upper suspension arm mounting width, and rocker arm positioning to achieve their preferred steering response and drift handling characteristics.

Weighing approximately 24 grams, the Type-3 is approximately 45% lighter than the previous Type-2 aluminum bulkhead, while providing additional adjustment options for competitive RC drift setups.

Key Features

• Ultra-Lightweight Aluminum Construction: Approximately 24g, reducing weight by about 45% compared to the previous Type-2 aluminum bulkhead.

• Adjustable Caster Angle: Continuously adjustable from approximately 4° to 12° when installed on a standard GALM chassis.

• Adjustable Upper Arm Mounting Width: Separate upper suspension arm mounting components allow spacing adjustments using compatible spacers.

• Adjustable Rocker Arm Position: Two forward adjustment positions in 2mm increments help improve clearance between suspension components.

• Reduced Suspension Interference: Revised rocker arm mounting geometry helps minimize potential contact between the pushrod and upper suspension arm at lower caster settings.

• Improved Chassis Rigidity: Precision aluminum construction provides a more rigid alternative to the factory resin bulkhead.

• Advanced Front Suspension Tuning: Fine-tune front-end geometry for different track conditions, driving preferences, and competition setups.

• Premium OVERDOSE Construction: Designed for serious RC drift enthusiasts who demand precision, adjustability, and performance.
