Spindle Duct LH Dual

The Spindle Duct LH Dual from ALLSTAR PERFORMANCE is a precision-engineered cooling component designed for serious engine builders and track-focused enthusiasts. This left-hand spindle duct channels air directly to critical brake and suspension heat zones, helping to reduce thermal buildup during sustained high-performance driving. It is suitable for both road course competitors and street machines prepared for aggressive driving.

This dual-port spindle duct is engineered with precision flow dynamics to maximize air delivery while minimizing restriction and drag. Its compact form factor of 8.05 x 3 x 11.05 inches integrates seamlessly into most front suspension packages without interfering with steering geometry or brake hardware. Weighing just 0.59 lbs, it is designed to be lightweight, which is a critical consideration for suspension tuning.

The dual-inlet design allows for independent tuning of left and right cooling circuits, enabling users to balance thermal loads across the front axle. This feature is particularly beneficial for road racers, autocross competitors, and street performance drivers who require consistent braking performance during extended driving sessions. Installation is straightforward, requiring basic mechanical knowledge and standard hand tools, as it mounts directly to the existing spindle assembly.
