L-Series Engine 3D Printed Velocity Stacks (Shorties)

Short velocity stacks for the L-Series engine — 3D printed for precise geometry and a clean, purposeful look. Designed by ZSM Custom for ITB and carbureted L-Series setups where space is tight and airflow matters, these shorties deliver a smooth, bell-mouthed intake entry without the height of a full-length stack.

Velocity stack length affects where your torque and power peaks fall in the RPM range. Shorties favor top-end breathing — ideal for high-revving L-Series builds, track use, and setups where hood clearance is a constraint.

Features

• Short ("shorty") velocity stack profile for top-end airflow optimization
• 3D printed for precise, repeatable geometry
• Smooth bell-mouthed intake entry reduces turbulence
• Designed for L-Series carburetor setups
• Lightweight construction
• Sold as set of 6 stacks 

Fitment
