Albins st6 6 speed sequential

The Albins ST6 is a heavy-duty 6-speed sequential transmission originally designed for Australian V8 Supercars and now widely used in Trophy Trucks, endurance racing, and high-performance circuit applications.

It is known for its 1,100Nm torque rating, lightning-fast shift times (as low as 40ms), and a compact design that includes an internal oil pump and a unique “drop gear” system for rapid ratio changes.

Core Technical Specifications
According to manufacturers and technical documentation from Albins Gears and Weddle Industries:

Torque Capacity: Rated for 1,100Nm (approx. 811 lb-ft) of continuous torque in off-road environments, with some drag applications handling up to 1,500+ HP.

Weight: Varies by configuration, typically between 99 and 180 pounds (approx. 45–82 kg).

Gear Design: Features straight-cut, profile-ground gears that are shot-peened and isotropic polished to reduce friction and heat.

Shift Mechanism: Uses a roller barrel selector, which eliminates the “gritty” feel found in some other sequential boxes.

Maintenance: Includes eight inspection ports that allow for visual checks of gear and dog wear without disassembling the unit or draining oil.

Available Models and Applications
The ST6 series is highly modular and can be configured as an inline gearbox, mid-mount transaxle, or rear-mount transaxle.

Albins ST6-i: An inline version primarily used in Trophy Trucks and front-engine RWD race cars.

Albins ST6-M: A mid-mount transaxle version designed for mid-engine RWD vehicles, such as those used in sports car racing.

Albins ST6-LP: A “Low Profile” inline version designed to fit into standard transmission tunnels (like those for Tremec T56/TR-6060) with fewer modifications.

Albins ST6-IR32: A specialized bolt-in 6-speed sequential unit for the Nissan Skyline GT-R (R32/R33) that retains the standard crossmember and transfer case
