This unit comes with the full range of ST6 standard features — including an internal oil pump and filter, inspection ports, and the option of drop-gear fitment for cost-effective ratio changes — and is compatible with a wide range of engine applications through Albins’ off-the-shelf bell housing and adapter range.

Gearbox Specification

Key Features

• 6 forward speeds and reverse — full sequential shift pattern suited to all forms of competition and high-performance road use
• Designed for high-horsepower and high-torque applications — the ST6 architecture is built from the outset to handle the power levels found in the most demanding motorsport applications
• Internal oil pump and filter as standard — self-contained lubrication system; no external oil circuit required
• Inspection ports — internal wear and condition can be assessed without the time and cost of full disassembly
• Drop-gear fitment option — allows ratio changes to be made at substantially lower cost and with a reduced spares inventory compared to conventional gear pair replacement
• Off-the-shelf bell housings — Porsche and GM LS fitments available immediately; extensive adapter range for other applications
• Part and serial number confirmed — Part No. 21250 / S/N 25978 can be verified directly with Albins prior to purchase

Drop-Gear Fitment – Reducing Your Ratio-Change Costs

One of the most practically and financially significant features of the Albins ST6 is the availability of drop-gear fitment as a ratio-change solution. In a conventionally constructed sequential gearbox, changing gear ratios to suit different circuits or events requires replacing individual gear pairs across the mainshaft and layshaft — a process that demands a substantial spares inventory, significant workshop time, and meaningful cost.

The ST6’s drop-gear system provides an alternative path to ratio changes that substantially reduces the parts inventory required and the associated cost. For teams competing across a varied calendar — where the optimal ratio set for a fast, flowing circuit differs significantly from a tight, technical one — this design feature translates into a concrete reduction in both spares carrying costs and the time spent changing ratios between events. Over a full season, the financial and operational benefit is material.

Engine Compatibility & Bell Housings

The Albins ST6 is engineered for broad engine compatibility. Dedicated bell housings for the most popular performance engine applications are available off-the-shelf, including:

• Porsche — bell housing available for Porsche flat-six and V8 applications; ideal for 911, GT3, and Cayman-based builds
• GM LS — bell housing available for the full GM LS engine family; covers the widest range of V8 conversion and competition applications
• Additional applications — Albins maintain a comprehensive range of adapters and ancillary fitments that extend compatibility to a wide variety of engine configurations beyond those listed above

The practical result is that integrating this gearbox with your chosen engine is a predictable and well-supported process, not an engineering challenge. Please contact us with your specific engine application and we will confirm the correct bell housing or adapter arrangement.
