Review TRIUMPH Spitfire Speed Gearbox Reverse Gear fits TR7 TR8

The Triumph UKC8750 gearbox is a high-performance replacement gearbox specifically designed for Triumph TR7 and TR8 models, as well as the Spitfire MkIV. This gearbox is an essential upgrade for those seeking superior power transmission and reliability from their classic Triumph vehicles.

The UKC8750 gearbox boasts several key features that set it apart from the original equipment. First and foremost, it comes with a reverse gear, making it a more versatile option than the standard TR7/TR8 gearbox. The reverse gear is engaged through a remote lever, providing a more ergonomic and convenient shifting experience.

The gearbox housing is manufactured from high-strength aluminum alloy, making it both lightweight and robust. The synchromesh system has been upgraded for smoother and faster gear changes, while the gear ratios have been carefully selected to optimize power delivery and improve overall performance.

The UKC8750 gearbox also benefits from improved cooling, with larger oil cooler hoses and an expanded cooling system. This helps to reduce the risk of overheating and ensures that the gearbox operates at peak efficiency, even during prolonged periods of heavy use.

The gearbox comes with a new clutch assembly, featuring a heavier clutch plate and a high-performance clutch pressure plate. This results in improved clutch engagement and a more positive feel at the pedal, making it easier to control the vehicle's power and acceleration.

The UKC8750 gearbox is designed to be a direct replacement for the original TR7/TR8 gearbox, making installation straightforward and hassle-free. It also comes with all necessary new seals and gaskets, ensuring a leak-free installation and a reliable seal between the gearbox and the engine.

In summary, the Triumph UKC8750 gearbox is a top-tier replacement gearbox for Triumph TR7, TR8, and Spitfire MkIV models. Its reverse gear, upgraded synchromesh system, improved cooling, and high-performance clutch assembly make it a must-have upgrade for any enthusiast looking to maximize the potential of their classic Triumph vehicle.
