Triumph Spitfire Gear Box
The Triumph Spitfire gear box represents one of the most critical mechanical systems in your classic British sports car. At Rimmer Bros, we understand the precise engineering that makes these transmissions work smoothly, whether you own an early 3-rail or later single-rail configuration.
Your Spitfire's transmission requires specific attention to maintain the crisp gear changes that define the driving experience. We stock both genuine and high-quality aftermarket components for all Spitfire models, from the Mark I through to the 1500. Our extensive inventory covers everything from complete gearbox rebuilds to individual synchromesh rings and gear sets.
The evolution from the early 3-rail gearbox to the later single-rail design brought improved reliability and smoother operation. Understanding these differences is essential when sourcing the correct parts for your restoration or maintenance project.
Our parts advisors possess decades of combined experience with Spitfire transmissions. They understand which components wear first, how to identify early warning signs of gear box problems, and which upgrades can improve performance and longevity. This knowledge ensures you receive exactly the right parts for your specific model and year.
