⚙️ Fresh build. Proven parts. Ready for the road.
This freshly rebuilt **5-speed rod-change gearbox** is headed under a customer’s fresh 1275 engine build. 💪
We upgraded it with a **cross-pin differential** for added strength and reliability, then finished the case with a vibratory polish for a clean factory-inspired look.
At **Boot2bonnet**, we don’t just sell parts—we install them every day in our own workshop. The bearings, seals, gears, differentials, and components we recommend are the exact same parts we trust in our customer builds.
That means when you order from us, you’re getting parts that have been proven in real-world restorations and performance builds—not just pulled off a shelf.
Whether you’re tackling your own gearbox rebuild or a complete restoration, we’ve got the parts and the experience to help you get it right the first time.
