NP435 Transmission & Adapter Kit - 1966-77 Ford Bronco
The NP435 is a legendary heavy-duty 4-speed manual transmission manufactured by New Process Gear. Known for its cast-iron case, robust construction, and extremely low first gear (approximately 6.69:1), the NP435 has long been a popular choice for rock crawling, off-road use, and heavy-duty applications. When paired with this adapter kit, it becomes a highly capable upgrade for 1966-77 Ford Broncos seeking improved control and low-speed torque.
This kit includes the components needed to install an NP435 transmission into your Early Bronco, providing a strong, reliable drivetrain configuration suitable for demanding terrain.
