TREMEC TR-4050 Conversion Kits for 1966-1977 Ford Bronco

No Obstacles, No Horizon Too Far - 4WD Life

TREMEC TR-4050 Early Ford Bronco

Silver Sport Transmissions has the best-engineered kits to modernize the powertrain of your early Ford Bronco. Our RestoFit® Kits bring the shifter handle to the factory-correct position for the best possible fit and our billet shifter tower provides short, crisp shifts.

Whether you plan to take your vehicle off-road, tow a camper or boat, or cruise the highway, our overdrive transmissions will help you get there.

The TREMEC TR-4050 5-Speed is the strongest 4WD transmission available on the market with a 600 lb-ft torque capacity. It's also brand new, with no remanufactured or rebuilt parts in the TR-4050. If you're stuck in the mud with your current transmission, the ultra-low 1st and rear gears can get you out of any sticky situation you have gotten yourself into! The overdriven 5th gear is perfect for the highway, reducing the NVH (noise/vibration/harshness) and improving your fuel mileage.
