Introducting the
NovaDrive Overdrive

Demonstration model shown. Actual overdrive will vary.

When it comes to enhancing your vehicle's drivetrain, the NovaDrive Overdrive stands in a league of its own. Engineered for strength, precision, and adaptability, the NovaDrive is the ultimate upgrade for enthusiasts and professionals alike. Whether you're tackling daily commutes or pushing the limits on rugged terrain, this innovative overdrive system delivers unmatched performance and reliability. Expected availility is late 2025 after extensive testing.

Features

• Splitt Any Gear: Capable of splitting all gears, both forward and reverse. Ideal for daily use in all gears, though hard use in first/reverse gears is not recommended.


• Efficiency: Adding this 0.76:1 ratio overdrive to compatible drivetrains can greatly increase your fuel economy and drivability.


• Shifter Design: Features an internally mechanically interlocked shifter for smooth operation. Simple forward/rearward motion allows for easy integration with control cables or lever shifters.


• Unmatched Strength: Built using T18 gear geometries and tooling, acquired from Borg Warner’s T18 assets in 2022. Engineered to handle the demands of upper gears in full-size trucks, just like the original four-speed transmissions.


• Synchronized Performance: Equipped with off-the-shelf T18 blocker rings for smooth, synchronized shifting.


• Robust Construction: Engineered for simplicity, with minimal components for easy assembly and maintenance. Internally crafted from premium gear and alloy steels, housed in durable cast aluminum exteriors. Limited-edition billet housing units available on a first-come, first-served basis.


• Independent Oiling System: Self-contained oiling system, sealed from the transmission and transfer case. Compatible with the same oils used in the transmissions listed above.


• Easy Assembly: Requires transmission mainshaft replacement for installation. Designed for straightforward assembly, ensuring a hassle-free upgrade.


• Underdrive Version: The NovaDrive’s design allows for an underdrive version, though current demand focuses on extending gearing upwards due to the already low axle gearing in Jeeps. Need more torque? We’ve got a 5.3L engine for you!


• Rigorous Testing: Every NovaDrive unit undergoes rigorous in-house dyno testing, just like all our gearboxes. Real-world testing is conducted in a 1969 CJ5, followed by punishing pick-up truck trials to ensure durability and performance.


• Pricing: Designed to be economically accessible, the NovaDrive is priced competitively against alternatives like the NV4500. Estimated cost: $3,000–$5,000, with final pricing determined by production scaling.

Compatibility

• Transfer Case Compatibility: Designed with the Dana 18/20 transfer cases in mind, featuring the Texas pattern as showcased at the Expo. Versions for Dana 300 and other transfer case patterns are also available.


• Transmission Compatibility: Designed to work seamlessly with T18, SM420, SM465, and NP435 transmissions. Compatible with T90, T150, T176, and other similar units.


• Compact Design: 5.5 inches long, 10 inches wide, 12 inches tall and weighs around 60ibs. Similar in length to SM420 and NP435 adapters for Dana 18/20 transfer cases. Slightly shorter than a TH350, ensuring a perfect fit in pre-1972 Universals.


• Warn Overdrive Compatibility: Yes, but proceed with caution! Pairing the NovaDrive with a Warn overdrive may result in extreme driveshaft speeds. While we encourage experimentation (for science!), no warranties are provided for components used in such setups. Double-overdriving is not recommended for safety reasons.


• Divorced / 2WD Option: A divorced or 2WD configuration is built into the design for added versatility.
