Product Details
The Honda OEM 4.7 Final Drive Set is a genuine factory transmission component designed for select Honda and Acura K-Series manual transmissions. This complete countershaft and ring gear package features a 4.764 final drive ratio, making it an excellent option for transmission rebuilds, performance upgrades, and K-Series drivetrain conversions.
A shorter final drive ratio increases torque multiplication at the wheels, helping improve acceleration and throttle response. The 4.7 final drive is a popular choice for naturally aspirated K-Series builds, track cars, and performance street applications where quicker acceleration is a priority.
Manufactured to Honda's original equipment specifications, this set provides factory-quality construction, precise gear engagement, and dependable durability.

- Genuine Honda OEM Part: Factory-quality construction and precision fitment.
- 4.764 Final Drive Ratio: Popular 4.7 gearing for K-Series performance applications.
- Complete Matched Set: Includes the countershaft and matching final drive ring gear.
- Improved Acceleration Potential: Shorter gearing provides increased torque multiplication compared with taller final drive ratios.
- Precision-Machined Gears: Designed for proper gear engagement and reliable operation.

I just remember when piecing together parts for my build, a lot of NA time attack car setups and other all motor setups etc were using a 4.7 final drive. I watched YouTube videos and it just made it seem like every gear revs out quicker. I didn't know what to expect truthfully but after getting to know my car again since the transmission build, it honestly does feel like every gear is shorter and more aggressive.

Love the acceleration of gears 1-5 with this thing paired with the TSX 6th gear. Great customer service by KSP as always.

I don't know how the original failed, but it did. Of course, this genuine Honda part works perfectly, especially with the Wavetrac Limited Slip Differential. To the next 140,000 miles!

Great product, quicker acceleration compared to the 4.3 final drive...great upgrade for those who have 02-04 rsx-s, I dont have TSX 6th gear it's not bad at all
Andrew Steele | June 13th, 2011
Great Product. Noticeable difference from the 4.3 in my 04 RSX. I would recommend using the TSX 6th gear if you spend time on the interstate.
