RTS Transmission, Planetary 4 Pinion, Fully Rollerised, Torrington Bearings, C4 C5 C9 C10, Automatic, Each - RTS-4PPC4

Part Number: RTS-4PPC4

RTS 4-Pinion Front Planetary The standard oem front planetary is another weak link that needs some attention when trying to make the C4 transmission survive in a performace environment. The original design planetary has only 3 gears and does not include any bearings, which in turn generates a lot of heat, making it prone to failure. Our new 4-pinion planetary has 4 gears instead of the oem 3 for extra strength while also adding bearings on each of the 4-pinions and thrust shims to reduce premature wear and friction within the gearbox. This will therefore reduce the heat generated in the transmission, increasing the efficiency of the system (less HP loss) while also reducing transmission oil temperatures (which is the transmissions worst enemy)! All these features are incorporated into a 4140 Chromoly CNC-machined housing with 8620 heat treated steel helical gears held in place with Chromoly pins which are deep hardened to HRC60-65. Many people believe that the 6 pinion version is the best unit to buy, which is not entirely correct. 6 pinion planetaries are heavier, take more power to drive and the housing strength is compromised to accomodate the extra gears. RTS has looked at all the pros and cons of these designs and settled on manufacturing the 4 Pinion version as being the best choice for your race winning transmission. RTS-4PPC4-TB Torrington bearing is also available as a service part sold individually Note: Most transmission builders are well versed on the importance of oil feed for bearing survival, we can only do so much when making quality transmission components and rely on builders doing their part in assembly practice.
