TCI® GM TH400 6-Pinion Planetary Set (2.10 1st/1.40 2nd)

[CPG Marketing]

New planetary set from TCI® reduces starting line spin commonly found in high horsepower turbo, supercharged & nitrous injected GM TH400 drag racing applications

When it comes to high horsepower and limited tire size in drag race applications where the more durable GM TH400 transmission is needed, tire spin has always been an issue. Turbocharged, supercharged and nitrous injected engines can simply product too much power for the standard GM TH400 2.48 1st/1.48 2nd gear ratios. To counter this problem, engineers at TCI® have developed a 6-pinion planetary set that improves take-off power and maximizes racing performance by decreasing the starting line gear ratio by 15 percent to 2.10 1st/1.40 2nd.




This unique planetary set features a 6-pinion rear carrier for increased load capacity and longevity (load capacity increased as much as 17 percent). The higher first gear ratio decreases the intensity of the initial launch for reduced tire spin. In addition, the heavy-duty planetary construction is a CNC-machined billet carrier that provides a more concentric gearing system for improved performance and bullet proof durability.

With the ability to decrease tire spin, starting line traction is maximized, making this planetary set a must have for high horsepower drag racing applications, especially those utilizing turbocharged, supercharged or heavily nitrous injected engines.
