P2 heat treated Planetary fix kit Contains (1) Machined P2 Planetary. The stock Allison 1000 P2 Planetary can strip or snap as a result of poor tuning,shock load, improperly built transmissions and higher horsepower applications and can cause catastrophic failure and/or immobility. The SunCoast P2 Planetary fix is the solution to this issue. This item is highly recommended for higher horsepower applications, including sled pulling, drag racing, as well as heavy duty towing (to accept billet P2 hub, machine work required on the P1 sun gear).
