Reverse wound direct clutch pack spring for the 904, 998, 999, 500, 42RH, 42RE, 44RH, 44RE. The stock spring in the direct clutch drum loses its tension at high RPM and causes the direct clutches to drag in 1st gear. This spring is wound in the opposite direction which eliminates that problem and keeps the clutches from burning up and also helps eliminate 2-3 shift overlap. This spring should be used in any transmission that will see 5500 RPM or more. This is a direct replacement for the stock spring, no other parts or modifications are necessary. These springs have been through a shot peening process that drastically increases cycle life and they are 100% made in the USA. $30 plus shipping.
