The 5 Speed gear box has actually been around for a few years but the growing number of modifications has created a lot more interest in it. In addition to close ratio first gears, Andrews Products also makes replacement gears for 2nd., 3rd., 4th. and 5th. gear sets. As with the close first gears, all 5 Speed gears are made from high nickel alloy and heat treated and shot-peened to give maximum durability and strength. Also, where applicable, lead-in ramps have been machined into most gears to improve shifting and reduce wear on drive dogs and drive slots.

Note:
If these gears are installed in 1994-2006 models, gears must be installed in pairs (mainshaft & countershaft gear).
