6 Speed Builder kit

Product Introduction

Fits 1990 & later Big Twin 5-spd models.

Six Speed Builders kit was designed to provide a simple, low cost, 6 speed overdrive solution for 1990/L Big twin owners. These kits work in most 1990-1999 models with little or no modification. A speedometer recalibration unit is required on some 1996-2000 and all 2001 later models. These kits will work in 5 spd type 2000/Later models with additional minor modifications. The trap door is thicker than stock so any brackets used that are trap door mounted may need modification.

• Roller Detent for smoother shifting

• Precision Ground 8620 Gears and shafts

• Chrome Plated Billet Trap Door

• Gear Ratios are:

1. 2.94: 1     4. 1.23: 1
