The Ultima 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. Complete instructions included . Ultima 6 Speed Gear sets can use the same #624107 speedometer recalibrator unit as our transmissions.
