Ultima 6-Speed Transmission Builders Kit for 1990-Later Big Twin 5-Speed & 6-Speed Models

The Ultima Six Speed Builders kit was designed to provide a simple, low-cost, 6-speed overdrive solution for 1990/L Big twin owners. Ultima 6 Speed Gear sets are the same ones used in our transmissions and are great value products. Complete instructions included or available online. Professional installation is recommended.

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.

Its trap door is thicker than stock so any brackets used that are trap door mounted may need modification. All Touring FLT and FLH Models 93/L require an oil filler spacer #89-14.

Not recommended for 2006 Softail models with the 200mm wide tire.
