The Roltek 4 speed is a 6 Lug dog ring modular 4 speed. It is manufactured and designed by Borerite Inc. Since it is designed for road race applications, It is not synchronized and uses a spur gear design. It uses the same 6 lug dog rings found in our JT5 Enduro 5 speed. It is based on the T-10 4 speed and uses the standard GM 26 spline input and 32 spline output configuration along with a GM bolt pattern. It can be used with Hurst or Long shifters. These are assembled and "blueprinted" by us in our shop in Tequesta, Florida.
