700935 Offset Primary Kits for Evolution Big Twin 1991 1999 Dyna Tw

This Zodiac primary offset kit is engineered for models where the transmission cannot be moved independently. It allows for primary offsets of 12mm to 55mm, facilitating the installation of wide rear tires. The kit features a transmission main shaft and 5th gear CNC-machined from high-stress 20CrMnT gear steel, tempered to a core hardness of 35-45 Rockwell. Each kit includes a primary spacer ring, extended crankshaft extension, main drive gear with needle bearings, and all necessary hardware. Manufactured in Europe by Zodiac, these components ensure the transmission housing remains centered while providing the clearance needed for aggressive custom wheel and belt configurations. It is a comprehensive solution for maintaining drivetrain alignment in wide-tire builds.
