Ultimate Honda DCT Gear Reduction
The Ultimate Honda DCT Gear Reduction is built for riders who need a serious gearing upgrade for larger tires, deep mud, technical terrain, and demanding off-road conditions. This is an all-new billet forged assembly with zero reused parts, engineered for strength, precision, and dependable performance.
The tooth profile and gear mesh have been carefully refined to deliver exceptionally smooth, quiet operation while providing the lower gearing needed for tough riding conditions. This chromoly forged and heat-treated gear set is built for increased strength, durability, and long-term reliability. Retains the factory damping design while upgrading to a precision billet aluminum hub assembly.
Fitment:
Fits 2009+ Honda 420, 500, and 520 DCT automatic ATV models.
Important Fitment Note:
Professional installation is required. Installation requires clearancing of the transmission clutch cover spacer to fit the larger gear. This can be completed by removing the spacer assembly and carefully clearancing it with a burr. Some models may require recalibrating the speed sensors. We do not recommend using auto shift mode with the gear reduction.
