Optimum Offroad's owner Deric Schare said "I am excited to be working with Mike ,Ian & Jesse and everyone at Mendeola Transaxles to bring their over 40 years of engineering and manufacturing experience to the incredibly fast growing sport of performance side by sides".

That early transmission set a new standard in offroad racing for toughness and the team went on to win it's first of many victories the next year. Optimum Offroad based in Las Vegas, Nevada specializes in drivetrain and chassis related upgrades for performance side by sides and will be releasing a newly designed RZR gear reduction this month.
