Without a doubt it is Dan Jesel. Dan is the driving force behind all that JESEL does. He is constantly coming up with innovative ideas such as the MoHawk rocker, low-friction ball-type adjusters, lightweight Keyway roller lifters and belt drives that will survive a 500-mile NASCAR race, or 24 hours at Le Mans. More recently he designed and patented the double roller cam followers for the Modular Ford and Ecotec overhead cam engines. Subtle design features such as the “nested” rollers in the Ecotec followers are classic JESEL innovation. Dan's latest projects include valvetrain systems for race and hot street V-Twins and a valvetrain for NASCAR racers that is stable in excess of 11,000rpm. How does all this come about? Dan and his engineers spend thousands of hours designing and testing parts in JESEL's R&D center, which includes 2 state-of-the-art Spintron machines and a Superflow dyno to validate new concepts and test components for durability.
After nearly 40 years of racing and designing valvetrain components for serious racers, I’ve never been more excited about what is going on at JESEL. With our new state-of-the-art facility and staff of top-notch engineers, we are now positioned to quickly develop new products designed to keep you ahead of the competition. Much of our motivation comes from the support and validation of our products by the racing community. When I see champions like Greg Anderson, Kevin Harvick and Dale Earnhardt Jr. run our parts, it is extremely gratifying knowing that we are successful at the most demanding levels of racing. But I’m even prouder of our dominance in the sportsman ranks. At this year’s NHRA US Nationals approximately 90% of the Competition Eliminator qualifiers, and 73% of Super Stock qualifiers used our shaft rockers and belt drives. I think that this is a strong testimony that we build affordable, quality components that sportsman racers can depend on race-after-race.
A few more reasons why I’m looking forward to the next 10 years are the huge technological breakthroughs in machinery, exciting new materials, and sophisticated test equipment. We’ve just scratched the surface of what will be possible in the future. However, none of our success – past, present or future – would be possible without our people. JESEL’s success has been a team effort by many talented people. Though we’ve grown considerably over the past few years, one of our biggest strengths is that we think and act like a small company. We treat every order as a custom order, and we service our customers one at a time.
It’s safe to say that JESEL is the originator of the modern racing belt drive system. Like most JESEL valvetrain components its belt drive was born out of necessity as NASCAR racers were experiencing frequent timing chain failures in 500-mile races. It has been refined over the years to a precise timing system that is durable enough to endure tough 24-hour races such as Daytona and Le Mans or a full-season of circle track competition. Racers have been rewarded with years of service from their JESEL belt drives by simply replacing the belt at recommended service intervals. Besides being more durable than gear or chain drives, JESEL’s belt drive systems offer a number of advantages.
Built to last. Built to win. Every JESEL belt drive system is built using the finest materials and coatings available, and is machined to precise tolerances in JESEL’s state-of-the-art CNC machining centers. Check out our unmatched key features.
