Similar innovation has been incorporated in JESEL's roller lifters pressurized
internal oil circuits, exotic metals, proprietary coatings and machined tolerances
held to ± .0002" are just some of the technology packed into JESEL roller lifters.
They are simply the lightest and strongest roller lifters on the market. The same
goes for JESEL belt drives. New belt drives come on the market every day
surrounded by wild claims. But when it comes to the serious business of
winning racers and chasing championships, more Nascar and NHRA Pro Stock
teams depend on JESEL'S proven technology than all other makers of valvetrain
products combined.

JESEL Innovation

What makes JESEL different than other valvetrain companies? Without a doubt

it is Dan Jesel.Dan is the driving force behind all that JESEL does. he is

constantly coming up with innovate 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 Ecotech overhead cam engines. Subtle design features such as the "nested"

rollers in the Ecotech followers are classic JESEL innovation. Dan's latest

projects include valvetrain systems for race and hot street Harleys and a

valvetrain for NASCAR racers that is stable in excess of 11,000 rpm. 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 a state

of the art Spintron machine and a Superflow dyno to validate new concepts and

test components for durability.

Why JESEL ?
A large part of the JESEL innovation story is how JESEL valvetrain components

are made. It starts with the quality control room that inspects raw materials

as they come through the door. A Beckman SS VI Spectrometer tests the

chemical makeup of metals down to parts per billion. Optical

microscopes are used to examine the microstructures of alloys, and micro

hardness testing is done to accurately check the surface treatment of steel

alloys. JESEL takes its quality of raw materials and heat treatments very seriously.
After the raw materials pass this tough inspection process they are machined

into finished products on the most sophisticated CNC machines avauilable. Rigid

inspection techniques are used for quality control such as the Optical Comparator

Microscope that is a true stereo (simultaneous dual image) comparator microscope.

This digital imaging system is used primarily to inspect the radiused surfaces of

pushrods and adjusters, but can be used for any type of silhouette projection

and coordinate measurement. These extreme checks and balances ensure that

race teams will not experience failures due to variances in materials or machining

processes. Because JESEL uses the most advanced CNC machines available

its production capability is the most efficient in the industry, bringing prices

down to affordable levels for the highest quality parts. When you realize all

of the engineering and quality that JESEL builds into its products, it's hard to

argue against their value, and the peace of mind that comes from using

championship proven components.
