| || Sportsman Series Shaft Rockers |
Still putting up with adjusting your stud rockers every weekend? Racers and engine builders around the world have been rewarded with years of reliable, trouble free service from their Jesel Sportsman Series Shaft Rockers on countless applications from daily drivers to drag cars, marine applications, dirt and asphalt oval track racing.
| || PRO Series Shaft Rockers |
Jesel Pro Series Shaft Rockers come in thousands of combinations. Anything from rocker ratio to adjuster offset to lightening options can be tailored to your specific needs. A shot peened surface finish along with a profiled rocker tail and a clipped-pin nose roller are standard features found on the Pro Series kits. Even the rocker stands can be custom ordered.
| || PRO J2K Series Shaft Rockers |
The ultimate balance of mass, stiffness and strength, Jesel Pro J2K Series Shaft Rockers are the top choice for NHRA, Sprint Cup, Nationwide and Craftsman Truck Series engine builders. These MoHawked rockers are so strong that we have been able to supply NASCAR teams with rocker ratios of up to 2.3 to 1.
| || Camshaft Belt Drives |
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.
| || Zero Thrust Cam Adapter |
Introduced in 2000 and proven in NASCAR and NHRA racing to reduce lifter damaging camshaft endplay.
| || Jesel White Rhino Belts |
Jesel White Rhino Belts are the future of camshaft belt drives. Created from EPDM compounds, they are designed to be up to 10-times more durable, and provide longer life at higher temperatures than traditional belts.
| || One Piece Upper Pulley Belt Drives |
For engine builders and racers currently running chain or gear drives, Jesel now has a cost effective alternative Camshaft Belt Drive. This drive features a solid, one piece upper pulley design that offers cam timing adjustability of ± 8°. Proven standard features such as a 25mm reinforced High Torq Drive™ belt, bronze thrust washers and high vacuum Teflon® coated cam and crank seals will reward the racer with years of dependable service. Camshaft belt drives reduce oil windage, they are significantly stronger than timing chains and are gentler than gear drives on the valvetrain.
| || Distributor Drives |
The Jesel Belt Driven Distributor eliminates timing inaccuracies due to camshaft deflection and cam-walk. A typical distributor driven by the cam gear has a history of retarding the timing at high RPM due to the camshaft twisting from torsion loads. The Jesel drive, when used in conjunction with a crank trigger and external ignition box, provides the engine builder with an accurate ignition system that does not deviate from the initial setting. It also eliminates any firewall or windshield interference and allows the engine to be set back further in the chassis. The addition of this drive allows for quicker intake manifold changes and more efficient plug wire routing. This drive can be used with a wet sump oiling system with the addition of a gear driven distributor plug sold separately.
| Front Drive Combos |
For those racers who run both Camshaft Belt Drives along with the Jesel Front Mount Distributor, Jesel offers a Front Drive Kit that incorporates the two units into one convenient part number. This value packed combination is available for our most popular applications and requires the use of a crank trigger style ignition system.
| || TS-Series Keyway Roller Lifters |
Jesel's TS Series Keyway Roller Lifters have been redesigned with additional standard features and new materials. With over a decade of continuous development and improvements in the Keyway Series, Jesel's fully re-buildable TS Series Keyway Roller Lifters are assembled with taller tool steel bodies for added support, longer needles to better distribute load, and a REM polished DLC coated body. Lightweight design, low friction and proven durability make Jesel Keyway Roller Lifters the gold standard wherever peak performance is required.
| || Nitro-Alcohol Hemi Lifters |
Jesel’s direct replacement, ultra strong, Nitro-Alcohol Hemi Lifter is resetting the standard for lifters in blown nitro and alcohol engines. The REM polished, one-piece tool steel bodies are connected with a heat treated stainless steel tie bar and can be fully rebuilt. Roller features include precision sorted tool steel needles distributing the load to a .378” diameter dual pinned axle and are available in .905”, 1.000”, 1.062” Open Pocket or 1.062” Full Body Diameters.
| || Solid Body Lifters |
New for 2009, this solid body, tie-bar design steel lifter is a perfect fit for sportsman and professional racers in every type of racing venue. Whether you are into drag racing, circle track or if you’re just running a serious piece on the street, this lifter was designed to be a cost effective alternative to our TS Series lifters. Ultra smooth REM polished heat treated bodies, featuring pressurized oiling and precision sorted needle bearings, are CNC machined and held to tolerances far exceeding current industry standards. Available in .842”, .875” and .905” diameter bodies, we have applications for all popular race and O.E.M. blocks.
| || Tie-Bar Roller Lifters |
Jesel's Tie-Bar Roller Lifters may look like all other tie-bar lifters, but don't be fooled - these Tie-Bars have it all -- fully pressurized internal oil circuits, tolerances held to ±0001”, hard-coated steel lifter bodies, internal-locking axle pin, aluminum pistons with hardened steel pushrod seats and a tie-bar made out of tempered stainless steel. The only difference between Jesel's top of the line Keyway Roller Lifters and its tie-bars is the alignment device and the easy drop-in installation that makes tie-bars so popular.
| || Dog Bone Roller Lifters |
Dog Bone Roller Lifters get their name from the O.E. style dog bone shape alignment plates that are bolted to the cylinder block for cam/roller alignment. Jesel's Dog Bone Roller Lifters are lighter than traditional tie bar styles of lifters and can be easily installed in the home workshop using Jesel's Dog Bone Installation Fixture. These roller lifters are ideal for most forms of racing, available in lifter diameters of .842”, .875”, .905” and .937”. Rollers come in .760”, .785“, .820” and .850” diameters (dependent upon body diameter). Standard Jesel features include full internal oil circuits, hard-coated steel bodies, and aluminum pistons with hardened steel (centered and offset) pushrod seats.
| || Bronze Lifter Bushings |
Jesel's bronze lifter bushings are the most durable on the market. They are CNC-machined to exacting tolerances out of high-strength A-45 bronze material. Several styles and sizes are available to accommodate most applications.
| || Ford Modular & Esslinger Overhead Cam Followers |
Racers have found that the standard OEM cam followers just can’t stand up to extreme RPM and loads from increased spring pressure, supercharging and fast lift cams. Jesel's Ford Modular 2v, 3v, 4v and Esslinger Steel Double-Roller Overhead Cam Followers operate with less friction by featuring a needle bearing roller on both the valve tip and camshaft to eliminate scrubbing and galling. Available for OEM hydraulic lash posts or Jesel’s solid lash posts.
| || GM Ecotech Overhead Cam Followers |
Track tested and proven, these CNC machined heat treated alloy steel cam followers are designed to withstand the increased RPM and spring loads used in high performance EcoTec race engines. The patented nested needle bearing cam and valve tip rollers reduces friction and prevents galling of the valve tip. Available for OEM hydraulic lash posts or Jesel’s solid lash posts.
| || GM Ecotec / Ford Modular / Esslinger Lash Post Adjusters |
Jesel has designed these adjustable solid lash posts to work in conjunction with our overhead cam followers. Each heat-treated, precision ground post is supplied with an assortment of shims to adjust for proper valve lash. The tip of this post is designed to stay engaged into the body of the cam follower. This lash post is available with extended tips for small base circle cams.
| || Modular Pushrods |
Jesel’s 2 and 3 piece premium Pro Series Modular Pushrods completes the Jesel Valvetrain System. Featuring tapered tubing for the ultimate in strength and intake port clearance, racers can now order custom lengths and tip designs, or build their own. Another Jesel innovation is the substitution of ball-end adjusters in place of cup-adjusters for stronger, lighter rockers and reduced valvetrain friction. Jesel offers a full line of cup and ball tip styles for its Modular pushrods. Now you can order your entire valvetrain from one source, with the confidence of knowing your pushrods are compatible with Jesel shaft rockers and roller lifters, and meet the exacting standards of all Jesel products.
| || Tool Steel Ball Lash Adjusters |
Jesel's Tool Steel Ball Lash Adjusters not only operate with less friction than a conventional cup type adjuster, but by eliminating the counter bore needed for a cup style adjuster, it increases the strength of the rocker by adding needed thread contact area. Jesel offers the Ball Lash Adjuster in two diameters, a 5/16-24 thread and a direct cup style replacement 3/8-24 thread. The 5/16" thread adjuster without an internal oil circuit provides for the strongest and lightest rocker assembly possible.
| || Modular Cam Gears |
Jesel engineered this Modular Cam Gear assembly to provide the engine builder with an accurate way of setting the ignition timing. By manufacturing the gear separate from the camshaft, it can not only be replaced if damaged, but can also be ground to exacting tolerances and heat-treated to the proper specifications. This slip-fit precision ground gear, when attached to a precision ground camshaft snout, eliminates run-out typically found on traditional “machined-on-the-cam” gears.
| || Coated Babbit And NeedleCam Bearings |
Jesel's Babbitt camshaft bearings incorporate a lead based alloy babbit material that is applied to a precision centerless ground seamless steel back. This Babbitt material, in conjunction with a dry-film polymer lubricant, protects the bearing surface from damage due to instances such as cold starts, low oil flow and catastrophic loss of oil pressure.
In an effort to reduce oil windage and oil aeration from the camshaft, Jesel offers encapsulated needle-bearing camshaft bearings for a 50 to 70mm cam core. The low friction rollers are designed to operate with a minimal supply of oil. If you will be running a belt drive with this bearing, provisions need to be made to supplement the oil supply to the thrust washers of the belt drive.
