Since their release, Jesel Sportsman Series shaft rocker arms have proven themselves to be the ultimate replacements for inadequate stud rocker assemblies on OEM and aftermarket cylinder heads. The 2024 aluminum bodied rocker arms are designed to withstand open spring pressures of up to 900 lbs., while maintaining precise valve lash settings. They are designed to bolt on with little to no cylinder head modifications and in most cases still fit under a stock valve cover. The rocker geometry is preset and engineered using the common valve supplied with the specific cylinder head to provide a bolt-on-and-go installation. If you're still spending aggravating hours adjusting your stud rockers only to have to repeat the procedure the next weekend, Jesel Sportsman Series shaft rocker arms are your solution. Choose a set designed for your application.

Special parts often require special tools. Jesel's pushrod length checking tools are one of those "getting it right" tools for pushrod length checking. The basic body of the tool consists of three pieces of aluminum tubing. The tubing pieces are 5 in., 3 in. and 1.5 in. long. On two pieces of the tubing, one end is male and the other is female and each end is threaded. Outer ends accept a screw-in pushrod ball end. In total, the pushrod length checking tools are adjustable from 6 in. to 12 in. Important note: Before you order new pushrods, first check the pushrod length on several different cylinders, as well as on both engine's cylinder heads to determine sizes. Never rotate valvetrain using the pushrod checker tool.

Jesel camshaft bearings incorporate a lead-based alloy Babbitt material that's 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. Order the bearing size needed for your application.

Jesel Extreme Series distributor drive kits were introduced in 2011, and are designed to handle the high cylinder pressures experienced in Pro Stock and Pro-Mod type engines. They feature MSD 5 in. Pro-Caps to ensure accurate spark delivery, as well as to reduce spark scatter frequently experienced in high cylinder pressure applications. Jesel belt-driven distributor systems are direct bolt-on accessories to their camshaft belt drives, eliminating timing inaccuracies due to camshaft deflection and cam walk. By driving the distributor drive directly off the camshaft pulley, ignition timing stays constant and will not deviate from the initial settings. Plus, Jesel Extreme distributor drives provide the ability to set the engine back further in the chassis without worrying about firewall or windshield interference.
