Jesel Pro-Series Shaft Rockers - SB Ford - TFS High Port
Designed for Trick Flow Specialties small block Ford High Port inline valve cylinder heads with .100"-.040" offset valve centerlines and higher rocker ratios. Allows for more rocker to valve cover clearance. Used with high ratios requiring a 1.650" rocker pivot length.
Walk through the pits of any professional racing event and you will be hard pressed not to find a JESEL Pro Series rocker arm system controlling the valvetrain. For over 30 years, championship winning racers in virtually every form of racing from NHRA Pro Stock to Sprint Cup rely on JESEL shaft rockers to get them into the winners circle. Used by top engine builders worldwide, JESEL rockers continue to set the standard by which all others are measured.
The excellent mechanical properties inherent to our custom blended aluminum alloy allows for the design of an extremely durable and lightweight valvetrain assembly. Tensile strength of our custom blended alloy at 300° far exceeds that of the less expensive, industry standard alloys. Low moment of inertia along with FEA designed bodies insures that lobe lift is not wasted due to rocker body deflection.
The Pro Series rocker systems are built and custom manufactured to your specifications. 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 if needed to compensate for longer than stock valve lengths.
HIGH RATIO ROCKER BODY OPTIONS
Standard Slot
1.650 Pivot BB Rocker / Weight: 202g
Our default lightening program. Provides for a stiff body capable of controlling the valvetrain at high RPM.
Optional Solid Body
1.650 Pivot BB Rocker / Weight: 210g
Our strongest rocker body. Intended for use with high cylinder pressure applications such as nitrous and blowers.
Optional MoHawk Beam
1.650 Pivot BB Rocker / Weight: 195g
Our stiffest lightweight body. Lowest moment of inertia ideal for extremely high RPM valve control and extended spring life.
CUSTOM BUILT TO YOUR SPECIFICATIONS
Standard Shotpeen Surface Finish
Induces an even, compressive stress layer in the surface of the rocker body. Increases the resistance to fatigue failures. Adds compression strength and stress relieves rocker body.
Optional Needle Roller
Recommended for use with high lift, high spring pressure applications. Prevents the roller from stalling and skidding across the valve tip. Highly recommended when using .312" or smaller valve stems.
Optional Ball Adjuster
Has less friction than cup type adjusters. Makes rocker arm stronger by increasing the adjuster thread area and eliminates counterbore area.
Optional ARP Shaft and Stand Bolts
Manufactured from ARP 2000 material, these bolts can be torqued to 35 ft lbs and are recommended for spring pressures exceeding 800 lbs. open.
