Jesel Releases New Sportsman Steel Series Shaft Rockers
Oct
Jesel has released a new Steel Sportsman Series Shaft Rocker which has all the combined features of their Pro Aluminum Rockers with the durability of Pro Steel Rockers. Now you have a lower cost option for high stress valvetrains on a Sportsman budget.
The new rockers are black oxide coated with a .625 wide body and a lightening slot to reduce weight. These are a direct replacement for current Pro Aluminum Body Rockers without a change in pushrod length!
Available now for SBC 23°, Gen 3 Chevy (LS1/LS2/LS7), Big Block Chevy (18°,20° and 24° Conv Heads) and Small Block Fords with 20° Inline, C3, D3 and TFS Highports.
Sportsman Steel Features
Clip-Pin Nose Roller – Securely retained .520” diameter Tool Steel Nose Roller operates with less friction and decreased valve guide wear.
Tool Steel Lash Adjusters – CNC machined, heat treated alloy steel lash adjusters have been proven through years of abuse.
Centerless Ground Shafts – Precision ground and heat treated Tool Steel shaft provides years of durable service.
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 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.
