![Rocker Arm shafts, Rocker Arm Stud Kit, Head Bolt Kit and Performance Roller Rocker Arms are included in this kit
Rocker Arm Shafts
Replace broken or worn OEM pieces with stronger, more durable S&S performance parts
Direct replacement for stock parts
Hardened and surface ground for ultimate precision and durability
Rocker Arm Stud Kit
Extend the life of your cylinder heads
Prevent damage to Rocker Arm Towers
Install studs and safely re-torque nuts
Black Oxide Finish
12 pt Nuts
Head Bolt Kit
Heat Treated 8640 Steel
200,000 psi (EU: 1378,95 MPa) ultimate tensile strength
14% increases in strength over stock
Stronger material than stock Head bolts
Durable Black Oxide Coating
9/16" (EU: 1,43 cm) 12-point head with integral washer
Formed threads
Cold Formed Head
Reusable
Forged Roller Rocker Arms
Forged from 8620 steel for greater strength
Designed using Finite Element Analysis (FEA)
Rollers eliminate thrusting on valves for decreased wear on the valve train
Rocker geometry is better suited to high lift cams
Larger surface area on the thrust surfaces reduces wear on the heads
Bushings are 50% longer than stock, increasing time between rebuilds
Compatible with stock or S&S CNC heads
Oil is sprayed directly on the valve springs, reducing potential for breaking a valve due to over-heating (stock rockers tend to oil the rocker boxes, not the valves)
1.640 Ratio
Capable of .650" (EU: 1,65 cm) max Valve Lift
Serviceable and rebuildable for generations of durabilty
A must have for cams with .550" (EU: 1,40 cm) or greater lift Rocker Arm shafts, Rocker Arm Stud Kit, Head Bolt Kit and Performance Roller Rocker Arms are included in this kit
