Guardian rocker arms kit

In addition to the rocker arms themselves, this kit includes the rocker arm shafts, the rocker arm stud kit and the corresponding cylinder head bolt kit
Rocker shafts
Replace broken or worn OEM components with high-performance S&S components for greater durability and strength
Direct replacement parts for standard units
Hardened and ground surface for definitive precision and durability
Swingarm bolt kit
Extend the life of cylinder heads
Prevent damage to rocker towers
The studs must be fitted and the nuts then tightened securely
Black oxide finish
12-point nuts
Cylinder head bolt kit
In heat-treated 8640 steel
With an extreme tensile strength of 200,000 psi
14% stronger than standard
Made from stronger material than standard head bolts
With durable black oxide coating
9/16” 12-point heads with integrated washer
Specially formed threads
Cold-formed cylinder head
Reusable
Forged roller-type rocker arms
Made from 8620 forged steel for maximum strength
Designed using finite element analysis (FEA)
The rollers eliminate thrust on the valves, reducing valve wear
The rocker geometry is better suited to camshafts with high lifts
A larger surface area in push areas reduces cylinder head wear
Bushings 50% longer than standard, increasing the time between overhauls
Compatible with standard CNC-machined or S&S heads
Oil is sprayed directly onto the valve springs, reducing the chance of a valve breaking due to overheating (stock rocker arms tend to lubricate the rocker boxes, but not the valves)
Ratio of 1.640
They provide a maximum valve lift of 0.650”
Refurbishable and rebuildable to last for generations
An essential product for camshafts with lifts of 0.550" or greater
