There are two different rocker arm sets that are compatible with Slayer.  
Both sets will allow the wheel to travel a total of 60mm in the vertical 
direction.  From the ride height position, the wheel will be able to travel 
40mm in the upward direction (bump), and 20mm in the downward 
direction (droop).  The Slayer comes equipped with the Progressive 2 
rocker set, which offers a good balance of progressive rate for predictable 
body roll, brake dive, and high-speed stability.

The Progressive 3 rocker arm set (available separately) uses a higher 
progressive rate that will provide a firmer feel, reducing body roll, brake 
dive and rear squat.  Installation of the Progressive 3 rocker arm requires 
the following parts:
#5359 Progressive 3 Rocker Arm Set
#5133 Pushrod Spacers (these are required to lengthen the pushrods to 

maintain proper suspension travel.)

The chart below demonstrate the effect of the various rocker arms on 
wheel force as the suspension is compressed. On the progressive rate, 
wheel force is light at first and increases as the suspension is compressed.

Bump Steer Elimination Chart

The illustrations and the following table detail the position of the outer 
toe link end for various caster and roll center settings to eliminate bump 
steer. The shims and the hollow balls used to adjust bump steer are 
provided with your vehicle.

Rear

When the rear upper control 
arms are mounted in the lower 
of its two mounting holes in  
the bulkhead (roll center), the 
tall hollow ball should be used 
as shown.
