SUSPENSION

Front Rear Scissor Stop (FRSS)

The purpose of the front rear scissor stop (FRSS) is to control the bump attitude

of the rear suspension. As the front torque arm (FTA) hits the bump, it forces the

rear scissor to collapse a predetermined amount, depending on the FRSS block

position.
This accomplishes two important things, it allows a lighter spring rate on the FTA

because it can borrow spring rate from the rear torsion springs; and it prepares the

rear portion of the suspension for the bump.
The FRSS is made of a resilient material allowing smooth action and preventing

any suspension component damage.
This unique feature is applied to the Xtra-10 and Xtra-12 rear suspensions. Pat-

ents are pending.

Rear Scissor

Front Torque

Arm (FTA)

FRSS with short (low) leg to rear. Note the FTA goes down lower

before rear scissor begins to collapse.

Rear Scissor

Front Torque

Arm (FTA)

FRSS with long (high) leg to rear. Note this forces rear scissor to

collapse with less FTA movement than when in short position.
