RR Torsion Arm, Offset 2", 7/8" x 11-1/2", 600cc micro sprint

This is a heavy duty ¾" thick torsion arm.

This arm provides more offset to move the right rear bearing carrier out. This is generally needed for use with longer paddles (12" & 13"). It also depends on which Jacob's Ladder frame tab hole the paddle is mounted to.

Redesigned in 2017. The X4, X6, & X7 Hyper rear torsion arms are now designed with two shock mounting holes. The idea for the new hole, which is closer to the shackle mounting hole, was conceived when the R&D was being performed for the X7 chassis. More shock control was needed to control the rear axle when in the forward position (short wheelbase). In lieu of re-valving our shocks, we just added the new hole which adds 10% more effective shock rate to the dampening system thanks to the mechanical advantage change.

The new arm is also made a little stronger by increasing the relief pocket radius and increasing the web thickness in key areas.
