Increasing the caster angle will increase the tendency of the
shock mounting screws. truck to oversteer (less traction on the rear tires, more traction
on the front tires), while decreasing the caster angle will cause
the truck to have a tendency to understeer (push in the turns).
This effect becomes more pronounced at higher steering angles
and higher spring rates. Caster is adjusted by repositioning the
shims on the pivot point of the upper suspension arms.
The stock caster setting is 7-degrees with one shim at each end
of the arm. Reduce the caster angle to 4-degrees by removing
the rear shim and inserting it next to the front shim. The caster
angle can be increased to 10-degrees by removing the front
shim and inserting it next to the rear shim.

Shock Mounting Positions
Big bumps and rough terrain require a softer suspension with
the maximum possible suspension travel and ride height.
Racing on a prepared track or on-road use requires a lower ride
height and firmer, more progressive suspension settings. The
more progressive suspension settings help reduce body roll
(increased roll stiffness), dive during braking, and squat during
acceleration.
The innermost upper shock mounting position (0) on the shock
tower is intended for use with the first generation T-Maxx

Lower Shock Mounting Positions
In the out-of-the-box configuration, the shocks are installed in
position (A) on the shock tower and position (2) on the lower
suspension arm. This setting allows for moderate suspension
travel and ride height. The more vertical position of the shocks
allows for lower shock progression and the soft, plush feel that's

The outer pair of holes on the lower suspension arm should be
used to lower the ride height of the T-Maxx, and increase the
spring force (at the wheel). This setting will improve high-speed
cornering on smoother terrain by lowering the center of gravity
and providing a firmer suspension feel. Body roll, brake dive, and
squat will be reduced.
Spring rate (at the wheel) increases as the lower shock
mounting position is moved from position (1) to position (4).
This is equivalent to using stiffer springs. Use higher spring rate
settings for flatter terrain with smaller and fewer bumps, and
lower spring rate settings for bigger bumps.
