The tables below describe the amounts of kick-up, change depending on the combinations of
eccentric bushings used with 0 and 1mm, 1° off set. The 0.5mm, 0.5° represent the half change.

Total caster is the angle that the C-hub is to the flat chassis bottom.
Caster is affected not only by front kick up but also by the C-hub
caster and caster eccentric bushing. The combination of all three
represents the total caster angle. The XT9 includes a 15°caster
block with the centric bushing. 1 and 2mm eccentric bushings can
be purchased as options.

The new XRAY alu front lower suspension holders provide even greater range of adjustment for the front suspension. Using different combinations of eccentric bushings, you can obtain fine adjustment of front kick-up
and roll center. For more information about the influence of kick-up and roll centers on car handling, please refer to HUDY Off-Road Set-up Book (#209099).
Eccentric bushings have two different offsets from the center.
Middle position = 0.5 mm or 0.5° from center
Outer position = 1mm or 1° from center
