Tension rods control caster, anti-dive, and anti-lift in the front suspension. Caster helps determine camber gain over the suspension stroke and steering axis inclination. Caster also helps auto turn the wheel when counter-steering. The angle of the tension rod (vertical plane, front to back) also helps determine anti-dive under braking situations, and anti-lift on acceleration.
Tip: If you are using your tension rods to adjust caster more than one or two degree(s) past factory settings, there will be bind in the lower control arms traditional rubber or urethane bushing. It is recommended that you change to an aftermarket control arm with a heim joint.
