Other things to consider:

  • Chain and chain guide clearance. G3-S Shocks are often larger in diameter than the stock units. The body end goes up and the spring goes down (as shown). This can cause clearance issues and the shock may need to be spaced outward. This may create exhaust pipe clearance problems too.

  • Tire to fender clearance is critical. There MUST always be clearance between the tire and fender at the fully collapsed point. Letter "H" above can be measured without the shock on. We recommend at least 13mm (1/2") clearance minimum as swingarms and frames flex. Tire diameters will also be different depending on the manufacturer so set the clearance with the largest diameter tire you will use. If the tire hits the fender STOP, do not pass go, give us a call and we will provide spacers to limit the travel.
