The shocks on the SC10 should be rebuilt every month or so to keep them in top shape. Over time, the oil in the shocks will slowly leak and after a few weeks the oil loss will start to affect performance of the shocks. Also, rebuilding your shocks gives you a chance to try a new shock oil weight that could shave time off your laps.
We have a shock rebuild guide that walks you through taking apart your shocks, filling them up with fresh oil and getting them back on your SC10.
This guide walks you through changing the oil on one of your shocks. The same concept applies to the front and rear shocks.
