This is 110% RC Sweat Grease. To get the most out of your RC shocks, it is important that they are smooth and consistent throughout your run, and throughout your racing weekend. One of the biggest issues is that the shock o-rings will swell up from the shock oil, which will cause your shocks to bind up, completely taking away their smoothness and consistency, and possibly costing you a win. This is a big problem. RC Sweat is a lubricant that will make your shocks silky smooth, and will also prevent the o-rings from swelling, which in turn prevents binding in your shocks. RC Sweat helps you get the best possible performance out of your shocks, which helps you give 110% on the track.
