Your shock package is a very important component regarding the handling and performance of your RC vehicle. To ensure your shocks operate smoothly and without any leaks, o ring grease is applied to your shock seal/o rings. 

Udder Butter by CowRC is the absolute best grease for this application. 

Simple apply a generous coat of Butter to your seals prior to assembly and you are good to go. 

I have used many greases in the past and nothing compares to Udder Butter. The extremely rubber and plastic friendly formula plays very nice with your silicone oil. This drastically reduces swelling and increases longevity, giving a very smooth action. 

Udder Butter comes in 3 different sizes. Syringe, jar, and the  mammoth 2 pounder. 

Try it once and you will be a believer. See ya at the track!
