The Infinity Battery Strap for the Serpent Spyder SRX-2 MM buggy is a direct replacement for the stock battery strap, installing with kit thumb screws. This battery strap allows for slightly more chassis flex when compared to stock, and also makes battery changes quicker and easier. The Infinity straps include holes to use the stock plastic standoffs for holding "shorty" lipo batteries, and slight indents to dodge battery plug locations. These cool little carbon fiber straps set your Spyder apart from the other Serpents in the pits!
