Serpent introduces as optional supershort SS-RCM shocks for the Serpent 747 combined with lower shocktowers.
The Serpent designed SuperShort RCM shocks, do NOT require new shock-springs. You can continue to use the shockabsorber springs you have always been using.
The volume of the shocks has also remained the same as before ! The shortening has been achieved by a lower cap, a shorter seal-pack and lower balljoints mainly.
The SS-RCM shocks are about 4.5mm lower than the current shocks, so the shocktowers are lowered at same rate, to lower the center of gravity even more.
To make the upgrade you need:
804305 Shocktower carbon 747 FR low
804306 Shocktower carbon 747 RR low
160124 Shock set RCM-SS (2) x 2
Depending on the version of wishbones you are using, you may need to grind a small area on the wishbone, where the spring-cup may touch. Otherwise no further mods are needed and assembly is easy !
