Complete pre assembled long RCC shock absorbers. Comes with optional 1, 2 & 4 hole pistons. The 2009 version RCC-X has a better seal / support package. The shockrod is supported better with the delrin bushing, and a new design x-ring, made of a special silicone rubber (instead of an o-ring) provides a better seal at less friction. A new mould for the nylon parts has been made, so also the nylon parts of the shocks are improved, both pistons and ball-joints too. Supersmooth shocks ! Fits all 1/8 and 1/10 gas-cars, but also 1/10 electric touringcars.
