Since this is a kit that will do any of these configurations, on some shocks, you may not use all of the o-rings in the kit.  This seal kit will rebuild (2) shocks.This kit comes with Viton o-rings for the shaft and IFP, which will stand up to heat and wear much better and typically only come in the "Race" series kits from King.
