Associated Vented Slipper Pad
Associated has released these new vented slipper pads that feature a fan pattern of 1.5mm holes that allows for cooling and more consistent slipper performance. These parts were used by Ryan Cavalieri and Ryan Maifield at the 2011 Reedy Race of Champions and Cactus Classic events. A pack includes a pair of pads and they will fit the B4.1 FT, SC10 FT, T4.1 FT, B44.1 FT, SC10 4×4, as well as any B4, T4, B44 and SC10 with the addition of #7486 V2 slipper spring and washer.
