Testing out RC4WD GRU's

Out trailing on the rocks today with both Jeeps (actually drove with a controller in each hand at one point) to test out the RC4WD GRU's (Gear Reduction Units) I put in each rig. YJ is using a 45 turn and 3 to 1 GRU, the Rubicon used a 35 turn and 4 to 1 GRU. Video is currently processing but I will share it as soon as its ready. For now... a couple stills.
