Sweet, ran my truck to test the shocks with some of Mantiswork's custom pistons and they felt amazing. Im not sure what oil wt was in it, but the truck felt so good. since I am waiting for some different o-rings, and the stock ones arent the greatest, he put some caster o-rings he had on hand. with the custom pistons the rebound rate was so much improved, the truck looked as if it was gliding over the ruff parts of the track.
