I had some extra losi bladders and like said above they work fine. No more leaking out the bleeder hole. The stock bladder was in the shock body when I took the cap off. And yes I did set the bladder with a 2mm hex. Im just wondering if my savox 1258 is a taller servo and thats why the linkage is messed up with the break linkage, but I have never had a issue in other cars with it before. Greg, I agree. The shocks feel butter smooth. Some of the smoothest I have felt.
