I bash dirt only slash 4X4 Castle mmp sct 3S. Finally broke down and bought a set of split six bead locks with gladiators and strc aluminum rings. I LOVE EM. Not a single problem and I beat the heck out of em. I did tape my tires as I was tired of ballooning and used a SMALL amount of silicone inner and outer. Went through 4 packs with out a problem. Got a set of unmounted trenchers will be here tomorrow and will tape and mount for a comparison test. So far Pro Line bead locks rule. I completely destroyed a GOOD set of trencher pre mounts trying to boil them to get the tires off to put on the bead locks.
