hit a rock under the snow in cooke city last week,and destroyed the upper and lower a arm,and shock shaft.Was considering stronger a arms,but now I'm not so sure.With everything that is wrecked the front bulkhead looks good,no damage.So the question I have is,would stronger a arms transfer more force to the bulkhead,thus more likely to wreck it also?It seems the polaris a arms take the hit,bend,but save the main structure.Does anyone have experience with this?If you have first hand experience,I feel your pain,and maybe you could help the rest of us out.It's not the first rock I ever hit and it probably won't be the last.
