I need to replace the front shocks on my Pete. I usually run 14,000 lbs. on the front axle, and closer to 18,000 when the drop axle is up. RoadKing claims to be the heaviest duty shock available but they are really expensive. Any have any experience with them? Would like to hear some actual experience before spending $700. Any other recommendations for a heavy duty shock? Been running Monroe but they get soft in 50,000 miles in my type of work. Thank you for any info or input.
