Seems almost every shock absorber thread is about the brands mentioned above. I'm interested in feedback regarding shocks from KYB, Tenneco (Monroe/Rancho) or Sachs/ZF. The truck is a 2013 2500 (leafs in the rear) and I do live on a dirt road that gets washboard in spots. Ideally the shocks keep the rear axle in check without rattling my fillings loose. Any feedback appreciated.
