There are a couple of types of shocks that work well for "street" trucks. The common two tube, low pressure type of shocks that are supplied as OEM equipment, are available in upgraded versions. Monroe has many variants that feature fluid reservoirs that are almost double the OEM specifications in their "Magnum" and "Sensatrac" series. These are relatively inexpensive shocks and are quite reliable for street and towing usage. A heavier duty shock is a high pressure gas charged monotube design. These are rugged units and will hold up better to the constant pounding of rough roads, and heavy trailer loads. They won't fade as quickly as the two tube reservoir designs when they heat up. They commonly feature nitrogen pressures of 200#-300#, and have a smaller fluid reservoir than the larger two tube design. The Bilstein "Heavy Duty" shocks and the Monroe "Reflex" series share the monotube gas charged construction. These are upscale shocks that will give an excellent ride under varying conditions, and especially shine when the road becomes rough and the loads are heavy. Most OEM shocks are shot before the owners realize they are worn out. Most will need replacement before 50K are reached, sooner with bad roads and heavy trailers. It is wise to check them every so often. You might be surprised to find the rebound restriction has failed. If your truck doesn't corner as well, bounces after the bump, and mushes under a load, chances are they need replacement. Gard |
