As our followers know, we try to feature the more unusual. Though many trucks may be more restored and close to a trophy at a show (which is great).  But we look for those more unique and are really seen.  This month is no exception!  Most of these tilt cabs are lost in the past! Probably worked until they were...

Prior to WWII rubber was not of quality to withstand continual contact with petroleum based lubricants. Because it had never existed, the auto and truck factories used the materials available. An excellent example of this is grease seals used in early vehicle suspension shackles. These seals hold the grease to remain around the horizontal pins after a pressure gun has...

The placement of rear axle bumpers by GM on 1/2 tons proved to be an important feature. Owners can often load cargo over recommended weights, their shock absorbers may lose their resistance, and there is the existence of uneven road surfaces. All this can make axle bumpers very important. During the hauling of freight, these bumpers occasionally stop metal to...

  Leaf spring width on 1/2 ton pickups remained at 1 3/4 inches until the introduction of the two inch width on the Task Force 1/2 tons in mid 1955. The early narrow springs worked well considering the engine horsepower and weight limitations of the 1/2 tons. The two inch springs became standard equipment on the rear of the 3/4...

The straight axle ½ ton GM pickups (1959 and older) were built tough! They served their purpose as the best in work vehicles for over 30 years. Other than an occasional kingpin replacement, they were almost 'bullet proof'. In today's world, the reasons for owning an older truck, has generally changed. Most have been retired from work responsibilities and have...

Early Shock Absorbers Trucks of the Advanced Design years were often exposed to the rough terrain of local gravel roads as well as the dirt ruts on the farm. Quality, long life shock absorbers were a necessity. Therefore, this series of trucks in 1947-49 continued with a proven design of shocks carried over from the earlier vehicles. The highly successful...

Mechanical components on trucks were usually kept for many years by GM. Unless an improvement was needed, there was no need to change a proven design. An excellent example of this is the rear ½ ton axle bumper. The design was used from 1929 through 1946 on Chevrolet and GMC ½ tons. A rubber bumper is held down on the...
