In 1953 the R-170 series replaced the L-170 series. The R-170 series was made up of six models. The 16000 lb GVW R-170, 17500 lb R-171, and 19000 lb R-172 Standard models were the same mechanically but rated differently for different operating conditions. The R-173 Schoolmaster was a long-wheelbase school bus chassis. The R-174 Loadstar was a short-wheelbase, reinforced frame, heavy-duty 19500 lb GVW model suitable for dump trucks and the like. All of these models continued to use the 101-hp Super Blue Diamond BD-269 engine from the L-170 series with a standard 4-speed syncromesh transmission ( a 5-speed transmission and 2-speed axle were optional). The R-175 Roadliner was a short-wheelbase tractor model with a 19000 lb GVW and 35000 lb GCW. The BD-269 engine, 4-speed transmission, and 7.50-20 tires were “standard” items included in the list price but minimum required options were the 130-hp Super Black Diamond BD-282 engine, 5-speed transmission, and 8.25-20 tires. The Black Diamond was a new engine design, very similar to the Silver Diamond but bigger, with stronger components. In 1955 the power ratings were increased to 104 for the BD-269 and 137 for the BD-282.
