Dodge Plymouth Chrysler Mopar Speed Pro TRW Forged Pistons and Hypereutectic Piston Sets
TRW forged piston sets and Speed Pro forged pistons and hypereutectic pistons are available for many Dodge, Plymouth and Chrysler V8 engines. There are TRW pistons and Speedpro pistons available for the 318, 340, 360, 383 and 440 Mopar engines, including the 440 Six Pack. The majority of the piston sets are available in several different bore sizes and some models are available in different compression ratios.
All of the Speed Pro and TRW piston sets listed below come as a complete set of 8 pistons and they include the piston pins, and pin locks with the floating pin type pistons. Many of these pistons include low friction skirt coatings also. The piston sets are all weight matched before packaging. TRW forged pistons set the standard for years with their line of forged replacement pistons for stock type engines. Speed Pro forged pistons further that tradition with their line of Powerforged piston sets.
Speed Pro and TRW forged and hypereutectic pistons are great for use in high performance cars and trucks, street strip vehicles, race cars, hot rods, street rods or anywhere a stronger, better performing than stock piston is required.
Part numbers in the below charts with a H as the first digit are hypereutectic pistons, if the first digit is a L they are are forged pistons. Under Pin Type, P indicates the piston will work with a press pin type connecting rod, F means the piston will work with a floating pin connecting rod. If you see P or F it means the piston can be used with either type of connecting rod. FT under the top shape column means Flat Top piston, if it also has valve reliefs the number of reliefs will be listed also.
