Product Description
This damper fits all 351, 361, 383, 400, 413, 426 and 440 engines, including Street and Race 426 Hemi models.
Does not fit early 331/354/392 Hemi.
This damper is supplied as a neutral balance damper with two counterweights with the damper.
1972-'78 383 & 400, '71 383 2-bbl and '74-'78 440 (cast iron crank engines only) use counterweight #91015, which is the larger, heavier bolt-in weight.
1970-'71 440 6-bbl and all others with 6 pack connecting rods (1971 High Performance 440) use counterweight #91016, which is the smaller, lighter bolt-in weight.
All other Chrysler big block engines are neutrally balanced and therefore no weight should be installed!
The shock also has two additional TDC markings for the 426 Hemi for street or track use.
A spacer is also required for the Hemi.
This shock will not fit the 331, 354 or 392 early Hemi, but will basically fit all other big block Chrysler engines, including the
351, 361, 383, 400, 413, 426 and 440
