Sealed Power Engine Piston Set P/N:1003NP 30 (Pack of 8)
Sealed Power 1003NP piston set for the 1953 Ford F-250 V8 3.9L and other vehicles replaces worn pistons in classic engine rebuilds. The cast aluminum piston set meets or exceeds OEM specifications.
Oil burning, low compression or a knock from the engine can mean worn pistons, but worn piston rings or scored cylinder walls can be behind them too, so sort out the cause before you replace anything. The 1953 Ford F-250 V8 3.9L takes eight pistons.
The vehicles it fits include the 1953 Ford F-250 V8 3.9L, the 1953 Ford Club V8 3.9L and the 1950-1953 Ford Country Sedan V8 3.9L, along with other Ford and Mercury models.
