Used Piston & Cyl. Assy. 1990–2019

Blue smoke from the exhaust, poor compression, excessive oil consumption, or a knocking sound under load are all signs that pistons or cylinder bores need attention. A leak-down test tells you which cylinder is the problem before you start pulling the engine apart. A piston and cylinder assembly pairs the piston with a matched or honed bore, often including rings and sometimes the connecting rod. These matched sets restore compression and eliminate blow-by caused by worn cylinder walls. Redline carries 12 used piston and cylinder assemblies from 4 sellers. Many come from engines retired for other reasons -- a failed crankshaft or blown head gasket often leaves perfectly serviceable pistons and bores behind. Search by year, make, and model. Matching the bore size and piston diameter exactly is critical, so use the filters and confirm casting numbers with the seller before purchasing.
