Connecting rod bearings in a car’s engine help the rods better connect the pistons to the crankshaft, so it’s important that the bearings aren’t worn or there’ll be bigger, costlier ...

The ZZ4 pistons are hypereutectic cast-aluminum flattops with a short skirt, nearly identical to mid-'90s LT1 production slugs, as are the powdered metal connecting rods.

Having the stock connecting rods reconditioned would have cost about $80, and we'd have wanted to upgrade the rod bolts, which would've added another $40-$50. Instead, we opted for a set of used ...

Research connecting rods and you will find that there are two basic ways pistons are mounted to them. A bushed rod features a bronze bushing in the small end that the wristpin slides through, and ...

With both internal and external combustion engines, heat energy (expansion) exerts force on a piston and connecting rod tied to a crankshaft to make rotary motion.

According to Woodward, the benefit of that piston weight comes in the way of more torque down low. In the company’s own testing, a Thunder Rod-equipped 5.3-liter V-8 was reportedly able to match ...

A car engine is a piece of heavy machinery, and it isn’t surprising for it to make all kinds of sounds. The rotating shafts, the moving pistons and valves, the combustion process, and other engine ...

The crankshaft gets its power from the engine’s pistons. Each piston is connected to the crankshaft by way of a connecting rod and a connecting rod bearing.
