5843-301-114 ZF PISTON ROD

This little guy connects the piston to the connecting rod, and ultimately to the crankshaft. Basically, it takes the up and down motion of the piston – from the combustion in the cylinder – and turns it into the rotational force that actually drives your wheels. It’s a pretty simple part, but it has to be incredibly strong. It’s constantly under a lot of stress, pushing and pulling. Think of it as a key link in the chain that transfers power from your engine to the transmission. Without it, that energy just…goes nowhere. It’s part of what makes your engine actually go. You won’t directly see it working, naturally, since it’s inside the engine, but it’s essential for every trip you take. This part needs to be tough because it’s under some serious pressure with every explosion happening in your engine. If it bends or breaks, you’re looking at major engine damage, potentially a complete failure. You’ll notice if something’s wrong pretty quickly; it’ll usually be a knocking sound coming from the engine, loss of power, or just the engine not running smoothly at all. It’s something you really don’t want to mess around with. A lot of folks order these from places like Fixparts Online to ensure they're getting a quality replacement. It's a relatively inexpensive part when you consider the cost of a ruined engine. It’s really that important. It acts like a shield, protecting the rest of the engine from a lot of force.
