Low compression. Oil leaks. Too much exhaust smoke.
That usually means worn components—like cylinder heads, pistons, or head gaskets. Off-road machinery works hard, and these parts take a beating. Ignore them too long, and you risk total engine failure.
FridayParts carries direct-fit cylinder and engine parts to get your machine back in action.
If you're dealing with constant overheating or finding coolant in your oil, a warped or cracked head is usually the culprit. We supply direct-replacement cylinder heads (both bare and complete with valves) to get your engine compressing properly again.
Heavy workloads mean massive thermal stress on your pistons. If you notice a sudden drop in engine power or scuffing on the skirts during a teardown, it's time for a swap. Our aftermarket pistons are built to handle the intense pressure of tough off-road cycles.
Cylinder Block
As the core of your engine, a cracked or damaged block usually means a nightmare scenario of internal leaks and low oil pressure. Our replacement blocks ensure precise alignment for the crankshaft and liners, giving your rebuild a solid foundation.
Piston Ring
Blue smoke out of the exhaust or low compression? Worn rings are likely letting oil blow past into the combustion chamber. Swapping them out is the easiest way to stop your engine from burning oil and restore lost compression.
Cylinder Head Gasket
A blown head gasket usually shows up as white exhaust smoke, bubbles in your radiator, or that notorious milky-looking oil. Don't let it go until your coolant and oil mix completely and ruin the whole engine. Our replacements hold a tight fluid seal under high pressure to stop leaks before they start.
Overhaul Kits
Rebuilding an engine is enough work without having to hunt down individual pistons, rings, bearings, and gaskets from five different places. These kits pack everything you need for a complete teardown into a single box, with all components matched to fit perfectly together.
Cylinder Head Bolt & Kit
Head bolts stretch out once they're torqued down at the factory, so reusing the old ones during a head gasket job is a massive gamble. Grabbing a fresh set of high-tensile bolts is the only way to get the even clamping force you need to keep the head from lifting.
Cylinder Liner
Vertical scoring or a heavy ridge at the top of the bore means your cylinder walls are done. Keeping the engine running like this risks severe blow-by and oil consumption. Dropping in a new set of sleeves restores that smooth inner surface your new pistons need to seal and slide without friction.
Intake & Exhaust Valve
Burnt, bent, or pitted valves won't close all the way, dropping your compression and causing a rough, sputtering idle. Swapping them out for a fresh set gets the combustion chamber sealed tight again, so your machine actually performs when put under load.
Before you buy, check these three things:
Equipment type – Different engines use different cylinder parts. Know your engine model first.
Brand – We carry parts for Kubota, John Deere, Yanmar, Caterpillar, and others. Make sure we have your brand.
Material – Cylinder heads and pistons have to handle heat and pressure. Ours are built for it.
We test our parts hard. They hold up in the field.
