Key Features & Benefits

This kit basically replaces the top part of your air compressor. Inside, it houses the piston, valves, and o – rings – all the stuff that actually compresses the air. It’s a complete assembly for that upper section, typically including a new cylinder, piston, head gasket, and any necessary seals. Some kits even throw in the piston rings and retainers. It's everything you need to rebuild that top end. Your air compressor, naturally, makes the compressed air that runs your air brakes, and a lot of other things on some vehicles – things like horns, suspension systems, or even powering certain accessories. The cylinder head is a critical part of making that air. It's where the actual compression happens. It takes the reciprocating motion of the piston and turns it into pressurized air. It’s responsible for building the air pressure needed to safely stop your vehicle.

Symptoms, Risks & Replacements

Honestly, this is a safety item. If the cylinder head is cracked, worn, or leaking, the compressor won’t build up pressure properly. You’ll notice if your brakes feel weak or slow to respond, or if your air gauges aren’t reading right. That's a big warning sign. Ignoring it could lead to brake failure. A good cylinder head kit restores the compressor’s ability to reliably create and maintain air pressure. It’s preventative maintenance that keeps you safe on the road. You can find a lot of these kits over at Fixparts Online, they usually have a pretty good selection for different makes and models. Replacing this before it completely fails is always the smart move.
