Description

Worn piston rings are one of the most common causes of compression loss and excess oil consumption in high-mileage engines. If your engine is showing signs of blow-by, white smoke, or declining power output, a fresh ring set restores proper sealing between the piston and cylinder wall—critical for maintaining peak compression and fuel efficiency. The PARTS UNLIMITED Ring Set R9040-1 delivers OEM-equivalent performance at a fraction of the cost of a full engine rebuild.

This is a direct replacement ring set designed for single piston applications, making it ideal for staged rebuilds or targeted repairs when you're not ready to overhaul the entire engine.

  • Fits: Single piston
  • MPN: R9040-1
  • OEM replacement quality
  • Restores compression seal
  • Reduces blow-by
  • Bolt-on installation

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
