Quad and UTV piston rings - tightness, compression and engine power

( number of products: 253 )

Piston rings for ATV / UTV are small but extremely important elements of every engine. Their task is to ensure the tightness of the combustion chamber, maintain appropriate compression and control lubrication. At Bajamoto you will findpiston rings from the brandsVertex, ProX, Athena, Wossner andNamura – tailored to the most popular models of quads and UTVs.

Why is it worth replacing piston rings regularly?

Worn rings mean a loss of power, higher oil consumption and the risk of cylinder damage. During any engine overhaul, replacing the piston rings is an absolute must - it allows you to restore full compression and efficiency of the drive unit. New rings improve tightness, minimize friction and increase engine life.

  • maintaining factory compression and tightness,
  • lower oil and fuel consumption,
  • protection of the cylinder against scratches,
  • better engine performance and smoothness,
  • easy installation in sets with a piston or separately.

Types of piston rings for quads and UTVs

  • Compression rings – maintain pressure in the combustion chamber
  • Oil rings – regulate the amount of oil on the cylinder walls
  • Ring sets – sets matched to OEM and aftermarket pistons
