Innovative high performance piston skirt design that provides:

1. Smaller piston to bore clearance

2. Less noise

3. Better ring seal

4. Higher power

5. Durability

Features:

Anti detonation grooves: protect the top ring by disrupting detonation waves and reduce piston-cylinder contact in high temperatures and engine RPM conditions.

Accumulator groove: accumulates residual combustion gasses reducing top ring flutter and improving seal.

Pin oil lubrication by broaches and oiler to reduce friction and increase durability.

Piston rings 83,5mm set

Contains 01 complete set for 5 cylinder engine.
Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.
Ring thickness:
1st ring 1.5mm – Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm – Made of cast iron.
3rd ring 2.0mm – Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.

All SPA Turbo connecting rods come with CMD Extreme Pressure lubricants.

About CMD Extreme Pressure lubricants:
– When the operation requires extreme pressure, all ordinary lubricants break down and allow metal-to-metal contact with consequent scoring, frictional heat, work and cutting tool damage.
They will not corrode the finest surfaces nor will they mulsify with cooling liquids. But these facts are not the most remarkable feature of CMD lubricants. The truly outstanding property of CMD is its ability to withstand extreme pressures!
CMD EXTREME PRESSURE lubricants are regularly used from 40,000 to 50,000 psi.
