Product Information
Specification

We have been working with Diamond to offer a piston designed for our engines, with perfectly cut valve reliefs to allow for more radical cams without concern of piston to valve contact.  Stock pistons tend to see the exhaust valve "kiss" the pistons on aggressive lobes used in max effort setups. Due to a lack of options for piston rings and sizes, we only use 1.2/1.5/3.0 custom Total Seal rings. These are the advance profile, with the options for a Napier 2nd ring recommended for boosted applications and a gapless top ring.

Pistons are a 2618 Alloy, designed with the clearance in mind for the bore size specificed.  We recommend measuring the pistons before the block is bore/honed to be certain of final clearances.  Due to the stock rod using a custom size pin, we can only offer Tool Steel H13 pins, which is normally an upgrade on our other pistons that use the Chromoly 4130 pins standard.  If you need a size other than stock, please contact us.  Pistons are designed for press fit rods.

Compression is based on 3500 heads and stock .060" thick head gasket. 

Optional Upgrades

Coatings

  • Skirt coating to reduce friction.  This is common for even stock replacement pistons and highly recommended
  • Thermal coating to crown to reduce heat transfer and keep the energy in the combustion chamber. 
  • Double Diamond hard anodize with skirt coating.  Our choice for max effort builds. 

Pin Upgrade

  • H13 Tool Steel with increased wall thickness compared to our standard pin.  Highly recommended for max effort engines.

Machining

  • Double Pin Oilers (Banana Groove).  Similar principle as an oil squirter, but using the natural motion of the engine to throw oil under the piston
  • Maxi-Lite internal mill.  As it sounds, reduces weight from the piston where it isn't necessary for strength.  This is great for high RPM.

Piston Rings

  • Total Seal Advanced Profile Steel Ring Set
    • Manufactured from 440B stainless steel
    • Stronger, Longer life and Most Precise Tolerances
    • Saves money (fewer teardowns)
    • Thinner, Flatter and Lighter
    • Conforms Better to the Cylinder Wall
    • Works well in all applications, notably dirt environments
    • Easier on cylinders, reducing bore wear
    • Uses C33 face coating: doesn't allows dirt to penetrate coating
    • Available in Gapless or Conventional
  • Total Seal Gapless Top Ring option reduces blowby, increasing power slightly.
  • Total Seal Napier 2nd Ring option improves oil control, and is recommended for all applications. Highly recommended for forced induction applications.
