HKS STROKER KIT 1.75L LOW COMP STEP 3 G16E GR YARIS ( 21004-AT010 )
■Piston
Basic diameter: dia. 88 / Piston weight: 314g
- High temperature resistance A2618 material is used for thinner wall thickness and lighter weight.
- The billet processing reduces waste parts and achieves the lightest weight possible.
- The bridge-shaped structure increases the rigidity and allows weight reduction.
- Leads the cooling oil from the 3 oil jets to the proper location for effective cooling.
- Two-layer coating improves anti-seizing and reduces friction.
- Shortening the piston pin reduces the weight of the piston pin boss section.
- Dedicated pins with appropriate wall thickness are set to reduce weight.
- TOP RING improves the durability by titanium coating.
■Connecting Rod
- Uses machined nickel chrome alloy I-beam connecting rods.
- 25% stronger than the stock product.
- Compatible with a dia. 24 mm piston pin.
- The surface is finished with a WPC treatment to improve durability.
■Crankshaft
- Chrome steel-made full counter crankshaft.
- Inertia weight has been reduced by efficient counterweight placement and lighter pin parts.
- The balancer shaft was removed to improve response.
- 50% of the balance rate suppresses the vibrations unique to a three-cylinder engine.
