CAPACITY UPGRADE KIT RB26DETT 2.8L STEP2 86.5 BCD

Based on the proven 2.8L STEP2 kit, this has been upgraded by combining it with a lightweight, high-rigidity forged BCD piston.

Features
(1) Piston kit

Thin wall thickness achieved by using A2618 material, which is resistant to high temperatures.
Structural rigidity increased by adopting a bridge structure.
Profile optimization shortens skirt height and reduces weight.
Shortening the piston pin reduces the weight of the boss.
Two-layer coating of fluororesin and molybdenum reduces friction.
(2) Crankshaft Stroke: 77.7mm

Uses specially forged material. In addition, full counter provides good rotation balance and allows for high rotation.
Lightweight pin journal and center are hollowed out to improve response.
(3) Connecting rod

Uses specially forged material. H-section to withstand powerful explosive loads.
WPC treatment is applied to the surface to improve fatigue strength.
