S55 Billet connecting rod and Forged Piston set
- Mfg Part #
- ECS Part #
Billet Chromoly steel is the construction of these connecting rods, which gives them superior strength over stock parts. Usually referred to as "aircraft" or "aircraft-grade" steel, it boasts incredible tensile strength and superior uniformity. If you're increasing boost pressure this is a must-have upgrade. Forged aluminum was selected for the piston material due to its strength, popularity, and light-weight. Lateral gas ports ensure that the top ring seal is always as tight as possible and resist buildup more so than vertical ports do. Armor plating technology really makes these pistons shine. As with traditional coating technologies, heat causes the coating to wear off of the piston eventually to the point of no effectiveness. Armor Plating does not suffer the same effects.
** These Pistons are .002 overbore. Please note that cylinder walls will require a light hone to ensure proper fit. **
