Prior to disconnecting the connecting rods look at the end clearance using feeler gauges to make sure the the clearance is removed; if the end clearance is beyond the service limit then new connecting rods may be needed.

If there is such resistance, then check whether all the ridge material has been provided fully.

Chevrolet Astro Piston

Chevrolet Astro Piston is an important part since it causes the van's wheels to spin through the rotating motion caused by the explosive combustion force. Within the cylinder, the Piston seals via rings trapping pressure. A connecting rod links the Piston to the crankshaft so its straight line strokes become smooth rotation. Piston designs for factory Chevrolet Astro models utilize lightweight cast aluminum fabrication for strength and heat resistance for daily duty yet still provide the usual Chevrolet punch. As time went on, there became the option of hypereutectic aluminum for mild power tweaks, plus forged or billet versions for high output builds. These offer Astro owners more durability, using denser metal with advanced coatings on the skirt and crown to fight scuffing and reflect heat with each upgraded Piston. Considerations such as bore size, compression ratio, wrist pin fit, and valve clearance guide you in the right direction for proper selection regardless of style. Since the slim steel or ductile iron ring packs with plasma moly or chrome faces cut friction while helping seal harder, every Chevrolet Astro responds crisp, runs efficient, and is ready for more miles.

Each OEM Chevrolet Astro Piston we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
