ArmorGlide® Skirt Coating:

Wiseco's proprietary ArmorGlide® skirt coating is a high-tech dry-film lubricant developed through in-house dyno testing. It reduces friction, allows tighter piston-to-bore fitment than uncoated pistons, and improves wear resistance. The tighter fit also reduces piston rock noise and enhances ring seal for improved power output.

Professional Series Features:

  • Gas porting improves ring seal and reduces blow-by under extreme cylinder pressures
  • Optimized valve pocket geometry maximizes flow around the valve, accommodating oversized valves and high-lift camshafts
  • Crown shape engineered for maximum intake charge scavenging efficiency during valve overlap events
  • Dome geometry promotes optimal quench during the compression/combustion cycle, resisting detonation and pre-ignition
  • Precision-machined ring grooves with calculated root diameters and axial widths for maximum ring seal and minimal blow-by and oil consumption
  • Complex skirt profiles reduce friction while maintaining bore stability for consistent ring seal
  • ISO-certified forging facility utilizing advanced materials, complex forged shapes, and feature-aligned grain flow technology
  • Engineered, forged, and machined in the USA

Rings are sold separately. The recommended ring set for this piston is W77008-4560-5. Wrist pin S462 is included.

Easy to use great price

You seem to have the best price and your pictures help a lot. HOWEVER -- no place did my order say "Mercury Grand Marquis 2003 *Passenger Side* Glass -- and that has me concerned because I have to go by make/model/yr and then picture alone!

Autoplicity ships fast and has quality products for great prices. I am very pleased with their degree of service. A+++

Easy to navigate and fast checkout. Product was perfect, all springs spec'd out on the money, thanks. A+++++++++++++++++++

Great company to deal with. I placed an order with them (albeit an incorrect shipping address) and before you know it I'm expecting delivery in a very short amount of time. I also did have to call and attempt to correct my address error when the customer service rep let me know that all is well and set to be delivered to the correct address. I appreciate the fact that the gentleman on the other end of the phone was reassuring, courteous, and professional. I'd certainly do business with them again as the prices and customer service can't be beat!

Thank you for having this in stock with free shipping

Easy to navigate Processing and shipping seemed to take awhile

Certainly the lowest price for the exact same product that other websites offer. I ordered on Monday and got half of my order delivered just two days later. You can't beat that service. It's also great to call and get a real live person on the phone in a matter of seconds. Will definitely order from them again.

Easy to order

Best price on the internet for my Cobra H&R springs, reasonable shipping, tracking number provided. Couldn't ask for more. Will definitely be back for more.

Parts arrived in a timely fashion. Packing could have been better but product arrived safely.

A breeze...

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
