Product Features

Each piston is produced from high-grade aluminum alloy with an anodized or coated skirt to reduce friction and support dependable sealing. Ring sets use ductile iron and chrome-plated options to match original performance, and the pin bore is finished to a tight tolerance for a smooth, quiet fit.

Quality You Can Rely On

Every batch is dimensionally verified with precision gauges and CMM equipment before packing, and key components are 100 percent tested. Parts are cleaned, protected and packed in export-grade cartons to arrive free of rust and damage.

OE Cross-Reference Support

To speed up your sourcing, we provide accurate OE cross-reference numbers for every item. If you are unsure which size or reference fits your rebuild, our technical team will confirm the correct part from your engine code and vehicle data at no extra cost.
