Engine Parts...At Any Speed!
From domestic and import passenger car, light truck, heavy duty, industrial, marine, agricultural and performance applications - we've got the parts for your speed.

History | Tradition
Piston Engine Parts, known locally as Don Gross Warehouse, has been a family owned and operated company since 1972 with locations in Los Angeles and San Diego.

While we began as a regional factory warehouse for Ertel/Nylen,
Silent Timing, and US Tool we quickly grew and expanded to
meet the full range of product needs which our engine rebuilder
and Jobber customers required. Today we offer a complete selection
of hard parts and shop supplies to service the area – from brand
favorites to best values - fulfilling stock orders to WDs, PERs, and Jobbers as well as master kits built-to-order for the
engine rebuilders.

The Parts You Need...
When You Need Them!

We provide engine parts to rebuilders in Southern California, the Western United States, Baja Mexico and beyond, and we are dedicated to maintaining the highest standards of quality and knowledgeable, friendly, and professional customer service.

Engine Parts Inventory
We stock engine parts. We don’t get side-tracked stocking bug shields or running boards. With two locations, over # SKUs on hand, and a sophisticated computer system that projects demand and tracks lost sales, we have the parts or engine kit you need for domestic, import, heavy-duty, agricultural or industrial applications. And if you’re looking for hard to find parts, or we don’t have something you need on hand, we can get it. In addition to our 80+ regular engine parts suppliers, we have over 100 specialty engine parts suppliers, our Parts Finder network of 30 other Engine Pro distributors, and eight customer service agents dedicated full-time to helping you find you the parts you need, on-time and at a fair price.
