About
Located in Grand Junction, Colorado, ASF Machine caters to enthusiasts of performance & race vehicles. In our full service machine shop, we offer deck surfacing on Rottler equipment, block honing on Sunnen equipment, dynamic balancing, Serdi valve seat service and CNC milling for sleeve installation in select makes/models. We service domestic, European and Japanese engines.
As a compliment to our high quality, modern engine machining business, we offer R&R as well as repair services on select makes and models: mainly Subaru. We are your Western Slope source for independent Subaru repair. We specialize in the service of Subies: from your mom’s Outback to your prized WRX STi. We ❤️ Subarus, particularly those featuring Subaru engines like the popular EJ series (EJ20 and EJ25).
ASF Machine goes beyond typical repair services. Our expertise extends to crafting custom solutions with in-house capabilities like CAD design, TIG welding, and CNC machining. This allows us to design, fabricate, and precisely machine unique parts tailored to individual vehicles in addition to basic maintenance. We also offer a selection of specialty tools designed to address common maintenance tasks specifically on Subaru engines.
