Radiator Supply House

What Radiator Supply House does

Radiator Supply House (RSH) is a privately held manufacturer of replacement and OEM cooling systems headquartered in Sweet Home, Oregon. Founded on March 3, 2003 by brothers Will and Ryan Garrett, the company designs, fabricates, and distributes metal replacement radiators, steel tanks, all-aluminum radiators (marketed under the Icebox Performance sub-brand), oil coolers, charge air coolers, and A/C condensers. Its core production technology is a full in-house fabrication facility operational since 2009, supported by 2D drafting and CNC plasma cutting, enabling both stocked and build-to-order units across more than 10,000 SKUs in inventory.

RSH serves five equipment verticals: trucking (semi-trucks such as Kenworth, Peterbilt, Freightliner), construction and heavy equipment (Case, John Deere, Komatsu, Caterpillar), agriculture, RV/motorhome, gen-set/power generation, and oil/frac. In 2022, the company deliberately shifted its focus from general vehicle cooling to OEM manufacturing and larger cooling systems for industrial customers in construction, logging, mining, agriculture, and trucking.

The business model is hardware sales through a hybrid distribution mix: a direct-to-consumer Shopify e-commerce site, an eBay storefront launched in 2010, a mobile app, and a nationwide dealer network with tiered dealer pricing activated within 48-72 hours. Pricing is quote-based with no public list; a 1-year limited warranty applies to most products and a lifetime warranty applies to semi-truck charge air coolers. Operations run from a 12-acre facility opened in 2017, employing nearly 60 people as of 2023. The company is entirely founder-owned with no disclosed institutional investment.
