A global leader in the manufacture and distribution of aftermarket cooling products for automotive, heavy truck, and industrial applications. Specialized in the production of OE-quality Radiators, Condensers, and Charge Air Coolers for US and international markets, covering over 10,000 part numbers worldwide.

Product Features:
  • We design and manufacture all our radiators to meet or even exceed Original Equipment specifications. We take pride in producing the most reliable replacement parts in the market.
  • Thermal expansion cuts allow for longer life and reduced failure rates by allowing improved core expansion and contraction during normal heat cycles.
  • Our B-Type tubes feature central reinforcement to provide greater tolerance to pressure. Stronger tube design means drastically reduced probability of tube failure.
  • We use longer header tabs for increased pressure resistance. This reduces the potential for tank to header leaks.
  • Our deep extrusion header provides a stronger tube to header joint which is more resistant to the effects of vibration and thermal tube expansion, virtually eliminating tube to header leaks.
  • Our fin edges are folded for increased stability and heat disbursement properties.
  • Our included “multi-fit” attachments allow one radiator to cover multiple vehicle applications without sacrificing OE fit. This results in wider vehicle coverage with substantially less inventory.
