Product Features:
- Our B-type tubes feature central reinforcement to provide greater tolerance to pressure. Stronger tube design means drastically reduced probability of tube failure.
- 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.
- Thermal expansion cuts allow for longer life and reduce failure rates by allowing improved core expansion and contraction during normal heat cycles.
- 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.
- We use longer header tabs for increased pressure resistance. This reduces the potential for tank to header leaks.
