1955 - 1957 Chevy V8 SBC Mount (engine side mount) - HD3 Dual 1-1/4" Tubes - High Horsepower

Imagine this: You're cruising in your Tri-5, the rumble of that big block echoing in your ears. You push the pedal down, unleashing the beast under the hood... and then it happens. The temperature gauge starts to climb. That sinking feeling hits you – overheating. Again.

Frustrating, isn't it?

You've tried those "heavy-duty" 3 and 4-row radiators, but they're just not cutting it. They're bulky, inefficient, and leave you stranded on the side of the road with steam billowing from under the hood.

It's time for a radiator that can handle the heat.

Introducing the ultimate cooling solution for your 1955 - 1956 Bel Air, Nomad, or any Tri-5. Great for applications up to 750 horsepower when you need all of the cooling you can get.

Note: This RAD-1427-HD3 mounts in the V8 small block position with the radiator mounted on the engine side of the core support. For original 6 cylinder cars or for the big block mounting position, use RAD-1425-HD3 for your Tri5.

This isn't your average radiator. Our HD3 series features a revolutionary 2-row design with massive 1-1/4" tubes – bigger than many "high-performance" options. It's engineered to deliver maximum cooling efficiency in a lightweight, compact package.

Here's why it's the last radiator you'll ever need:

• Unleash the full potential of your engine: Keep your Tri-5 running cool, capable of cooling up to 750 horsepower with mammoth dual 1-1/4" tubes. 

• Leave overheating in the dust: Our superior 2-row design outperforms bulky 3 and 4-row radiators.

• Lightweight and durable: All-aluminum construction for maximum performance and longevity.

• Show-stopping style: Polished die-formed tanks give your engine bay a classic look.

• Built to last: Fully TIG welded with a billet CNC machined filler neck. No cheap, flimsy parts!

• No cheap garbage transmission coolers: We use heavy duty plate transmission coolers, not the garbage concentric transmission coolers used in 3-row and 4-row rads. Most of them won't cool a Prius, let alone your hot rod.

Plus:

• Limited Lifetime Warranty: Drive with confidence knowing you're covered.

• Direct fit for 1955 - 1957 Bel Air and Tri-5s: Installation is a breeze. Note this will not fit Tri-5 cars with the curved upper hose connection offset towards the drivers side. For those cars and 1957 models, use part number RAD-1426 for your Tri-5.

Don't let another overheating issue ruin your day.

Experience the difference a truly high-performance radiator can make.
