SEMA 2018: Proform Slim-Fit Radiator Systems Might Change Your Life

LAS VEGAS, NV — Proform Parts just changed the world for performance radiators.

Car builders, hotrodders, and engine swappers have been cobbling together radiators and fans for their engine-cooling systems—and squeezing them (or trying to) into unforgiving places—for the better part of a century.

Welcome to the future.

Proform introduced its brand-new entry into the radiator market at the 2018 SEMA Show on Tuesday—the Proform Slim-Fit Radiator System—which will be making waves throughout 2019 and beyond.

As radiators and electric fans go, this thing looks rad—and we say ‘thing’ because Proform’s radiator-engineering magicians have spent the past three years creating an all-in-one direct-fit (right out of the box) unit which includes your all-aluminum radiator, shroud, electric fan, adjustable thermostat, wiring harness, and radiator cap all fully integrated together and pre-assembled.

“Basically, you just plug it in,” said Booth Platt, Proform’s project manager, in a SEMA Show interview.

Less time cutting, welding, drilling, and mounting. More time hugging yourself and driving fast.

All of that would be super-cool on its own, but the real magic of this SEMA product launch lies in how thin Proform has made these all-in-one radiator systems. What typically consumes upwards of eight front-to-back inches of under-hood engine compartment space, Proform has cut nearly in half.

Proform is officially using the 4½-inch number, but a little birdy told us the Slim-Fit Radiator Systems are going to get even thinner.

Conservatively, the new Proform Slim-Fit is 40-percent thinner than your typical radiator/fan/shroud combo.

The company’s product engineers accomplished this by flipping the fan and fan motor around, so that the fan motor is actually mounted inside of the radiator because the Proform team is apparently awesome at brazing. The design doesn’t compromise the radiator’s cooling capabilities, Proform officials say.

“The fan motor inside of the radiator core is the heart of the innovation,” Platt said.

The design involving and surrounding the motor is covered by a couple of patents, and a patent is pending for the overall design of the shroud and core, Platt said.

These Slim-Fit radiator systems will be available to buy in January 2019.

There are currently 14 Slim-Fit radiator system part numbers for a wide range of both automatic- and manual-transmission Ford, General Motors, and Chrysler classic muscle car applications—from 1959 Chevy Bel Air to Fox-body Mustangs—as well as 1995-2002 Chevy S-10s and their GMC counterparts.

Each contains either a 14- or 16-inch high performance fan blade, Platt said.

Watch and listen to Platt tell our friends at Summit Racing about these new Slim-Fit radiator systems.

 

Any Chevy S-10 owners in the house? Swap in a small block Chevy or LS engine, and what do you have left for the radiator space? Five inches—that’s what. Five inflexible inches.

This 4½-inch Proform Slim-Fit radiator system is your new best friend.

A subsidiary of Warren, MI-based aftermarket performance company Specialty Auto Parts USA Inc., Proform is known for a range of products, including valve covers, differential covers and rear axles, distributors and ignition accessories, carburetors, gear drives, harmonic balancers, fasteners, gaskets, and much more.

You can now add skinny radiator and fan combos to that list.

    I definitely interested. Building a custom 62 Falcon with 302 stroker Offenhuser tunnel ram 2 Holleys on top.
    Around January I’m looking for cool in the Falcon to keep it’s cool.

  2. Got a 1963 oldsmobile cutlass thats getting a 350 sbc in it and this would help with space .

  3. Would love too put this in my 84ss Monte Carlo it would be slick.!!

  4. Do they plan on making any for older Fords? My Dad has a 48 Ford coupe and it is impossible to find aluminum radiators for it.

    • Maybe one of our Universal Ford models will fit since they start at smaller widths than the direct-fit versions. Cores start at 17″ wide and go up from there.

  5. DWAIN HUMPHREY says:

    ARE THEY GOING TO MAKE ONE FOR A 66 CHEVROLET C10 TRUCK

  6. hope the build one for the c-4 corvettes, over heating is very common in these and on the forums is a teady question on how to reduce temps. come on guys, put one in my 86 vette,

  7. I WOULD DEFINITELY CONSIDER IT IF & WHEN MY 93 VETTE ORIGINAL RADIATOR NEEDED REPLACEMENT.

  8. how will road miles, bumps, vibrations stand up to usage being the fan is bolted to the radiator core?

    i dont see any other supports besides the welded section

    • Good question. The core mounted tank will be supported from above and below by larger extruded tubes that offer a significant strength increase versus standard rolled tubes. In addition to strength, they will also flow.

  9. Robert Bracco says:

    Will this work for road racing applications? I am building a 1989 Camaro for vintage road racing.

  10. How about a 35 dodge got one for that
