The Hot Ones – A Guide to Tri-Five Chevy Parts

It can be difficult to pinpoint one specific reason for the popularity of Tri-Five Chevrolet’s 1955, ’56, and ’57 models. The ’55 was an all-new design that seemed sportier and more youthful compared to the pedestrian models prior. Also, the introduction of the 265c.i. small-block V-8 certainly perked up the performance of the new model.

Or is it simply that so many were produced (just short of five million units) that it was easy for hot rodders to get their hands on one to build and race? It’s probably a combination of all those elements, but no matter your opinion you cannot deny the love of the Tri-five Chevy in the hot rodding world.

Today, you can pretty much build an entire ’55-’57 Chevy without using an original Chevrolet component. From complete bodies and chassis, to interior trim and moldings, there are enough parts to build and personalize a Tri-five to be exactly like you envision. We learned that companies are still designing new parts to help Tri-five fans build the car or their dreams, whether it’s restored or modified in any style. Take a look!



Classic Instruments

A New Era

Craving for modern instrumentation but still want a factory appearance for your ’55 or ’56 Chevy? The Bel Era III direct-fit gauge package from Classic Instruments is right up your alley! The assembly features an easy-to-program electronic speedometer, fuel gauge, oil pressure, temperature, and volt gauge all in a stock-appearing unit. The cluster features bright LED lighting with a built-in dimmer, turn signals, high-beam indicator, and an additional warning indicator. Best of all, the Bel Era III works with any fuel pump sending unit and accepts signals from ECM speed sensors so no other controllers are required. Available in three colors, the packages also have optional gear indicators and a matching clock available.

Real Deal Steel

Tunnel Expansion

You can’t beat the benefits of lower cruising rpm thanks to an overdrive transmission. In most cases, these modern transmissions such as a Tremec T56, 4L80E, or the newer six-speed automatics will require modifications to the tunnel. Real Deal Steel now offers a larger trans tunnel to help clear the extra girth of a modern OD trans. The new tunnels, formed of 16-gauge steel, are two inches larger and will work with stock or recessed firewalls. The enlarged tunnels are also available on any new Real Deal Steel body.

Tri-Five, tri-five chevyAmerican Autowire

Restore or Restomod

Some like their Tri-fives stock, while others prefer to see things modified. Regardless of where you stand (or drive), American Autowire has you covered. For the restoration lovers, their Factory Fit product line provides harnesses that are handmade from the original GM blueprints and tooling! For gearheads looking to power EFI, electric fans, fuel pumps or power windows, their Classic Update Series fits the bill. These systems are based on a modern ATO fuse panel and will replace every bit of wiring on your Chevy, including the correct taillight assemblies and sockets, switches, steering column connections and more!

Tri-Five, tri-five chevyBorgeson

To Everything, Turn…

With more than 60 years on their clocks, there are many parts that need replacing on Tri-fives to make them safe, reliable cruisers. One of the most important systems to consider for a rebuild or update is the old Saginaw steering box. Thanks to Borgeson and their Steering Box Rebuild Kits, you can retain the factory housing but update it with new internal components to bring it back to a tight, like-new feel. Kits are available in both 16:1 and 24:1 ratios with your choice of the original long input shaft or a shortened input shaft for use with aftermarket steering columns.

Their system comes with a highly efficient cross-flow aluminum radiator, dual electric fans, shroud and relays, a transmission cooler, overflow reservoir, and even a new A/C condenser!

Tri-Five, tri-five chevyDakota Digital

Stock but Not!

Dakota Digital’s new RTX series of instrumentation focuses on retaining a stock appearance and design elements but once you hit the power switch, the LED backlights glow to life and hidden features come to life! The original-styled three gauges are in place, but a tach, oil pressure, and voltage readout are supplied through hidden LED bars! A high-definition message center can be configured to your liking, as well as the backlighting colors. The RTX series is also available for ’55 and ’56 models.

Tri-Five, tri-five chevyFatman Fabrication

Fatman Frames

Wouldn’t it be cool to have a big, tall Tri-five that could keep pace with a modern muscle car? Fatman Fabrication offers a full frame to slide under your Chevy that’ll make it handle and ride like new. The 3×4-inch, 0.188-inch thick rails are complemented with a fully closed X-member creating a rigid foundation. Their proven IFS design is used up front while a 9-inch rearend is supported out back with a Prolink four-bar system. RideTech coil-overs are used on each corner along with a pair of heavy-duty sway bars. Engine mounts are available for any Chevy engine and a removable trans mount makes installation easy.

Tri-Five, tri-five chevyClassic Industries

Wing Windows

One of the simple pleasures of riding in a Tri-five is reaching for the vent window crank to crack open the little wing window to feel the breeze. Unfortunately, in many cases the glass is cracked or the frame is tweaked and the window is non-op. Classic Industries recently developed a new reproduction vent window assembly for all models, including wagons and Nomads. Each assembly includes a new vent frame with clear, green tint or gray custom tinted glass installed. Now you have no excuse not to get those fun little windows working.

Tri-Five, tri-five chevyCold Case Radiators

Keeping Cool

When Tri-fives rolled off the assembly line, the radiator could be in two positions depending on the engine. For six-cylinder engines, the radiator was positioned in front of the core support and for the new small-block V8, the radiator was placed behind the core support. Cold Case Radiators offers both designs in an aluminum assembly that was designed to look like a factory unit (once painted, it’s tough to tell!). Each radiator is 100-percent TIG welded and pressure tested. Sixteen corrugated fins per inch provide increased surface area creating more thermal transfer resulting in cool performance.

Direct Sheetmetal

Flowing Firewall

In many Tri-five builds, there’s a good chance the firewall is going to need to be replaced due to rust, shoddy repairs, or for a cleaner appearance. Direct Sheetmetal understands the need for a new firewall and developed a great-looking Custom Curved Firewall specifically for the three-year Chevy run. The assembly is crafted from 16-gauge cold-rolled steel with a custom curved top for a unique appearance. They also built-in a 4-inch setback for extra engine and distributor clearance. Direct Sheetmetal is a one-stop shop for floorboards and transmission covers to help complete your build.

Tri-Five, tri-five chevyNo Limit Engineering

Limitless Handling

With their history of making old trucks handle like sports cars, it’s no surprise that No Limit Engineering has developed a chassis to make a shoebox handle like it’s on rails. Their Pro 5 Chassis starts with stronger rails and an X-member designed to reduce chassis flex, producing a smooth ride with confident handling. The standard chassis includes a torque arm rear suspension and Wide Ride front system. RideTech coil-overs are incorporated along with a new Moser rearend housing and 31-spline axles. If you prefer the nose-high stance of a gasser, No Limit also offers a complete gasser chassis or front stub assembly.

Tri-Five, tri-five chevyVintage Air

Sure Fit Cooling

Vintage Air pioneered the concept of bolt-in full-function heat/cool/defrost systems for Tri-five Chevys and their latest Gen IV SureFit Systems are designed specifically for each model year. The systems are fully electronic (no more cables), which is achieved through a trick conversion kit that retains the OEM control panel. Additional features include infinite blower speed adjustment, high-volume defrost, and “just right” temperature adjustments delivered through separate heat and cool coils with a blend-air door.

Tri-Five, tri-five chevySteele Rubber

Long Roof Seals

Wagons have proven themselves as big, fun family cruisers. Tri-five wagons have plenty of glass to give everyone in the car a scenic view, but those big windows leave the opportunity for leaks and road noise. Steele Rubber now offers rear side window weatherstrips specifically made to seal the long glass of a 150, 210 or two-door wagon. The seals are molded from EPDM rubber for durability and were designed from the factory originals with properly molded corners for a precise fit. Each set includes the left and right seals for the rear side windows.

Tri-Five, tri-five chevyididit

Shift Style

There’s a number of advantages to going with a new steering column coupled with a shifter from ididit.

Ididit offers its columns for three- or four-speed automatics and the columns are designed to work with the original dash indicator (new pattern indicators are sold separately).

Tri-Five, tri-five chevyArt Morrison Enterprises

Framed for Performance

Hot rodders expect their old Chevys to handle horsepower they were never intended to have, corner with wide, sticky tires, and to stop like a new car. If you have these kinds of expectations for your Tri-five, you better start with a GT Sport Chassis from Art Morrison Enterprises and fit with their Multilink IRS system. Not to be confused with early-style Jaguar, Corvette, or other aftermarket double-A-arm designs, AME’s Multilink IRS is more akin to what’s found on supercars from Ferrari, Lamborghini, and BMW, which improves tracking under varying road conditions, offers more adjustability, and a provides a significant reduction in unsprung weight.

Tri-Five, tri-five chevyAutoRad

Built-in Intercooler

When you’re looking for a new radiator, you may save time, money and any extra hassles by going to one source for all your cooling needs. AutoRad offers a Tri-five system that comes with their efficient aluminum radiator, a new core support, two 14-inch fans, an overflow bottle, an A/C condenser, and in this example, an air-to-air intercooler with external trans cooler. (If there’s anything else you need, we can’t think of it!) Each hand-crafted AutoRad unit is furnace brazed, making the entire core become one. This process provides a much more reliable and consistent seal than a standard soldered joint.

Tri-Five, tri-five chevySeatbelts Plus

Three Points

Seat belts weren’t even offered as factory options in Tri-fives, though they were sold as a dealer accessory. Today, we wouldn’t dream of taking a drive to the grocery store without a seat belt! SeatBeltsPlus offers a three-point conversion belt kit specifically designed for Tri-five Chevys (bench or bucket seats). The belts feature a vintage-style chrome lift latch and come in a variety of colors to match any factory interior color option.

Danchuk

’56 Jewelry
