Universal Silicone/Aluminum Radiator Hose Kit, Complete Starter Kit

The Speedway Universal Silicone and Aluminum Radiator Hose Kit provides a modular cooling plumbing package for custom automotive builds. Designed as a universal starter set, it gives builders the fundamental bends and joins needed to route coolant lines when factory direct-fit hoses are not an option.

The included black hoses are constructed from silicone rubber, which offers high heat resistance and longevity under the hood. To handle various angles, the kit supplies 12-inch-long 90-degree hoses in both 1-1/2-inch and 1-3/4-inch inner diameters, an 8-1/2-inch-long 45-degree hose with a 1-1/2-inch inner diameter, and a 6-inch-long straight section measuring 1-3/4 inches.

Rigid connections are handled by two aluminum tubes that resist the corrosion commonly found on traditional steel options. These include a 12-inch 45-degree tube with a 1-3/4-inch inner diameter and a 6-inch straight tube with a 1-1/2-inch inner diameter. Both metal sections feature beaded edges that help keep connected hoses firmly in place during assembly and operation.

Keep in mind that this is a universal starter setup limited to 1-1/2-inch and 1-3/4-inch sizing, so applications requiring other hose diameters will need extra hardware. The product data also does not specify whether hose clamps are included in the package, meaning you may need to source your own fasteners.

Verdict: This Speedway kit is a practical choice for hobbyists and mechanics building custom radiator plumbing with 1-1/2-inch or 1-3/4-inch ports. It provides heat-tolerant silicone hoses and corrosion-free beaded aluminum tubes to simplify custom engine bay routing.

• Hose Material: Black silicone rubber
• Tube Material: Aluminum with beaded edges
• 90-Degree Hoses: 1-1/2-inch ID (12-inch length), 1-3/4-inch ID (12-inch length)
• 45-Degree Hose: 1-1/2-inch ID (8-1/2-inch length)
• Straight Hose: 1-3/4-inch ID (6-inch length)
• Aluminum Tubes: 1-3/4-inch ID 45-degree (12-inch length), 1-1/2-inch ID straight (6-inch length)
• Fit Type: Universal

A great fit if you:

• Are plumbing a custom radiator setup that requires tailored hose angles and lengths.
• Need 1-1/2-inch or 1-3/4-inch diameter silicone cooling lines for heat resistance.
• Prefer corrosion-resistant aluminum joins with beaded ends over steel tubing.

Consider something else if you:

• Require a direct-fit, pre-molded factory replacement radiator hose for a stock vehicle.
• Need radiator plumbing in inner diameters other than 1-1/2 inches or 1-3/4 inches.

What hose sizes come in this kit?
The kit contains 12-inch 90-degree hoses in 1-1/2-inch and 1-3/4-inch inner diameters, an 8-1/2-inch 45-degree hose in 1-1/2-inch inner diameter, and a 6-inch straight hose in 1-3/4-inch inner diameter.

What are the dimensions of the aluminum tubes?
You get one 1-3/4-inch inner diameter 45-degree aluminum tube that is 12 inches long, and one 1-1/2-inch inner diameter straight aluminum tube that is 6 inches long.

Why do the aluminum tubes have beaded edges?
The beaded edges are designed to help retain the flexible hoses securely once they are slipped over the metal tubes.
