Performance and appearance often go hand-in-hand when you're hot-rodding your car or truck. Some mods that improve performance and capability, like a high capacity aluminum radiator or high-flow intake manifold, look great naturally and provide a simultaneous appearance boost. But other parts like chrome valve covers may be installed more as eye candy than for any functional benefits. With our performance coolant hoses you can improve your vehicle's performance or appearance, or both.

When you build your engine to make more power, with high compression or forced induction, it will generate a lot more heat as well. The cooling system must be upgraded to handle the temperatures or your powerful, expensive engine will overheat. Mods like a high flow water pump improve coolant circulation, and high capacity radiators and cooling fans dissipate heat, but your coolant hoses should also be upgraded so they can reliably channel coolant throughout the system in a high temperature environment.

Most OE rubber hoses can't tolerate extreme temperatures, and they're also subject to deterioration from oil, fuel, and other contaminants. And even under ideal conditions rubber hoses must be periodically replaced. In contrast, our fiber reinforced silicone hoses are designed to withstand high temperature and pressure, and they're impervious to oil and fuel. In fact, they're so durable they'll probably last the life of your vehicle. But along with ruggedness and reliability you also get plenty of style because these hoses are available in a range of colors, so you can customize your engine bay. We offer complete direct fit silicone hose kits for most popular applications as well as universal hoses.

Their exceptional heat resistance and selection of colors makes our silicone coolant hoses a great choice when you want the ultimate in performance and style. And because our direct fit hoses are molded in the same shape as your OE hoses you can be assured of easy installation. But if you're looking for a different underhood effect consider our braided stainless steel reinforced flexible rubber hose. Available in a range of diameters and lengths, these hose kits include universal fit braided flex hose that can bend down to a 2.5” radius, so you can construct a unique custom cooling system. Kits come with chrome or anodized aluminum red/blue end caps/clamps that really set off the hoses, or without clamps.

But even if you're on a budget you can still have custom braided stainless steel hoses. Our braided steel sleeves can be easily slipped onto your coolant hoses, and give your machine a unique look at a fraction of the cost of AN stainless steel hose. They're cut to length for a perfect fit, and along with great looks will also protect your hoses from abrasion. Choose from sleeve-only kits or for the full custom hose effect, sleeve kits with anodized red or blue, or chrome, aluminum end caps/clamps. In addition to coolant hoses, sleeve only kits are also available for fuel and vacuum lines. Kits with end caps/clamps come with sleeves and end caps/clamps for radiator, heater, fuel, and vacuum hoses.
