Russell Performance

<h3>Russell Performance: Race-Proven Fluid Transfer Systems</h3><p>Born on the drag strip and refined over decades of motorsport competition, Russell Performance has become one of the most trusted names in automotive fluid transfer. <strong>Founded by drag racer Dave Russell</strong>, the brand got its start when Russell began adapting surplus aircraft hoses and fittings for use on his race car — a practical, performance-first approach that still defines the company today. What began as a small speed shop operation grew into an industry-leading manufacturer with a dedicated engineering staff, an ISO 9001-certified facility, and a product catalog trusted by professionals and enthusiasts alike.</p><p> Russell Performance Products has built a reputation as a leader in advanced fluid transfer systems, manufacturing a complete line of hoses and fittings for fuel, brake, water, oil, and various other systems for automotive, motorcycle, and marine applications. Today, Russell is a proud member of the Edelbrock Group family of brands, representing over 130 years of collective performance expertise. </p><h3>What Russell Performance Makes</h3><p> Russell Performance manufactures high-performance automotive parts including hose, hose ends, adapter fittings, fuel management, brake and clutch hose, accessories, and supporting components for street, race, truck, Jeep, and off-road applications. The lineup spans an impressive range of product lines — hoses include the ProClassic, ProClassic II, ProFlex, ProRace, PowerFlex, and Twist-Lok; hose ends include Crimp-On, Full Flow, Full Flow Swivel, and Tube Seal styles; and adapter fittings cover AN, fuel-specific, Twist-Lok, and Universal Turbo configurations. </p><p>Among Russell&apos;s most popular offerings are their <a href="/602-russell-performance-stainless-steel-and-performance-brake-lines-and-hoses-12816">stainless steel performance brake lines and hoses</a>, which replace expandable rubber OEM hoses with braided stainless construction for more consistent, fade-resistant pedal feel. For brake system maintenance, Russell&apos;s innovative <strong>Speed Bleeder</strong> valves — which replace the original bleeder valve with a spring-loaded one-way ball and check valve design that opens to allow old fluid and air out, then closes automatically between pumps — have made brake bleeding dramatically simpler. These are found throughout Russell&apos;s <a href="/602-russell-performance-brake-vacuum-line-15400">brake vacuum line</a> product range.</p><p>On the fuel side, Russell&apos;s <a href="/602-russell-performance-fuel-line-11224">fuel line</a> assemblies and <a href="/602-russell-performance-fuel-hose-fitting-17252">fuel hose fittings</a> are engineered to handle everything from carbureted classics to modern EFI setups. Russell&apos;s wide variety of 6061-T6 aluminum fittings allow connection to almost any component, with adapters offered in standard, metric, and pipe thread to fit most popular pumps and filters — finished in Endura, traditional blue, or black anodized. Their <a href="/602-russell-performance-brake-hydraulic-hose-fitting-12217">brake hydraulic hose fittings</a> round out a comprehensive brake plumbing ecosystem that covers everything from street-legal daily drivers to dedicated competition vehicles.</p><h3>Trusted Across All Forms of Motorsport</h3><p> Russell has supplied innovative fluid transfer systems for everything from Sprint Cup to Top Fuel drag racing, off-road racing to high-performance street and marine applications, and most Russell hoses are NHRA approved for competition. The Russell team maintains a dedicated engineering staff and a state-of-the-art quality control department to ensure the best quality and consistency. Whether you&apos;re building a show car, a weekend racer, or a rock crawler, Russell&apos;s depth of product coverage means you can plumb an entire vehicle using a single, cohesive system.</p>

I ordered an exhaust setup (headers and a cat-back) late monday night, an it was shipped on wednesday. Thanks for a fast transaction Autoplicity!

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
