Our promos are always pretty good here at Dallas Harley-Davidson in Garland TX, but this month might be one of the most exceptional of the year. Our Thanks for Performance Service Special changes every week of November to offer you money back on performance upgrade installation. If you’re planning your month, you might be wondering what you can expect at each stage. We’ll break down performance upgrades Stages 1-4, and we’re happy to talk more when you get in touch online, through chat or by phone.

One important thing to know is that when you schedule your performance upgrade through us, your original motorcycle warranty still applies. You get torque and horsepower improvements across the entire RPM range, without compromising your original or dealership warranty coverage.

Stage 1 Upgrade for Harley®

Spark plugs need oxygen to ignite fuel. With any combustion engine, more oxygen means more power when that oxygen is delivered efficiently. The focus of the Stage 1 Upgrade for Harley® is to get more oxygen through the system and therefore deliver more power to the back wheel.

Manufacturers have regulations that force them to use restricted air boxes and exhaust and to keep the amount of fuel entering the combustion chamber at set levels. They also have noise regulations. So from the factory, every Harley® is a fierce sounding, powerful machine, but it could be made even better.

A Stage 1 Upgrade allows bikes to move more air and more fuel. The kit includes an air filter that allows your bike to take in more air, a less restrictive exhaust and a tuner that increases the fuel that gets delivered. A Stage 1 upgrade increases performance by 10 percent and gives your Harley a deeper, throatier sound.

Stage 1 is a foundational upgrade, and components are compatible with all other upgrades. The first week of November, get $100 off installation of any stage-1 performance upgrade.

Harley-Davidson® Stage 2 Performance Upgrade

A lot of people get a Stage 1 performance upgrade, and they’re good to go. They’re happy with the enhanced performance and sound. But there are also those who are so delighted, they just have to know what happens if they continue to invest.

A Stage 2 performance upgrade is a cam change upgrade. In any engine, the cam drives the valves and the valves open to allow air in for combustion. The kits for improved lift, duration and timing focus on either torque or power upgrades.

The Stage 2 upgrade delivers up to 30% more horsepower and 10% more torque. November 8-13, get $200 back on installation of any stage 2 performance upgrade.

Stage 3 Performance Upgrade for Harley

Addicted to power? This month you can also get a Screamin’ Eagle Stage 3 Upgrade with our service special.

The Stage 3 kit includes larger diameter cylinders, high compression forged aluminum pistons and a performance cam upgrade that gives you an even higher lift than what you get from the Stage 2 upgrade kit. Clutch components, gaskets and other components help make sure your installation is seamless.

The Stage 3 kit improves torque by up to 24% over original equipment and gives you up to 39% more horsepower. It’s a bolt-on installation where the engine remains in the motorcycle while the upgrade is being performed and components integrated.

On November 15-20, receive $300 back on the installation of any Stage 3 performance upgrade.

Harley-Davidson Stage 4 Performance Upgrade

Take your bike all the way and give it the highest possible horsepower with a Stage 4 Performance Upgrade. The kit uses the pistons and cylinders installed during your Stage 3 upgrade, then adds a larger throttle body with a cast aluminum manifold to boost air delivery to the engine.

You get more horsepower because the air doesn’t just come in with greater volume, but also improved velocity. The upgrade also includes a cam with the highest available lift, a cam bearing, high capacity lifters, clutch components and all needed gaskets.

A Stage 4 kit delivers 24% torque improvement and up to 50% more horsepower than original equipment. Yep, you read that right. Up to 50% more horsepower targeted at higher RPMs.

On November 22-27, get a whopping $400 back on installation of any stage 4 performance upgrade.
