HRPartsNStuff Rear Swaybar
Product ID: 0450


 Our new swaybar / Anti-roll system transfers the force from one side to the other, doing a much more efficient job of equalizing the weight to each rear tire.  This in effect almost doubles the traction of a fast car with no air bags, because the passenger tire would have had very little weight on it.  With the added traction and the car being much closer to level, the car can now launch harder and straighter.  This reduces the chance of wandering out of the "groove" and further losing traction, while making it much safer to drive.  Not having to worry about the rear slicks getting cut or damaged from excessive body roll is an added bonus.

Aeromotive Billet Electric Fuel Pump Controller
Product ID: 16306


For any pump, on any type of vehicle, the Aeromotive Fuel Pump Speed Controller (FPSC) minimizes fuel heating and vapor-lock problems by matching the duty cycle of the fuel pump to engine RPM. At low demand, the FPSC slows the fuel pump down, reducing the chance of suction side cavitation and vapor lock. When demand increases, the FPSC returns the fuel pump to 100% duty cycle for maximum flow. It’s like an automatic transmission for your fuel pump.

Single Air Fuel Meter
Product ID: 170401


Proper engine tuning is essential to achieving maximum performance and avoiding costly, premature engine failure. Unfortunately, until now digital air/fuel meters have only offered single sensor measuring capability. This meant engine tuners were only able to monitor the air/fuel ratio on one side of the engine, while being left to play a guessing game with the other cylinder bank. Now there is a way to eliminate the unknown, allowing you to tune carburetor jetting and EFI air/fuel ratios with confidence and complete accuracy.

Dual Air\Fuel Meter
Product ID: 170402


FAST™ has revolutionized the tuning industry with the first two-sensor, wide-band air/fuel meter. The FAST™ Air/Fuel Meter uses a sensor in both of your engine's exhaust outlets (not just one sensor like competitive air/fuel meters) to get the full story on the state of your engine's tune. With the FAST™ Air/Fuel Meter, you can read both exhaust sensors individually or average them together for super accurate readings of the engine's true air/fuel ratio. For those on a budget, a single sensor version is available that can later be upgraded to the two-sensor technology.

Easy to use, the FAST™ Air/Fuel Meter includes a simple, built-in data-logger that doesn't require you to download to a laptop. It simply plays back your information on the unit's display screen in real-time. Advanced features include outputs for external data-loggers and digital gauges, as well as a narrow-band simulator function that allows you to feed your engine's computer a factory signal while using the wide-band sensor for air/fuel measurement. With double the sensors and double the performance, it's clear the FAST™ Air/Fuel Meter is the best choice for the serious engine tuner.
