Chevrolet's 4.8L, 5.3L and 6.0L Vortec V8 engines are the perfect platform for nitrous injection upgrades. ZEXT is at the forefront of nitrous technology by developing an innovative wet nitrous system specifically for these popular trucks. The ZEXT Silverado Edition Nitrous System comes factory pre-assembled, making for a simple and easy, 2 hour, plug and play installation. Every hose, wire and fitting has been engineered and manufactured for a truly custom fit on your truck; you simply won't find a better looking, more powerful or easy-to-install nitrous system on the market today.

In addition to perfect fit and ease of installation, the new ZEXT Silverado Edition Nitrous System incorporates the most technically advanced performance features available, including the patented ZEXT Active Fuel ControlT. This innovative performance and safety feature automatically adjusts the nitrous fuel enrichment so your engine never runs too rich or too lean. ZEXT engineers always keep ease of use in mind when designing their systems; the ZEXT-patented electronic TPS switch is a case in point. This switch uses the engine's throttle position sensor to electronically activate the nitrous at wide open throttle, leaving you to concentrate on driving, not fumbling with a push-button. Power settings are fully adjustable from 75 to 125 horsepower with the included tuning jets.

Installation of this kit is quite simple includes all of the special parts needed and should take no more than 2 hours to complete.

Traction Control Window Switch

Looking for a safe and easy to select the precise rpm for your nitrous system activation?
The new ZEX™ Traction Control Window Switch is a completely self-programmable and fully electronic component that allows you to easily select the rpm range of nitrous system activation, both lower and upper rpm limits.

Incorporating ZEX™ Skip-Shift technology, the ZEX™ Traction Control Window Switch allows you to block out first gear nitrous activation where excessive power could cause lost traction, especially with street-tire class racecars. With Skip-Shift, the nitrous injection is held off until the shift is made into second gear (and subsequent gears) where the nitrous power can be fully utilized

ZEX™ Nitrous Pressure Regulator

Looking to eliminating bottle pressure drop?!
The key to making maximum power is keeping nitrous bottle pressure between 900 psi and 1000 psi. Unfortunately, as soon as you start injecting nitrous, bottle pressure begins to drop and horsepower is lost. At the end of a typical quarter mile run, your nitrous system horsepower can be down as much as 20 percent!

The ZEX™ Nitrous Pressure Regulator features an advanced regulator with flow capacity in excess of 500 hp, making it ideal for any performance vehicle or racecar. This easy to install system is fully adjustable from 500 to 1100 psi. The ZEX™ Nitrous Pressure Regulator Kit features everything you need for a complete installation, including AN fittings, a pressure gauge and a complete installation and tuning guide.

Triple Fire™ Spark Plugs
V8 Performance Spark Plugs

RPM Outlet’s never ending quest for performance has led us to a proven ignition upgrade that will increase performance and provide unheard of increased horsepower, durability and longevity at the same time. Our research has lead us to a company that has been developing new technology for over 20 years. Zex is the one of the largest manufactures of Nitrous Oxide systems and accessories. We found that they have been manufacturing complete line performance spark plugs for over 3 years. ZEX™ Igniter Core™ Technology uses a center electrode of pure copper, surrounded by a high purity nickel shell for durability. This special construction conducts electricity and heat over 5 times better than platinum and almost 3 times better than iridium. The result is more horsepower producing spark energy and greater detonation resistance than platinum or iridium can deliver. Another groundbreaking development is Clean Fire™ Technology. It uses the spark from all three ground straps to aid in super-cleaning the center electrode. This burns off excess carbon and ensures you get maximum ignition power and superior resistance to fouling, even after hours of idling and stop and go traffic. When you look at all this new plug technology, its clear ZEX™ has a better choice for those serious about performance. Two different plugs have been developed with optimized heat ranges for the specific modifications and power levels you have. For engines with bolt-on performance parts and computer tuning, up to 400+hp, our Power Tune™ Plug is ideal. For those engines with nitrous, blowers, or turbos, our Power Racer™ Plug will maximize performance in engines up to 700+hp. These are direct replacement high performance spark plugs. Installation is quite simple, includes all of the special parts needed and should take no more than 1 hours to complete.
