At the heart of your new SUV is Chevy's dependable and powerful Vortec V8. New for 2007 and 2008 is Active Fuel Management to help save some money at the pump. These small blocks are capable of getting most jobs done but when the load gets heavy the factory cast manifolds get in the way of performance and efficiency. JBA's Cat4ward® Headers designed for the Vortec V8 open up the breathing on your truck with high-flowing mandrel-bent 1-5/8" primary tube that merge into JBA's patented Firecone® merged collector. By reducing back pressure and turbulence in the exhaust, the JBA headers free up torque, horsepower and efficiency lost in the factory set-up. Get as much as 14+ hp and 21 lb-ft of torque at the tires. These headers also feature ultra thick 3/8" laser-cut flanges and are available in a variety of finishes to fit your specific needs. Each kit includes high quality hardware and thorough instructions for a professional bolt-on installation.

:: JBA PowerCables™ Ignition Wires ::

8mm JBA PowerCables™ p/n 0807.

When upgrading the performance of your SUV, you will want to upgrade your ignition wires to a set of JBA PowerCables™. Each set is custom tailored to your specific application so you get a perfect fit every time. JBA's performance ignition wires feature ultra-low resistance wire-wound mag conductors that allow more spark energy to reach the spark plug without electronic interference. JBA Powercables™ come with 100% silicone jackets for great resistance to high heat as well as abrasion and tears. The high heat boots give plenty of clearance for routing around the headers. Sport Truck magazine tested these wires and found they were less than 1/2 the resistance of the factory wires. The editors at Car Craft made an extra 5 hp on a project engine with a set of 9mm JBA PowerCables™. Installing a set of these wires is easy to do on the Vortec engines and they look great under the hood.

Most SUV owners probably know what it's like when the hill is steep and your V8 is running wide open to keep up with traffic. JBA's exhaust systems give the new 5.3L small block engine under your hood a less restrictive path to expel spent gasses freeing up extra ponies. This is one of the easiest ways to increase horsepower and torque on your truck. JBA's new exhaust system for the 2007 Tahoe and Yukon is engineered and tuned to deliver maximum performance gains throughout the RPM range without annoying interior resonance. These JBA kits feature 3" mandrel-bent stainless steel tubing, a fully welded stainless steel high flow JBA muffler, factory style exhaust hangers, and a great looking 3-1/2" polished and chrome plated stainless steel rolled tip. Power. Sound. Quality. JBA has it all.
