Fifth-Gen LSD

No, no. We're talking about Auburn Gear's performance-enhancing limited-slip differential, for Generation-5 V-8 Camaros. Unveiled last fall at SEMA 2013, the differential has a four-pinion gear design, and has been engineered to exceed the capability of the stock two-pinion OE (P/N 92230401) differential, thanks to an impressive bias ratio. Suitable for high horsepower rides, the new unit utilizes aircraft quality, 9310 heat-treated billet steel, known for its high-strength and endurance characteristics. The limited slip differential (P/N/ 5420138) from Auburn, supports 3.27, 3.45, and 3.73 gear ratios. Proudly American made, the replacement differential comes fully assembled, tested, certified, and ready for installation. No rebuilding is required.

Lose Weight

Get rid of some unnecessary weight, and improve your throttle response, while knocking seconds off of your ETs and lap times. Summit Racing has now begun to offer their aluminum driveshafts for 1967-2002 Camaros and Firebirds, and other popular models. The new setup uses seamless tubing that guarantees immense strength and rigidity. Thanks to the aluminum, the driveshaft from Summit Racing weighs much less than the comparable steel driveshaft, and come fully balanced and assembled from the factory, with high performance 1330-style U-joints that can withstand the additional horsepower produced by your beastly engine. Put your car on a speed diet, and pick up some extra time with a shaft from Summit!

Chill Out

Maximize your vehicle's performance, simply by ensuring that the air traveling into your intake is ice cold. Cold Air Inductions has been producing countless intake options, and the one pictured is their silver powder-coated version, with an aluminum tube, designed specifically for Chevrolet 6.2-liter LS series engines. The non-plastic intake tubes have a ceramic coat, on both inside and out to reducing heat soak, while keeping radiant heat from penetrating the ambient intake air. They have also applied 3/8-inch thermal insulation inside the air box to prevent heat transfer from the surrounding engine bay. Each one of the cold air intakes is TIG-welded by hand and powder-coated. As stated above, almost every engine is accounted for, so visit their website for specific product numbers!

Spoiler Alert!

Check out this new AgreSSive spoiler, for the 1993-2002 Camaro. Produced by 6LE Designs, the custom Camaro spoiler has the classic design of the 1998-and-up SS spoiler, and keeps the LED light. Next, spoiler gets more aggressive with the shaved pedestals and the extended lip (2 inches over stock), giving the setup a more aggressive look and function.  Last but not least, 6LE Designs notched the spoiler for rear window visibility, to help with daily drivability. The aggressive spoiler is 100% Made in America, and they have been privately labeled by RK Sport, so the quality is as good, if not better than OEM. Not to mention, the third brake light is included with the aftermarket spoiler, so just paint, bolt up, and enjoy!
