Want to know how to get your stuff in New Products? If you have a new truck- or 4x4-related product you'd like us to help you debut, e-mail an image and some text to Please have all images be no less than 1600 x 1200 pixels (or two megapixels) and be saved as a TIFF, an EPS, or a maximum-quality JPEG file so our art director doesn't shoot us. We can't use images off of any Word documents or Adobe Acrobat files, so be sure to include a separate image in the proper format, or it won't be run. Thanks again. We love seeing all the new stuff you guys come up with!

Looking for the next step up on your '05-and-up Super Duty? Check out Pro Comp's new Double XX dual coilover kit that puts two 2.75 remote-reservoir coilover shocks in the front. Offered in both 6- and 8-inch versions, this kit gives you new tubular radius arms with pliable rubber bushings for a good ride, and complete replacement rear springs (not just blocks). To absorb rear hops, a pair of MX6 six-way adjustable shocks are put on duty, while 3/16-inch coil towers hold four remote-reservoir shocks up front. Information: Pro Comp, 800.776.0767,

Pro-Stop brake rotors are now available with a cadmium plating for most late-model SUVs and trucks as a premium upgrade over the tired factory rotors. The hole patterns are carefully engineered and precision-machined to enhance out-gassing and improve pad cooling on the North American-made rotor casting. Since the rotors are cadmium plated, they'll resist corrosion and ugly rust on the rotors. Information: Pro-Stop Drilled,

Want the ultimate bling engine for your ride? Check out Katech Performance's line of LS7 engines. The Track Attack is a 7.0L choice for off-road use that combines a high-output camshaft and valvetrain mods with 12:1 or 14:1 forged pistons. You can get it with an electronic or mechanical throttle control. Information: Katech Performance,

The Dick Cepek Mud Country name is back, but on a whole new high-void stepped-lug tire. The radial construction tire offers a true mud-terrain tread, but with a generous amount of siping to provide great rain and snow traction. The tires are available in 21 sizes from 31 to 40 inches tall, fitting on 15- to 20-inch wheels. They'll be available at your nearest Mickey Thompson/Dick Cepek tire dealer by the time you read this. Information: Dick Cepek Tires & Wheels, 800.222.9092,

We've barely seen these on the street, and Dynomax already has a new exhaust system for the '07 Tahoe/Yukon. The after-cat system comes complete with a flex coupler, 3-inch aluminized tubing, a 4-inch tip, and an Ultra Flo welded muffler. Dynomax's dyno tests quote an 8hp gain at peak performance while also matching that number in torque. Information: Dynomax, 734.384.7806,

CAGE Offroad has developed some tubular radius arms that can help you ditch IFS, leaf springs, twin-traction beams, or those old factory radius arms on Broncos. With the optional axle bracket that you can weld onto any axle, you can make yourself a front- or rear-link suspension without all the difficulties in setting up a link suspension. The radius-arm brackets bolt easily onto any 4x4 frame and offer clear advantages to rockcrawlers and desert runners alike. The 2x313-wall tubing is combined with 1/4-inch laser-cut plating and 1 1/4-inch Teflon rod ends. CAGE also has progressive-rate springs to help finish off the package. Information: CAGE Offroad Products, 866.587.2243,

Trail Master's newest kit is this '07 Suburban/Yukon XL that will get you up in the air 4 to 6 inches. The kit utilizes precision CNC-machined ductile cast-iron steering knuckles with laser-cut crossmembers to provide great suspension geometry. The kit will allow you to get 33-inch tires on, and 35s with a little trimming. Information: Trail Master Suspension, 928.636.7080,
