Check out the new Cat4ward Headers for all '91-'99 Jeep vehicles equipped with the 4.0L I-6 engine. Built from 409 stainless steel, this header is 50-state emissions-legal and comes with JBA's Sealing Dome collector. The flanges are laser cut from 1/2-inch material. These headers are engineered as a direct replacement for the restrictive crack-prone factory manifolds. JBA also has optional crossover pipes, performance exhaust systems, and ignition wires available for 4.0L Jeeps. Info: JBA Performance Exhaust, 800/830-3377, www.jbaheaders.com

Dynatrac announces its new DynaLoc locking hub kits for Dana 60 axles. Truly the first new locking hub design in 20 years, DynaLoc, made 100 percent in the U.S., is an essential component of reliable four-wheeling. Made from heat-treated, chromoly steel, the unique gear-tooth design will not disengage under high torque load and is three times stronger than other Dana 60 locking hubs. The low-profile knob assembly decreases impact with rocks and other obstacles while the stainless steel bezel resists impact and scrapes when contact is made. For more reliable operation, the DynaLoc defaults to the locked position as opposed to other popular hubs that default to the unlocked position. Replacement kits to upgrade OEM Dana 60 axles using 35-spline axles will be available, and for the first time ever a version for 40-spline axles will allow the economy, safety, and convenience of unlocking for even the most extreme off-road vehicles.

Dynomax just came out with a new exhaust cut-out "Y" pipe designed to work with DMH Performance Exhaust cut-out valves. Exhaust cutouts let the engine breathe easier by dumping exhaust gases out after the headers or manifolds, effectively creating an open exhaust system. At the push of a button, you can open or close the DMH valve instantly. The "Y" pipes are I.D.-sized for simple slip-fit installation with no welding required. The setup uses a loose flange at the valve side of the Y. This makes installation in tight spaces a snap. Each part is sold separately through each company. Sizes range from 2.25-inch all the way up to 4-inch for diesel applications. Info: DMH Performance, 513/753-3866, www.dmhperformance.com; DynoMax, 734/384-7806, www.dynomax.com

Owners of '07 GM 2500- and 3500-series diesel pickups can go that extra mile by installing a larger replacement fuel-tank system from Transfer Flow.

There's also a 56-gallon replacement fuel tank for crew-cab and extended-cab pickups with 8-foot beds.

JKS now offers heavy-duty extended brake lines for the new Wrangler JK. These 22-inch hoses virtually eliminate volumetric expansion to provide an immediate improvement in pedal feel and response during hard braking events. The hoses are made from multilayer Kevlar, elastomer, and stainless steel braid. A translucent UV-protected vinyl jacket adds a final layer of protection. These hoses are pressure-tested to 4,500 psi and surpass all DOT and MvSS-106 requirements. Info: JKS, 308/762-6949 www.jksmfg.com

In off-road racing, Zoo Road is known as one of the most brutal whoop sections on the whole Baja peninsula. Donahoe Racing has been testing its newest shock edition there for the past year. It was designed to handle the toughest conditions on earth. The Zoo Road shock features an adjustable ride height of up to 3 inches, a 200psi nitrogen-charged external reservoir, steel braided reservoir lines, a revolutionary new high-flow piston design, large 1 1/4-inch Nitro Steel shock shafts, and a huge 4.5-inch body. All components are CNC-machined from 7075 and 6061 T6 aircraft-grade aluminum, and the giant 7-inch-diameter dual-rate coil springs provide 7 to 9 inches of total lift height.

Tuffy Security Products has just released a new Security Drawer (PN 140) for the Jeep Wrangler JK. This Security Drawer provides lockable storage for valuables. Included in the mounting of the drawer is a riser system, which provides the option of easily mounting the drawer higher (approximately 4 inches of clearance) so other objects can be stored underneath. The JK Security Drawer mounts easily in the four-door JK with the rear seat in place or in the two-door JK with the rear seat removed. It also works with the factory subwoofer speaker in place. Constructed of heavy-duty 16-gauge steel with an attractive textured black powdercoat finish, each drawer is supported by a new drawer slide system incorporating smooth-operating, sealed stainless steel roller bearings. Each drawer also features Tuffy's patented Pry-Guard II Locking System. Info: Tuffy Security Products, 800/348-8339, www.tuffyproducts.com
