Jam and Inject
Diesel Dynamics "Jammer" injectors give Cummins engines 50 to 175 more horsepower. These Jammer units are for '98.5 to '02 5.9L Cummins ISB engines in Dodge Ram trucks and RV coaches. The proprietary process used to create these injectors intricately machines eight orifices into the tips. Compared with the stock seven-orifice injectors, Jammers feature better atomization, faster fuel flow, and an enhanced spray angle. The increased number of orifices also enables the injectors to deliver more fuel, while still maintaining proper fuel pressure. The result is more power and improved combustion-chamber cleanliness. The Diesel Dynamics machining process also matches flow rate to within about 1 percent among injectors, further enhancing engine performance and smooth operation. The stock injectors can vary as much as 11 percent per set. Jammer Injectors are available in five configurations. Stage 1 increases horsepower by 65-plus in Cummins-powered pickups. Stage 2 adds as much as 85 horsepower, and Stage 3 increases horsepower by 100. For competition/off-road applications, Diesel Dynamics offers two pure-performance stages. Combined with other upgrades, such as aftermarket engine-control modules, a set of Stage 4 Jammer injectors will add as much as 150 horsepower, and the full-on Stage 5 kit can increase horsepower by 175. Across the board, Jammer injectors can also improve fuel economy by as much as 1-1/2 mpg, depending on individual driving style. The injectors can be installed by the average home mechanic. Using ordinary handtools, the competent do-it-yourselfer should be able to install a set in two hours or less. For more information, contact: Diesel Dynamics, Dept. OR, 6280 S. Valley View Blvd., Ste. 212, Las Vegas, NV 89118, (800) 628-8111,

Miller Electric Mfg. Co.'s new Big Window Elite Series of auto-darkening helmets offers exceptional performance in all welding applications and is specifically designed to satisfy the most demanding industrial requirements. Exclusive features include four independent arc sensors and a 30 percent larger lens window than Miller's standard helmets. The independent sensors improve out-of-position welding, while the larger window provides maximum viewing capability and retains a 4-ounce weight edge over competitors. The Big Window Elite features Miller's new replaceable battery/solar assist Performance Series lens technology. As incorporated in the Big Window Elite, this permits 3,000 hours of operating time before its two batteries need replacing. In addition, Performance Series technology offers excellent low-amperage TIG response and excellent DC-TIG inverter arc response, down to 5 amps or less. It also protects operators working in high-duty cycle applications. For comfort, Miller borrowed operating-room technology used by doctors and incorporated a form-fitting foam-rubber comfort cushion that attaches to the back of the head gear. The Big Window Elite helmet is available in black, two flame patterns, and a patriotic stars-and-stripes design. The Miller helmets are covered by an 18-month warranty.

Spray It, G
Gsport, a division of the Mr. Gasket Group, is proud to offer G-Muff to quiet down the cab of your pickup. G-Muff is a vibration-dampening compound in spray form that allows you to cover those hard-to-reach locations and extremely irregular shapes. This visco-elastic spray contains a significant mineral load that converts vibration energy into low-level heat, providing twice the dampening characteristics of other asphalt material. G-Muff also contains a corrosion inhibitor and improves car audio performance by reducing ambient noise levels. Use on hard-to-reach or difficult contours, such as inside the doors, under the kick panels, or on your subwoofer enclosures. It also works great on primed or coated metal, fiberglass, plastic, and wood. Each 20-ounce unit will cover 4-1/2 square feet and lays down a 0.032-inch-thick coat. For more information, contact: Mr. Gasket Group, Dept. OR, 10601 Memphis Ave., Ste. 12, Cleveland, OH 44144, (216) 688-8300,

Giant Motorsports' I-beam suspension kits for the '83-'97 Ranger consists of extended- or equal-length I-beams, radius arms, an engine cage, and all necessary rod end hardware. The kits feature billet end pieces that are a bit more user-friendly and allow for more spindle clearance. The construction of this kit is 1.75x0.120-inch chrome-moly tubing and covered by 3/16-inch plate on the main surface of the beam. An extra 1/8-inch plate is layered between the billet end piece and the main plate for added strength. The 1-1/4-inch rod end joints are used with a stainless-steel offset and misalignment spacers to keep the jam nuts away from the crossmember. Giant I-beams are constructed a little taller for additional strength. The equal-length kit includes bolt-on beam pivot brackets. Giant's beam pivots are great for mounting to existing frame holes with minor drilling, which makes for easy installation. Equal-length beams are available 8, 9, or 10 inches wider per side. Extended beam options are 7-1/2 or 8-1/2 inches wider per side. Giant's extended-beam front suspension kit is great for mounting in stock locations. The main plate work of Giant's radius arms is constructed out of 1/4-inch plate, with deeper pockets for beam clearance and more offset for the tire and steering ratio. The radius-arm pivot boxes are constructed from 1/4-inch plate and body mount between the transmission crossmember so they're able to fit any Ranger setup. Giant's radius arms use 1-1/4-inch Heim joints and stainless-steel spacers. Designed for a 14-inch coilover shock, the engine cage supports the upper mounting location of the coilover and readily fits without disrupting the stock-engine-compartment component's mounting location. The engine cage can work with stock beams, or any company's widened beams. For more information, contact: Giant Motorsports, (949) 369-7223,

Pump Up the Volume
Owners of the '98.5 to '04 Dodge Cummins pickups and pusher RVs can give their engines as much as 70 more dyno-proven horsepower and 220 lb-ft of towing torque in only a few minutes. The Edge Products EZ Module works with the factory drivetrain computer to enhance fuel and ignition curves and increase turbo boost. Edge Products employs state-of-the-art software on premium-quality Motorola chips in every EZ Module to obtain real-world power gains safely and reliably. The plug-and-play installation takes about 10 minutes. Factory connectors for the MAP sensor and ECM data link plug into the EZ Module, and the Edge unit then sends optimized signals to the engine through its wiring harness, which has factory-style connectors. The waterproof EZ module attaches to the fuse cover with the kit's enclosed Velcro. An included brass elbow replaces the OE wastegate pressure-sensor fitting to allow the turbo to produce greater boost. Real-world improvements include increased hill-climbing speed when towing loads up grades. Fuel economy often improves in the process.

Two Cummins EZ applications are available. One covers '98.5 to '02 Cummins engines and adds 65 horsepower and 185 lb-ft of rear-wheel torque. The Edge EZ for '03 to '04 Cummins (non-H.O. engines) offers four different user-selectable power modes: 40 horsepower/150 lb-ft; 50 horsepower/ 180 lb-ft; 60 horsepower/200 lb-ft; and 70 horsepower/220 lb-ft. Overall, Edge Products designed the EZ Module to be the quickest way to dramatically improve diesel power. For more information, contact: Edge Products Inc., Dept. OR, 1080 Depot Dr., Ogden, UT 84404, (888) 360-3343,
