Bilstein's Shane Casad dropped some pre-Expo hints about the new 9300-series bypass shock. "It looks like something out of a science-fiction movie," went the claim. We weren't disappointed. The 9300, dubbed the Blackhawk, is a revolutionary design in the world of hard-core off-road shocks. The Blackhawk uses an aluminum shock body for light weight and quick heat dispersal. Aluminum's high heat-dispersal rate is augmented by using cooling fins on the shock body, keeping the shocks running as much as 100 degrees cooler than comparable-size steel-bodied bypass shocks. Cool-running shocks provide more consistent suspension action and allow a truck to maintain speed in the rough. In the past, aluminum shock bodies were a disadvantage because the bores wore more quickly than steel. The Blackhawk's answer to this drawback is a special hard coating on the piston bore. The coating is so hard that it can't be cut with a hacksaw, or even with lathe tooling. Anything else? The Blackhawk's bypass tubes have distinct detents, making tuning easier and more accurate. The remote reservoir uses an anticavitation valve, allowing nitrogen to run at low pressures, which further promotes smooth, consistent shock action. We're sure that the only thing better than eyeing the Blackhawks will be riding in a Blackhawk-equipped truck.
Dynatrac's Pro Rock 60 is tough to beat. Combining the ruggedness of a 9-3/4-inch ring gear with the strength of 332-X U-joints, the Pro Rock 60 actually has more ground clearance than a standard-issue Dana 44. Dynatrac can build a Pro Rock 60, standard Dana 60, Dana 44, and its beyond-overkill Dana 70 and Dana 80 axles to customer's needs, including widths, wheel bolt patterns, suspension-attachment points, and traction-aiding devices. Yes, all this performance does come at a price, but off-roaders who choose to lighten their wallets at Dynatrac come away with smiling faces.
Sway-A-Way's red RaceRunner shock lineup has been expanded, with models featuring piggyback reservoirs that rotate 360 degrees for easy mounting. This ultra-cool 4-inch external-bypass model is also a new addition to the product line. The girth of the shocks and extra volume of oil that goes along with the added diameter promise fade-free performance on the heaviest of off-road trucks. The size was impressive, but we thought you'd be even more impressed with a close-up view of the gorgeous TIG welds that fuse the bypass tubes together.
