Hyperco's optimum body diameter (OBD) design concept is now available for 1/4 Midget competition. With design input from quarter midget chassis builders and race teams, Hyperco has developed spring designs that meet the specific requirements of modern quarter midget racing. OBD Hypercoils feature a unique design concept—Hyperco adjusts the body diameter of the spring relative to the end coils. The OBD design technique enables Hyperco to take full advantage of its extensive range of ultra-high tensile material by optimizing the applied stress through adjusting the spring's body diameter. OBD quarter midget springs are available in spring rate increments without tolerance overlap to offer predictable suspension tuning for a wide range of track conditions. Features include: more deflection, less weight, increased rate, linearity, more resistant to bowing, fits all standard hardware, and maintains free length/installed height.

Auburn Gear, Inc., a manufacturer of high-performance differentials, introduced its new MAX Lock Locker to the industry. The MAX Lock Locker fits inside the original equipment’s open differential case and automatically eliminates wheel slip in both two- and four-wheel-drive vehicles. The reasonably priced unit is precision engineered by Auburn to match OE case specifications and is designed to be easy for even a novice to install. Loss of traction can occur under any number of on- and off-road conditions, and with traditional two-wheel-drive and all-wheel-drive vehicles, when a wheel breaks loose and begins to spin, it draws power and effectiveness away from the other drive wheels. Aftermarket locking differentials can solve the traction problem for the most part, but a complete case replacement is often required and this can mean higher installation costs. The new MAX Lock Locker is economically priced and does not require OE case replacement. It's made to give the vehicle exceptional tractive performance, is designed for easy installation, and provides smooth, precise, quiet operation. The black-oxide-coated unit comes in a complete kit with easy-to-follow instructions. Installing the unit is as simple as removing the OE beveled gears, side gears and pinion gears from the existing diff case, and replacing them with Auburn’s dog clutches and spline couplings. Fifty-four SKUs of the new locker are scheduled for release in 2014 and will fit a broad range of popular vehicle makes and models reaching all the way back to 1955. The first-phase product release of 12 SKUs replaces a number of original Dana, Toyota, GM, Ford, Chrysler and Suzuki differential components. Compared to lockers requiring full case replacement, the MAX Lock Locker will be very competitively priced. Most four-wheel-drive and all-wheel-drive differentials track the path of least resistance, which means that one spinning wheel cannibalizes the power from the others. The MAX Lock Locker responds dynamically to tractive forces, automatically locking to deliver traction when needed and unlocking when wheel rotation must differentiate. Forrest noted that the unit optimizes traction so significantly that a two-wheel drive vehicle with a MAX Lock Locker can achieve greater traction performance than an all-wheel-drive vehicle with original equipment. Auburn’s MAX Lock Locker model numbers 544901, 544902, 544903, 544904, 544905, 54496, 544907, 544908, 544909, 544910, 544911 and 544912 have begun shipping.

Greaves 3D Engineering offers its latest model in its range of top quality pit and garage tools. The much acclaimed Greaves 3D Professional Tire Scraper is now available in 110-120 volt specification as well as the existing 220-240 volt configuration. The Professional Tire Scraper offers a practical, ergonomically designed solution to the management of part worn tires and is a much more efficient device than other improvised tools used for this process in the past.

Tilton Engineering’s 7.25" 2- and 3-plate clutch kits for 1979-2004 Ford Mustangs are its latest offering for road racers. Designed to be a direct replacement for the stock assemblies of the Mustang, these kits are designed to offer significantly lower weight and inertia than a standard 10.5” clutch-flywheel assembly. The low moment-of-inertia of these kit clutches provides faster engine acceleration out of corners and fast engine deceleration into them for improved braking, making them ideal for road racing applications. The clutch’s torque capacity (varies by plate count) is enough for most modified Mustangs, with the 2-plate cerametallic kit (P/N 56-200) sufficient for slightly modified cars and the 3-plate metallic (P/N 56-210) preferred for heavily modified cars. The clutches also provide a low release load for the Mustang cable-type release bearing system. The clutch kits include 7.25" clutch, disc pack, billet steel button flywheel, 44mm contact diameter release bearing and collar, and clutch bolt kit. They are designed for use with any high quality flexplate of the customer’s choice. Tilton Engineering produces a wide range of driveline and brake components, in-cockpit controls and starter motors. The company's products are primarily designed for racing use and can be found worldwide in nearly every form of racing, including NASCAR, IMSA, rally series and many more.
