Motive Gear Performance ring and pinions are perfect for dedicated racing or off-road vehicles. Their gear sets are made from first-run steel, they never use recycled metal. This allows Motive Gear Performance ring and pinions to handle the extreme torque from high-horsepower racing engines. Extensive engineering, computer-controlled heat treatment, superior strength, quality and the widest selection of racing gear ratios, makes Motive Gear Performance ring and pinions the clear winner! Engineered to the highest standards, every Motive Gear Performance product goes through rigid quality control processes in their in-house lab. Motive Gear Performance also offers a lightweight alternative to standard ring and pinion gear sets. Their AX Series ring and pinions are designed to increase horsepower and efficiency by removing rotating weight. Professional race teams have used custom-lightened drivetrain parts for years, resulting in faster times and more wins. The AX Series gears from Motive are lightened during the manufacturing process; this results in gear sets that have been engineered, not modified. Computer-controlled heat treatment, index tooth spacing, and CNC machining all go into AX Series performance gear sets. Motive Gear Performance: What the pros run!

Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.

Years after releasing their successful Rock Assault 9 axle housing, Trail-Gear decided to add a Toyota 8 in. version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles; however, they're built to accept the popular Toyota 8 in. differential. These housings have been tested in W.E. Rock, CalRocs, and King of the Hammers—so you know they'll stand up to the toughest terrain on earth. Trail-Gear started with a 1/4 in. thick formed shell for the center section made from A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi. All of this is attached to an equally strong 1/2 in. thick faceplate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment System, giving the tubes superior support and engagement into the center section. Trail-Gear also faces the center section to ensure your differential mounts flush against the axle housing to prevent any leaks. Rock Assault Fabricated 8 Housings are offered with 3.5 in. O.D. axle tubes with your choice of 1/4 in. or 3/8 in. wall thickness. NOTE: The housing is shipped with no ends. Housing ends must be sourced and installed to complete axle. Portal style ends are commonly used for this application.

A 4x4 and traction go hand-in-hand; however, standard (open) differentials allow each wheel to turn independently to eliminate binding in turns. Off-road, this becomes a problem as engine power takes the path of least resistance—to the wheel with little or no traction. Limited slip differentials offer some improvement, but too often the slipping is not "limited" enough to maintain forward progress. Automatic locking differentials also have disadvantages; noisy when disengaging, they can also upset on-highway driving characteristics. Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ a 12 V ARB air compressor (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential. When activated, the Air Locker prevents the differential gears from rotating and the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional open differential. ARB Air Lockers are available in over 100 configurations for a wide range of vehicles and can be installed in both front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required, apart from those necessary for fitting a standard differential. ARB also offers three compressor models suitable for Air Locker operation, two of which can be used to inflate tires and operate other equipment. Additional features of ARB Air Lockers include: * Vastly improved traction means less reliance on momentum, reducing the likelihood of vehicle damage * Easy, convenient operation without leaving the comfort and safety of the driver's seat * Ultra durable and extremely strong; only the highest quality materials used in construction * Patented gear technology and 2-piece design ensures optimal locking strength * Forged gears provide superior strength and durability * Incredibly simple, yet effective, design employs minimal moving parts for maximum reliability * Thoroughly tested and proven * Most sold as kits with differential, activation switch, solenoid valve, air line, and bulkhead fittings * Front and rear Air Lockers available for most makes and models * For 4WD and 2WD applications * Easy maintenance; no special additives required * Also offered in ARB Traction Packs that include two Air Lockers, a compressor, and accessories for tire inflation

ACT Mod-Twin 225 heavy-duty twin-disc street clutch kits are designed to tackle aggressive launches and rapid shifting of high powered AWD's—by combining twice the organic friction surfaces with a no-nonsense solid mono-drive hub in a completely modular design. Each diaphragm spring endures an exclusive 4-stage heat treating process to provide a more consistent light pedal feel. The puck-style friction plates, with high-quality organic materials, deliver high friction coefficient, superior heat capacity, and long clutch life. These friction plates uniformly transfer torque to a mono-drive chromoly hub, which is heat-treated for strength and durability, extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. Clutch kits are available in different styles and other options for fitment on countless vehicles from the early 2000s and up. Features and benefits: * Recommended for drag, road, or rally racing use * Predictable aggressive engagement, light pedal effort, smooth shifting, possible start-off judder with OE to mild transmission gear noise * Forged aluminum cover, mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin performs and survives under the most demanding conditions * Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances * 100 percent clamp load tested, balanced, and SFI certified Kit contents: * Forged aluminum pressure-plate cover * CNC-machined and dynamically balanced flywheel * Diaphragm spring and face * Puck-style organic friction plates * Available with sprung or unsprung mono-drive hub assembly * Floater * Patented mono-Loc collar * Release bearing * Alignment tool and pilot bearing (if needed) Note: Mod-Twin clutches are fully rebuildable and most components can also be ordered separately, if you do not need to purchase complete kit.
