Maintaining buses, trucks, and farm equipment--as well as large tire work, major engine teardowns, and spring bolt removal--requires a powerful tool. AIRCAT 1 in. aluminum heavy-duty pistol grip impact wrenches pack 200 to 1,850 ft.-lbs. of loosening torque into a hand-held air tool. These wrenches are built with a durable twin-hammer mechanism, and the D-type handle design includes an exhaust directed away from both the workplace and operator. They use a 1/2 in. NPT air inlet that allows for airflow pressure of 90 to 120 psi. AIRCAT impact wrenches are standard equipment in any mechanic's shop. If you perform heavy-duty machine or engine work, they're also an essential for you.

Stop worrying about input shaft failure when running the GM Powerglide in the most extreme applications. Sonnax offers the only big input shaft upgrade with custom components designed to work together for reliable performance. Whether you have an existing assembly or start from scratch in the gear ratio of your choice, it's the best way to connect huge power to Sonnax Extreme planetaries for great run after run with minimum downtime. The only way to prevent twist and breakage from massive torque is to increase the input shaft diameter, and the core of the big shaft system is big input shaft kit 353532-01K. The shaft strikes the perfect balance between strength and ease of installation with a 1 1/8 in. diameter and a unique, high-strength spline that still fits through the front sun gear. It delivers 35 percent more strength than standard 1 in. shafts, a dramatic upgrade for racers that want to take full advantage of the lightweight and efficient Powerglide automatic transmission. (Note: The Sonnax big shaft system for Powerglides requires changing to a 35-spline turbine hub.) Kit contents: * Shaft * Clutch Hub Big Shaft features: * Torsional, ringless design * Heat-treated, 300M steel with advanced processing * 35 splines (AOD-style) at converter Clutch Hub features: * 1.500 in. tall hub for use with 10-clutch setups * High-strength chromoly steel * Custom fit for the big shaft

One of the most popular Dual Sport bikes on the planet is the KTM 500 EXC-F—and now Yoshimura offers the ultimate exhaust option with their all-new Enduro Series RS-12 exhaust systems. Packed with features, the RS-12 Enduro Series offering comes with a USFS-approved spark arrester and massive gains in power. The KTM 500 EXC-F saw gains of 21.8 percent peak hp and 15 percent peak torque on the dyno. On the trail this translates to more 'raw grunt' when you need to get up that rock or over that log. On the street it provides more get-up-and-go to get to the next trailhead. Machined joints provide a more exact fit and longer durability between those muffler removal intervals and provides great tire and brake caliper clearance for an overall superior exhaust system. Key features and benefits: * Proudly designed, developed, and made in the USA! * Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximize capacity and incorporates a resonance chamber for managing sound and increasing usable power * RS-12's unique profile also provides more clearance for tire and brake caliper * Tapered muffler body inlet design enables the system to be pushed forward to help with weight centralization without sacrificing performance * Massive performance gains with refined power delivery * Just like the works systems Factory Racers use, the RS-12 systems utilizes precision machined joints that provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface; this translates into improved system life, fit and performance * New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters * Has a 'works-look' matte carbon fiber end cap with industry leading design, innovation, and detailing * Carbon end cap covers the RS-12 inner cap, thus improving looks, while providing easier service as compared to other sandwich mounting designs most commonly found in the industry * This system includes a USFS approved spark arrester Important Note: Factory turn signals must be relocated as the muffler outlet is inline of the factory turn signal location.

Failure of the intermediate stub shaft and direct drum are almost inevitable when transmissions are pushed to the limit. To maximize durability and improve clutch capacity in heavy-duty/performance vehicles, Sonnax offers Smart-Tech direct clutch drum and shaft kits, the first upgrade to eliminate every critical weakness. Most failures in these units occur where the direct drum and stub shaft connect. Even other aftermarket upgrades that rely on a heavy-duty shaft will sheer in this area under extreme conditions. Unlike two-piece assemblies, the all-in-one Smart-Tech easily handles the highest horsepower/torque levels. The unique one-piece clutch drum with integrated stub shaft is precision machined from high-strength steel to guarantee there are no splines to strip from the drum or weaken the shaft. The shaft itself is significantly thicker and 2 times stronger than the original. Due to its larger diameter, the integrated shaft must be used with the kit's custom, heavy-duty sun gear. Insufficient holding power is another area where many transmissions fall short, but installing thinner aftermarket steels and backing plates to increase clutch capacity isn't ideal. Those components increase clutch pack flex and heat build-up, making them the primary cause of repeat burn-up. To improve both performance and long-term reliability, the Smart-Tech's custom drum and piston hold an OE backing plate and seven OE frictions for 17 percent more clutch capacity than the six-friction stack-up. Sonnax Smart-Tech direct clutch drum and shaft kits feature: * One-piece design that eliminates weak point where drum splines strip and shafts break * Rugged shaft is 50 percent thicker and twice as strong as OE * Custom drum and piston deliver 17 percent more clutch capacity with optimum protection against burn-up * High-strength drum and shaft are precision-machined from hardened 8620 steel * Unique sun gear is precision-machined from 9310, heat-treated steel

Sonnax Smart-Tech input housing kits address the weak areas of 4-speed automatic transmissions. Flexing and bowing of OEM and other aftermarket backing plates is eliminated with Sonnax's heavy-duty bolt-on anchoring plates. Their unique design ensures even clamping of the 3-4 clutches in higher horsepower, higher pressure applications. By eliminating the 3-4 snap ring and using a thinner, yet stiffer apply plate, space is made available for additional frictions and steels. This makes it possible to simultaneously increase clutch torque capacity and eliminate the possibility of retaining ring blow-out. A steel reinforcement sleeve prevents breakage in the spline area. Housing fatigue/failure-resistance and housing life are significantly improved with a special treatment process that greatly reduces stress crack formation.
