When you install the Velineon Brushless Power System, you’ll experience a giant leap in speed and power. The Velineon VXL-3s speed control and 3500 motor replace the XL-5™ speed control and Titan® 550 motor to more than double the Slash 2WD and 4X4’s top speed and deliver wild dirt-roosting torque. All Slash trucks are Brushless Ready from the start so no modifications are needed to go brushless. Installation is easy, and waterproof construction means you can experience Velineon power in all types of wet conditions, including mud and snow. You can even trade in your brushed equipment for a discount on a Velineon system with the Power-Up Program.

Show-car style graphics have traditionally required an eye for design, hours of masking, and airbrushing skills, but Traxxas makes it easy to get professional results in just minutes with a ProGraphix body and one or two cans of Traxxas ProGraphix paint. The intricate body design is applied for you, all you have to do is spray the clear areas with your favorite color. There’s no cutting or drilling required—all ProGraphix bodies arrive fully trimmed and with body holes in place for a factory fit. Overspray film protects the body as you paint, and a complete set of decals with windows, logos, and detailing completes the premium ProGraphix transformation.

If you’re out for peak racetrack and street performance with your Slash or Slash 4X4, lowering your truck’s center of gravity (CG) is the proven way to achieve tighter handling, greater responsiveness, and higher corner speeds. Traxxas makes it easy to lower your Slash’s CG with 2WD- and 4X4-specific conversion kits that include everything you need to lower the battery and electronics by a full inch for dramatically improved driving feel. Each kit features a new low-slung chassis and all the required parts and hardware to complete the conversion. The 2WD kit even includes low-CG-optimized front springs for track-ready handling

Give your 2WD Slash sharper steering, enhanced durability, and anodized color with genuine Traxxas aluminum bellcranks. Machined from solid 6061-T6 aluminum, these rugged bellcranks provide flex-free control no matter how punishing the terrain. Ball bearings support the steering posts for ultra-smooth action and super-precise control, and the bellcranks arrive fully assembled and ready to install. The package includes hardware with pre-applied threadlock and illustrated instructions.

Traxxas Heavy Duty suspension arms boost strength and durability as they add a blast of color to Slash and Slash 4X4 models. The new arm design is optimized for stiffness and resiliency while maintaining the Slash and Slash 4X4s proven suspension geometry. The proprietary Heavy Duty composite formulation is incredibly tough—even in cold temperatures that can make molded parts brittle. HD arms are available in black, blue, green, white, orange, or red and you can completely outfit your truck in just a few minutes.

Metal servo gears offer superior strength to outperform and outlast molded gears, and Traxxas makes it easy and affordable to go metal with the 2075X servo. The servo’s 125 oz-in torque output gives Slash and Slash 4X4 all the steering muscle required for high-traction action. Precision metal gears and ball-bearing-supported output shaft deliver severe-terrain durability and waterproof construction keeps your Slash steering strong even in mud and snow.

The Big Bore 4-shock set includes everything you need to replace the stock Ultra shocks with feature-packed aluminum dampers spec’d for competition. Hard-anodized aluminum bodies, slippery PTFE-coated shock bores, and slick titanium-nitride coated shafts are all standard. The high-tech coatings give Big Bore shocks incredible durability and near frictionless operation for ultra-smooth damping, consistent bump and jump control, and long-lasting performance. Big Bore shocks arrive fully assembled and ready to fill with the included 30-weight shock oil. Progressive-rate springs for 2WD Slash models are installed; for Slash 4X4 installation, use your truck’s included springs.

Sand, snow, and other soft conditions become a whole new way to have fun when you install high-performance paddle tires! The Traxxas paddle tread features thick scoops reinforced with strengthening ribs, and TSM®-rated construction ensures a super-strong tire-rim bond that holds tight no matter how wild you get with your brushless-powered roost sessions. Traxxas short-course paddle tires are sold in pairs with foam inserts and mounted to stylish split-spoke wheels. Add a pair to the rear of your 2WD Slash, or put paddles on all four corners of your 4X4—the SCT wheels have the correct offset for both applications.

The Drag Slash’s all-new Magnum 272R transmission is an outstanding upgrade for all Traxxas 2WD models, including the Slash series. Tune the 272R sealed bevel-gear differential by altering oil viscosity with Traxxas high-quality differential oils. Differential access is fast and easy via the gearbox’s quick-access hatch. The all-new case halves feature reinforced arm mounts, a 3.2 mm aluminum motor plate is standard, and the all-metal geartrain features an integrated top gear and hardened-steel input shaft for unbeatable strength and durability. For maximum durability and competition-grade efficiency, the Magnum 272R transmission is a must-have.

Traxxas aluminum wheel nuts in bright anodized colors are a fun and inexpensive way to dress up your Slash, but they’re not just for looks. Sharp serrations machined into the nuts’ flanges bite into the wheels to hold extra tight, so your Slash won’t lose its shoes if you get a little lax in regularly checking your wheel nuts or rough terrain and big brushless horsepower tend to loosen your wheels. Choose black, red, green, or blue and hang loose knowing your Slash’s nuts will stay tight.
