In Depth Features:
  • Split Chassis: The composite chassis frame has a split design with a separate front part and rear chassis plate. The split design allows the entire rear suspension to be mounted in either standard position using the rear chassis plate, or to be placed lower by mounting the rear suspension directly to the aluminum chassis. Mounting the rear suspension directly to the chassis requires optional (not included) rear suspension holders XRA363311 & XRA363321. The direct mounting of the rear suspension increases traction and is recommended for low-traction tracks. The rear of the chassis features positions for additional optional weights which allow for quick and easy weight balance adjustment. The split chassis is compatible with both XB4 & XB4 2WD.
  • Suspension Arms: The suspension arms feature the innovative SFA™ (Suspension Flex Adjustment). Whether you are racing in low- or high-traction track conditions, you can easily adjust the flex of the arms by adding optional (not included) graphite stiffeners which change the stiffness of the suspension. The arms feature 4 holes where the optional graphite stiffeners are mounted, and the areas around the holes are strengthened for maximum durability.
  • Optional SFA™ Graphite Stiffeners: Innovative and unique SFA™ graphite stiffeners allow for super-quick suspension flex adjustment to easily adjust the traction of the car in various track conditions. Made from 1.6mm thick high-quality CNC-machined graphite material, the stiffeners can be mounted or removed by only a few screws. Whether you drive in low- or high-traction conditions, with the graphite stiffeners you can quickly and easily adjust your car to suit changing conditions. At the beginning of a race event when traction is low, the arms are used without the SFA™ graphite stiffeners. As traction increases, the suspension can be made stiffer by mounting the SFA™ graphite stiffeners for more stability and easier driving characteristics. The graphite stiffeners give the car maximum stability in chicanes and allow for easier and smoother steering. The stiffeners are not included and are an optional part.
  • Wheelbase Adjustment: The suspension arms are narrower which allows for quick and easy wheelbase adjustment. Using included 2mm shims, both front and rear suspension arms can be moved either forward or rearward to adjust weight balance depending on track conditions. By moving the arms to the front, the balance and weight of the car are transferred more to the rear; this is recommended for medium– and high-traction conditions. By moving the arms to the rear, the balance and weight of the car are transferred more to the front; this is recommended for medium- and low-traction conditions. The wheelbase shims allow not only to move the suspension forward/rearward, but also allows the wheelbase to be adjusted shorter or longer for fine set-up tuning under various track conditions.
  • Variable Shock Mounting: The design of the rear suspension arm allows very practical variable position of the rear shock absorbers. Depending on track conditions, the rear shock absorbers can be installed either in front or behind the shock tower.
  • Slipper Clutch: The power from the motor is transferred to the drivetrain via an adjustable central slipper clutch for quick and easy tuning. The lightweight slipper clutch plates have a machined relief that decreases the friction surface which assists with clutch slip adjustment. With the redesigned plates, the pressure of the plate is on the circumference of the clutch pads, which increases the efficiency. The slipper clutch pads are produced from ultra-efficient SLS material with very high slip efficiency and allows very precise adjustment of the slipper clutch. The updated clutch spring is much stronger which helps improve consistency and gives ultra-fine slipper clutch adjustment. The clutch outdrives are super lightweight and manufactured from HUDY Spring Steel™ and are additionally hardened for extra life and reliability. The slipper plates are machined from premium Swiss 7075 T6 and additionally hardened and with a black final surface treatment.
  • Off-set Wheels: The front wheels feature +1mm offset which makes the front of the car wider and more stable.
  • Bulkheads: Front & rear bulkheads were reinforced to withstand rigorous impacts and abusive racing conditions. The diameter of the holes for ball-bearings was refined to minimize ball-bearing play which results in increased lifespan of the gear’s teeth and minimizes stripping.
  • Shock Towers: Front & rear shock towers were redesigned and reinforced. Machined from premium-grade 3.0mm graphite, the shock towers are lightweight and strong and have multiple shock positions as well as multiple roll center adjustment positions. The rear shock tower holds the wing mount.
  • Differential Outdrives: Both front & rear differentials feature reinforced diff outdrives to increase reliability.
  • Differential Bevel Gears: To increase lifespan and reliability, both front & rear differentials include reinforced diff bevel gears.
  • Ball Joints: To increase reliability, the ball joints were redesigned and reinforced.
  • Top Deck: The top deck was reinforced for increased reliability and other small details were improved for a more precise fit. The top deck is machined from high-grade graphite, and its main design purpose is not only to hold the body mount but also to reinforce the chassis assembly by connecting the front diff bulkhead with the central drive system. The top deck captures the central drivetrain bearings and holds them in place in their supporting bulkheads.
  • Shock O-Rings: To improve shock sealing, the upper cap O-rings are included in the shock absorbers.
  • Shock Tower Protector: In addition to the reinforced front shock tower design, the XB4 includes an additional shock tower protector which can be used at extremely abusive tracks.
  • Optional Ball Differential: The optional ball differential was designed and is suggested for low traction track conditions. Externally adjustable ball differential is machined from HUDY Spring Steel™ and additionally hardened for extra durability and long lifetime. High-quality carbide thrust bearing is included for smooth operation and the carbide balls ensure ultra-smooth running. The ball differential comes factory pre-assembled.
  • Additionally Included: HUDY graphite grease, silicone Oils, authentication certificate, set-up sheet, parts list & exploded view, decals.

XRAY XB4 2014 1/10 Electric 4WD Buggy Kit
Hands down the best buddy I have ever owned. I have had drove the B44, had the Kyosho and 410v3 and also just got the Hotbodies d413 and this buggy is x2 better then them all. Its so smooth and can take a beating like no other. The plastic and hudy steal in top notch. not to mention the support they offer online. I find myself being able to push it more and crash a lot less. my only wish is it had some type of center diff, but I think xray knows better then I do. if you want to move up a couple spot at your local club race I will bet my house this buggy can help you do it..

I have built over a hundred kits in my 20+ yrs in the hobby. This is easily one of the best for fit and finish. Everything goes together so well. You do pay a little bit more for stuff from Xray/Hudy, but it really is worth it. The quality of the materials in this kit are second to none. I like that several of the major suspension components (front arms, steering blocks and rear hubs) are designed to be universal (left or right). This keeps the need carrying multiple sets of spares to a minimum. One minor thing to be aware of is that there are a couple little things in the manual that are not in the 2014 version of the kit, but if you have at least an intermediate experience level with kit building you'll figure it out. Overall, it’s a great kit. I'll update this review concerning how the car drives once I hit the track next week. :) May 28, 2014: So just wanted to add an update for this kit. Wow, what a great car. It handles great and is quite stable and easy to drive. It is sensitive to setup changes and easily tunable. And this thing is a tank. I have had several hits to the front A-arms that would have sheared off a B44.2 arm, but this thing just keeps going. The composite material used throughout the car is rigid, but not brittle. I am totally satisfied with this car. I highly recommend it! Two thumbs up! :)

This Kit is the best buggy I have ever owned, strong, reliable and very fast. The only let down are the plastic drive gears, as they strip very easily
