Kyosho Ultima SC-R race kit

Kyosho have Introduced the SC-R race kit complete with proven parts from the Ultima RT5 and RB-5SP. Since its arrival to the SC scene the Kyosho SC Readyset has proven itself by winning every major race across the U.S. since its release, winning the Silver State, Cactus Classic and most recently the SC Showdown. Kyosho has produced a 100% race kit with a ton of high performance components. The Ultima SC-R is equipped with some of the best option parts that Kyosho has to offer like velvet coated shocks, ball differential, universal swing shafts, steel suspension bushings, adjustable hard-rod ends and teflon shielded bearings. Available in late July.

Velvet Shocks – Kyosho is well known for silky smooth shocks and the new Triple Cap shocks included with the new Ultima SC-R are no exception. The shock body consists of three major components a top cap, velvet coated threaded bodies, and a lower cap. The velvet coated shock bodies feature a threaded spring pre-load collar for quick and easy adjustment. The threaded adjuster features an O-ring that prevents the preload settings from moving, which ensures consistent performance from start to finish. The lower shock cap allows for quick and easy maintenance of the double O-ring seals.

Ball Diff – Features an externally adjustable internal ball differential that uses standard 3/32–inch diff balls and 1/16–inch thrust balls. Includes tight–fitting molded dust cover to protect pinion and spur gear.

Universal Swing Shaft – Equipped with universal swing shafts for better power transfer and maximum efficiency.

Hard Adjustable Rods – Featuring Chromoly turnbuckles, the use of stronger material means the turnbuckles can be made lighter and stronger than the original steel units.The rod ends feature a stronger material that is more durable and resists contamination from dirt. This means that the rod ends stay tighter and are less likely to be damaged or separated from the ball stud in the event of a hard crash.

Teflon Shielded Bearings – Ball bearings are the standard for reducing friction and wear, and to increase efficiency. It’s nice to know that the Ultima SC-R is equipped with a full set of 18 Teflon-sealed ball bearings used throughout the drivetrain and transmission to keep things running smooth.

Steel Suspension Bushings – Give you a much more precise and consistent suspension response.

Composite Chassis – The chassis plate is 40mm longer then the RT5. Light and strong, featuring a specially formulated carbon fiber composite for the best balance of performance and durability. Strategic braces molded into the chassis enhance the stiffness without adding any unnecessary weight. Separate front and rear clips allow fast and easy removal of the front and rear end of the car, which makes maintenance and repair much easier. Designed to accept stick packs and 2 cell lipo packs, the SC chassis features an adjustable battery mounting position that allows you to shift weight bias to suit track conditions and your driving style.

Rear Suspension – The rear suspension is symmetrical so a single replacement arm can be used on either side of the truck, saving money and space inside your pit box because you don’t need to carry as many replacement parts. The inside of the arms are attached to the chassis using separate suspension mounts, which will allow anti-squat adjustment. Vertical ball studs for the both inner and outer rod ends of the upper link means the rear suspension geometry can be fine tuned with shims.

Front Suspension – Symmetrical suspension arms connect to a narrow front bulkhead. The bumper/skid plate, suspension block, nose plate and front bulkhead all come together to form a very rigid assembly, to which the front suspension arms mount to. The standard position of the suspension mount produces 25 degrees of hinge pin angle in the front arms, but simply flipping the suspension mount increases hinge pin angle to 30 degrees. The added flexibility of having adjustable hinge pin angles means you have more options when it comes to setting up your truck. Like the rear arms, a single replacement arm can be used on either side.

Floating Axles – While floating axles ride in bearings that are mounted in the hub instead of the wheel, this moves the weight of the bearings inboard for extremely responsive suspension. The bearings are under less stress, and they’re better shielded from the elements.

Steering Assembly – The steering bellcranks are mounted on the chassis at the same angle as the suspension arms. This eliminates bump steer and produces more accurate Ackermann geometry throughout the entire range of steering motion. The steering plate (center link) features horizontally mounted ball studs, which mean the Ackerman can be fine tuned by using shims behind the ball studs offering a nearing infinite range of adjustments.

Captured Hinge Pins – A simple button head screw captures all the outer hinge pins of the Ultima SC. The rear inner hinge pins are truly captured between the suspension mounts, and the notched inner front pins are secured with a setscrew through the front suspension mount. This means that the hinge pins are much more secure and less likely to come loose.

Kit – Giving you a 100% chassis that you build from the ground up. You have full control of your race machine, not just tuning but also building it. Legendary Kyosho performance at your finger tips.
