JConcepts BK Design 13mm Shock Pistons

A project from Brian Kimwald himself, BK Design Shock Pistons are now available as an option for 13mm shocks through JConcepts. The BK piston, machined in low friction Delrin material has opened a can of goodness racers have only heard about, until now. The prototype slotted piston, machined by BK using equipment purchased exclusively for the master of all RC trades, was for sure a late-night project. During 2016, finding grip with newly released mid-motor vehicles was a vicious hunt for low-traction dirt conditions. As track conditions advanced, finding grip wasn’t necessarily as high a priority, hence the delay in the BK piston introduction. However, as the hands of time move forward, vehicles are once again looking for an edge in grip handling due to their advanced corning abilities. The all-precision machined item has the makings of the latest winner from the JConcepts Speed Laboratory and can be tuned by the user. The latest BK pistons arrive with plenty of pre-drilled combinations. Test drivers have reported increased vehicle grip while utilising the exclusive design. The BK channel in the piston increases the volume of oil in the shock body acting as another chamber in the shock body to add consistency to the mechanism. During compression and rebound, a lot of disturbance is created inside the working area of the shock. The action of a traditional piston is very top to bottom with pass-through only allowed through dedicated holes and around the perimeter due to blow-by. With this design, the piston is passing fluid through 2 separate channeled sections while the entire disturbance area rests in oil which helps compartmentalise all activity.

JConcepts 2.0″ X-Bite 4WD Front Tyre

JConcepts has introduced their all-new X-Bite 1:10 4WD tyre which the Florida based company say is ‘a fresh pin tire option developed for outdoor racing and future events around the world’. Produced specifically for 2.0” 4WD front wheel applications, the X-Bite draws influence from the successful Dirt Bite 1:8 offroad tyre. Tipping a cap to pin tyre trends from the early 2000’s, the X-Bite delivers a unique combination of modern performance and nostalgic styling. It features an aggressive radius pin layout loaded with square pins for exceptional forward traction and balanced side-bite on loose and evolving surfaces. At the center of the tire, an integrated “X” design helps define the tire’s character while assisting stability and feel during acceleration and directional changes. Designed for racers searching for grip before the groove develops, the X-Bite excels on loose, damp, and natural outdoor surfaces that have yet to take on rubber. Whether conditions are fresh, rough, or moisture-packed, the X-Bite provides confidence and consistency lap after lap. Each X-Bite tire includes Dirt-Tech closed cell inserts for additional support, consistency, and long-lasting performance in low traction conditions. The carcass is smooth without any features and provides a steady contact patch to included inserts. Combined, these details provide racers with a more planted and predictable feel when pushing through demanding outdoor conditions. For the ultimate performance and control, JConcepts recommends pairing the X-Bite with genuine Mono or Pioneer wheels.

JConcepts Cat PB Dragonator body

Having brought back a little of the 2000’s look to 1:10 offroad buggy racing with the release of the Dragonator body shell, JConcepts has added a variant for the latest Schumacher Cat PB 1:10 4WD Buggy. The new body is heavily inspired by the early 2000’s dynamo. With the 1:10 buggy class is ruled primary by JConcepts performance bodies such as the S2, F2, P2, and S15, for the new season of offroad racing Jason Ruona and his Florida company got a bit more creative and sculpted this angular shell stating the ‘Cab forward, cab rearward, the debate lives on, but the Dragonator is something different’. A good portion of the new shell is all cab, the narrow front develops width as it reaches the rear, up to a specialty fin where it picks up stability. The long swooping side windows provide an aggressive stance that all converges to the front like an arrow. The power pods are raised in advanced territory directing and channeling flow over the centre of the chassis and through to the rear. The heavy inner edge of the power pods is a hard stop but ultimately the defining concept of the new item. The decreasing radius portion of the back of the cab is unique, created to ride low-profile on the track surface and equalise the front to rear bias of the all-cab concept. Stepped rear “doghouse” serves as the termination point of the windows and positions it just before the rear tower. The body arrives as clear polycarbonate with protective film and is available in standard formed thickness.

JConcepts Silent Rage, Kosmos, Frizzy, and X-Bite 1:10 Buggy Tyres

JConcepts is wrapping up the final full week of June with a big drop of new tyres for 1:10 Buggy releasing the Silent Rage, Kosmos, Frizzy, and X-Bite. The Silent Rage was originally designed for the 2023 IFMAR World Championships at Hobby Action Raceway in Arizona. During the build-up to the world championships, the team felt the open front tire could leave an option to create an advantage for its team drivers and the new tire was specifically designed to have 2 different sidewall heights and depending on conditions, the user could alter the direction for gains. As it happened, the indoor circuit did not mature as rapidly as thought and the new Silent Rage were never removed from hiding. This did not stop the development, JConcepts doubled down and created a rear tire in the same fashion. Throughout 2024-2026 the team has tested this concept at tracks across the country with great results on off-road and dirt oval track competition. The composition of the tyre body makes it ideal for high-bite surfaces. A racer can place the low-profile sidewall toward the inside or outside depending on conditions or stagger for dirt oval or banked conditions.
