If you race a Schumacher CAT PB, the aftermarket support just got a whole lot more interesting. The British brand has released two performance-focused upgrades in quick succession: a redesigned AEROX bodyshell and a new titanium chassis that promises added stiffness and predictability. Whether you are chasing tenths at your local club or prepping for a national, there is fresh hardware to bolt on.

Aerox Returns, Refined for the CAT PB

The AEROX bodyshell is a familiar name in Schumacher circles, but this version has been modernised specifically for the CAT PB platform. According to the team, the low-profile shell lowers the car’s centre of gravity and boosts stability through high-speed corners — exactly the kind of tweak that pays off on fast, sweeping tracks. The shell is described as “much loved” and it now returns for the CAT PB, having been updated to fit this particular model.

It is not just a concept, either. The shell was used by Ben Smith to win the latest BRCA National at RHR, which gives it solid real-world credentials right out of the gate. Smith’s win demonstrates the body’s effectiveness in competitive conditions.

Buyers get a choice of two thicknesses:

• Standard (0.75mm) – £24.99 (part #AX132)
• Lightweight (0.5mm) – £25.99 (part #AX133)

Both are supplied clear and include window masks, so you can finish them in your own livery. No paint, no decals — just the raw shell ready for your airbrush.

Titanium Chassis Adds 20 Grams, Promises Consistency

Hot on the heels of the body launch, Schumacher announced a titanium chassis for the CAT PB that takes a different approach to performance. Instead of reducing weight, it adds a bit — 20 grams more than the standard kit alloy chassis — but the payoff is a significantly stiffer platform.

The team reports that this stiffness translates into a smoother, more predictable feel over a run. The key words here are consistency and confidence: the chassis is said to provide a controlled front-end feel that works in all conditions. According to the company, the titanium chassis gives your CAT PB “a smoother, more predictable feeling buggy” and “adds consistency and confidence over a run.” The controlled front-end feel provides comfort regardless of track conditions.

Priced at £79.99 (part #U9574), it is a premium upgrade for racers who want a car that stays planted and predictable through long mains. The chassis weighs 20 grams more than the kit alloy version, but the added stiffness is intended to improve handling consistency.

Two Paths to a Faster CAT PB

Together, these releases give CAT PB owners the option to tackle handling from opposite ends. The AEROX body addresses aerodynamics and centre of gravity, while the titanium chassis attacks flex and chassis response. Neither is a full car replacement — they are targeted upgrades that fit the existing platform. Both parts are designed specifically for the CAT PB and can be used separately or in combination to fine-tune the car’s performance.

The AEROX body has already proven its mettle with a BRCA National win, while the titanium chassis builds on the platform’s potential by increasing stiffness and consistency. For CAT PB owners, these are drop-in options that address different aspects of handling without requiring major modifications.

Both parts are available now through Racing-Cars.com, Schumacher’s direct retail channel. Whether you prioritize high-speed cornering stability or a more predictable chassis feel, Schumacher has provided factory-backed upgrades that let you tailor your CAT PB to your driving style and track conditions.

Two RC hop-up manufacturers have released new aluminum steering bellcrank upgrades that replace stock parts with stronger, CNC-machined designs for better steering response. SWORKz has unveiled an aluminum plate for its S35-4/e EVO and T2/e EVO series, while JConcepts launched a Gen2 assembly for the classic RC10 family.

SWORKz Samurai Black Bellcrank Plate

SWORKz’s new option part, numbered SWC-338133, is a CNC-machined aluminum plate finished in Samurai Black with diamond-pattern machining. The company states that the plate provides more solid reinforcement during hard crashes and creates a smoother steering response. It is designed for both the S35-4/e EVO and T2/e EVO series vehicles. The diamond-cut detailing gives the component a high-quality appearance. SWORKz describes it as a new quality option for 2026. Interested buyers can find the plate directly via the SWORKz website.

JConcepts Gen2 Bellcrank Assembly

JConcepts has introduced a Gen2 aluminum steering bellcrank set for the RC10 and RC10 Factory Team cars. The design moves the driving bellcrank to a one-piece solid construction and gives the idler bellcrank a beefy symmetrical form, with the goal of increasing steering response and feel. The parts are CNC-machined and available in blue or black anodizing, featuring silver chamfered edges and a laser-etched JC logo.

The bellcranks are supported by heavy-duty flanged bearings and include threaded standoffs. The kit comes with 8/32 x 5/16” titanium FHCS screws and 5.5 x 4mm titanium ball-studs. An aluminum washer secures the top end with 4-40 x 5/16” FHCS screws. JConcepts recommends applying a light amount of thread-locking compound on all fasteners during assembly. The set also includes CNC-machined steering standoffs and a retaining washer.

Compatibility and Required Parts

The steering kit fits all traditional RC10 models, but requires updating to 5.5mm ball-studs and Team Associated #6535 ball-cups for complete assembly. The ball-cups are available separately. The kit also requires 3.5mm turnbuckles, which are not included. JConcepts notes that the design was optimized around modern racing conditions, using components better suited to durability and track performance.

Design and Testing

Spencer Rivkin, Jason Ruona, and Paul Wynn tested and debuted the new steering system during the JConcepts ONS series round 1 in Savannah, Florida, during the 2026 racing season. The team collected several victories and podium finishes while repeatedly testing the durability of the steering design. JConcepts states that its team builds, tests, and travels the world to support the brand, gathering driver feedback to refine appearance and performance. The product is designed and formed in the U.S.A. and is backed by JConcepts customer service.

Pricing and Availability

The JConcepts Gen2 assembly is offered in two part numbers: #5325-1 (blue anodized, UPC 845937040305) and #5325-2 (black anodized, UPC 845937040312). The retail price for either color is $40.00, with a MAP price of $34.00. The SWORKz bellcrank plate is available through SWORKz.com. For owners of the SWORKz S35-4/e EVO, T2/e EVO, or RC10 series buggies, these aluminum steering upgrades offer a direct bolt-on path to sharper steering feel and increased durability on the track.
