Following the massive success and rave reviews of our standard 6-Speed Transmission for the Small Block V8-440, the dedicated version for the upcoming CISON LS-52 V8 is officially on the way!
Due to high demand from our community, the Stirlingkit engineering team is currently pushing hard on the R&D for this premium upgrade. The project is expected to officially launch in July 2026, and you can now sign up to secure your spot for early pre-orders.
Please note: Because the finalized industrial design is still being optimized for perfect LS-52 block integration, the product image currently features a black silhouette to represent the development phase. The final production design is subject to change and may vary from the reference prototype image, which is provided for conceptual reference only.
NOT Directly Compatible:
Please note that the existing standard 6-speed transmission designed for the Small Block V8-440 is temporarily NOT compatible with the new CISON LS-52 V8 engine.
Future Upgrade Solution:
For our loyal customers who already own the V8-440 transmission, our R&D team is currently testing a custom-designed flywheel housing (bellhousing). We are evaluating whether this separate adapter can bridge the compatibility in the future. Stay tuned for testing updates!
This custom 6-speed transmission is not a mass-produced factory item. To ensure the absolute highest level of mechanical precision and flawless gear engagement, every single unit is 100% meticulously handcrafted and hand-assembled by our master technicians.
Because of this rigorous, time-consuming artisanal process, production is slow, and the total availability for the first batch will be strictly limited. Joining the waitlist is the only way to ensure you don't miss out.
This is a precision scale model engine transmission designed solely for hobbyist mechanics, custom RC builds, and desktop engineering displays.
Design Optimization Notice:
As our engineering team continuously fine-tunes the gear ratios, structural tolerances, and housing aesthetics, the final delivered product may feature visual or structural adjustments compared to our early concept/prototype images. All images and descriptions are for illustration purposes only.
Model Scale Limitations:
It is engineered to simulate realistic gear shifting (6-speed + high/low range) and provide mechanical realism for the CISON LS-52 V8 model.
No Real-Vehicle Comparison:
The performance, torque handling, and internal tolerances of this scale model kit cannot be directly compared to real, full-sized automotive transmissions. It is built for miniature mechanical beauty, not real-world automotive stress.
V8-440 Legacy:
Built on the proven architecture of our highly praised V8-440 6-speed gearbox, but redesigned specifically to handle the output and mounting layout of the new LS-52 block.
Hand-Assembled Precision:
Each gear, bearing, and shifting fork is individually calibrated by hand for smooth, satisfying tactical feedback.
Premium Multi-Axis CNC Machining:
Crafted from high-grade metal alloys to match the high-end industrial aesthetics of your CISON LS-52 V8.
Secure Your First-Batch Priority:
Since these transmissions are slow-built by hand, the first batch will sell out fast. Waitlist members will receive private pre-order links before the public release.
Launch & Engineering Alerts:
Receive behind-the-scenes R&D sneak peeks, prototyping footage, and an instant notification the exact moment orders go live in July.
