Enhance performance, extend engine life, and reduce vibration
Engine balancing is a critical step in engine assembly that ensures all rotating and reciprocating components work in perfect harmony. With professional balancing, you’ll benefit from smoother operation, improved longevity, and a noticeable increase in overall engine performance.
At JS Auto Tuning, we provide expert engine balancing services focused on precision and performance. Whether you’re fine-tuning a race engine, or maintaining a daily driver, our expert team and advanced equipment ensure your components are perfectly balanced for optimal results.

What we offer
We provide a full suite of in-house balancing services using industry-leading tools and techniques:
Dynamic Crankshaft Balancing
Using our state-of-the-art Turner Balancer, we precisely measure and correct imbalance in your crankshaft to ensure smooth rotation at all RPM ranges. This is essential for both stock and high-performance engines.
Conrod End-to-End Balancing
We balance connecting rods from end to end to equalise mass across all cylinders. This reduces internal stress and improves consistency across combustion cycles.
Piston Balancing and Rocker Assembly Matching
Pistons are weighed and adjusted to exact tolerances to eliminate variations that could affect engine dynamics. Rocker assemblies are also matched in weight to maintain uniform valve operation and reduce mechanical noise.

Who is it for?
Our services are available for all makes and models, including:
- Classic cars
- Modern performance vehicles
- Off-road vehicles
- Racing engines
- Custom builds
Whether you’re an enthusiast, a professional engine builder, or a garage owner, we can support your engine balancing needs with speed, accuracy, and unmatched attention to detail.
