New Style Flywheel Steel Gilmore

The BERT TRANSMISSIONS New Style Flywheel Steel Gilmore (part number 370-S-G-BOD-Kit, SKU BER370-S-G) is a high-strength, two-piece steel flywheel engineered for serious small-block Chevy V8 builds. Designed as a complete kit with internal balancing and featuring a Gilmer pulley configuration, this flywheel delivers the precision and durability demanded by performance enthusiasts and transmission builders working on street applications, drag racing platforms, and engine-swap projects where reliability and proper rotating assembly dynamics are non-negotiable.

The two-piece design of this Bert flywheel separates the inertia ring from the core body, allowing for optimized weight distribution and superior heat management under sustained high-rpm operation. Internal balancing means the assembly arrives pre-matched to your engine's specifications, eliminating the guesswork and secondary balancing costs. The Gilmer pulley mounting system provides clean accessory drive compatibility and maintains the factory-appearance belt routing geometry. At 5.8 lbs, this is a precision component built to OEM tolerances and designed for long-term durability in high-output small-block applications.

This flywheel is ideal for Chevy V8 engine builders, transmission shops, and experienced DIY builders handling complete engine builds or rebuilds. Whether you're assembling a crate engine, rebuilding a factory small-block with modern performance parts, or executing an engine swap into a classic platform, the BERT transmission-grade flywheel ensures your rotating assembly meets the demands of consistent, trouble-free operation. The kit format means all necessary components arrive together, streamlining installation and reducing the risk of compatibility issues.

BERT Transmissions is recognized in the transmission and engine-building community for producing components that support high-performance rotating assemblies. A steel Gilmore-style flywheel with internal balancing and two-piece construction represents the performance standard for builders who prioritize precision engineering over budget alternatives, ensuring your Chevy V8 platform has a foundation capable of handling sustained power delivery without compromise.
