Starter/Flexplate Combo Kit (TS400 & FP300)

The MEZIERE Starter and Flexplate Combo Kit (TS400 & FP300, part number TSF112) pairs a true billet 400 Series starter motor with a precision-engineered 168-tooth flexplate in a single integrated solution designed for Chevy V8 engine installations. This combo approach eliminates the guesswork of sourcing compatible components separately, ensuring proper engagement and reliable cold-start performance from the first turn of the key.

The FP300 flexplate meets SFI 29.2 safety certification and is constructed from steel with internal balance design, a critical specification for high-RPM durability and vibration control in performance and street applications. The 2-piece seal configuration reduces oil weeping at the seal interface, a known failure point in standard single-seal designs. Straight-mount architecture maintains OEM bolt-pattern compatibility while the billet starter construction delivers superior longevity compared to cast alternatives, particularly in vehicles subject to frequent cold-weather starts or modified ignition timing.

This kit serves builders and enthusiasts restoring or upgrading classic and modern Chevy V8 platforms who require components engineered to work together without fitment surprises. Whether preparing a stock rebuild or a performance platform, the combo kit approach reduces assembly risk by removing the compatibility variable. The SFI-certified flexplate is essential for any vehicle running a converter or modified torque capacity beyond stock parameters.

Buyers selecting individual components often encounter bore mismatches or seal-height discrepancies; this pre-matched pair eliminates those concerns. The internal-balance design is particularly relevant for engines with non-stock crankshaft or flywheel modifications, where external balance assumptions break down. At 23.99 lbs shipped, the kit arrives ready to stage for installation without secondary sourcing or compatibility verification.
