Hemi Starter TST406H 10-Pitch

The MEZIERE Hemi Starter TST406H 10-Pitch is a gear reduction starter purpose-built for Mopar V8 engines equipped with 10-pitch flywheels. This True Start 400 Series unit delivers reliable cold-start performance in high-compression and modified applications where factory starters fall short. The adjustable mounting block design accommodates engine bay variations common in restoration and performance builds, eliminating fitment guesswork and reducing installation time.

At 14.32 lbs, the TST406H offers a significant weight advantage over traditional starters while maintaining the torque reserve needed for demanding starts. Gear reduction technology multiplies starter motor output, translating to faster engagement and reduced electrical load on the battery—critical when running higher compression ratios or in cold-weather operation. The compact profile (7.6 x 7.1 x 11 inches) fits tight engine bays without requiring extensive modification. MEZIERE's engineering ensures consistent cranking velocity across repeated start cycles, preventing the slow-crank issues that plague underpowered original equipment in modified Hemis.

This starter targets Hemi engine builders, hot rod enthusiasts, and restoration shops working with 10-pitch flywheel platforms. It solves the specific compatibility gap where modern performance demands exceed factory starter capabilities. Whether upgrading a carbureted classic or integrating forced-induction into a street machine, the TST406H delivers the starting authority expected in serious powerplants. The True Start 400 Series reputation within the performance community reflects proven durability under repeated high-compression starts and consistent field performance across diverse climates and driving conditions.

Gear reduction starters represent an industry-standard solution for applications where factory equipment is marginal. The TST406H's 10-pitch specification ensures exact flywheel compatibility without adapter requirements, while the adjustable mount platform secures installation regardless of minor engine bay variations found in field restorations and custom builds.
