LS1 CONVERSION FLEXPLATE 6 BOLT SUITS TH350 TH400 TRANS

Description

Achieve flawless power transfer between your LS1 engine and classic TH350 or TH400 automatic transmissions with this specialized conversion flexplate. Designed to address the challenge of mismatched bolt patterns and fitment issues, it provides a direct, secure connection that maintains drivetrain integrity and reduces installation complexity.

This flexplate features a 6-bolt pattern specifically tailored to match the LS1 crankshaft and TH350/TH400 transmission bellhousing. The 42.5 cm diameter ensures proper alignment and engagement with the torque converter, eliminating common vibration and wear problems associated with incompatible flexplates.

Constructed with high-grade materials, this flexplate weighs 4.23 kg, balancing durability and rotational stability. Its robust design withstands the high torque and RPM fluctuations typical in performance and street applications, ensuring longevity and consistent operation under demanding conditions.

The compact 2.5 cm thickness contributes to reduced flex and enhanced structural rigidity, which translates to smoother power delivery and minimized stress on transmission components. Dimensions of 42.5 cm width and height confirm compatibility with standard TH350 and TH400 transmission housings, simplifying installation without the need for modifications.

Trusted brand TCI applies precision manufacturing standards, guaranteeing exact bolt hole positioning and surface flatness. This attention to detail prevents misalignment that can cause premature wear or transmission failure, safeguarding your investment and vehicle reliability.

Designed exclusively for LS1 engine swaps into GM transmissions TH350 and TH400, this flexplate addresses the critical need for a conversion component that maintains OEM-level performance and fitment. It replaces generic or universal flexplates that often fail to deliver proper engagement and durability.

In summary, this 6-bolt LS1 conversion flexplate combines precise dimensions, robust construction, and application-specific design to ensure seamless drivetrain integration. It delivers tangible benefits in installation ease, operational reliability, and long-term durability, making it an essential component for LS1 engine transmission conversions.
