🔥 Twisted™ 700R4 Pro™ Overdrive Conversion Package

💪 Rated 500–550 HP

Stronger. Faster. Built for Real Street Power.

The Twisted™ 700R4 Pro™ Overdrive Conversion Package is engineered for serious street and street/strip vehicles producing 500–550 horsepower.

A major step above our Street™ build, the Pro™ delivers increased clutch capacity, stronger hard parts and improved hydraulic control while maintaining dependable overdrive performance and street-friendly operation.

Ideal for high-output small-blocks, 383 strokers, LS swaps and aggressive street combinations that need increased strength without moving into a full race transmission.
