8L90 4x4 Conversion Kit

Stop hunting for a rare 4x4 transmission. The Wicked Wrench Motorsports 8L90 4WD Conversion Kit transforms a plentiful 2WD 8L90 into a high-performance 4x4 8L90E layout — perfect for Gen V LT restomods, classic Chevy K10 builds, and custom off-road rigs.

By converting the output shaft away from a 2WD slip yoke configuration, you can easily adapt your drivetrain to standard 4x4 transfer cases. Retain the massive 7.0 overall gear ratio and lightning-fast shift speeds of GM's modern 8-speed automatic platform without the multi-thousand dollar crate transmission price tag.

What's Included:

• Complete brand-new 4WD rear housing with pre-pressed bearings and heavy-duty oil seals
• Premium 4WD output shaft engineered for a leak-free, factory-quality fitment
