Bert Gen 2 Std Length Transmission Kit for 2 Piece Rear Main Seal

WISSOTA has approved this standard-length Gen II gearbox for Midwest Modified competition, and a bottom inspection opening built into the bellhousing flange makes servicing easier than on a sealed design. Fitment covers small block Chevy and Ford engines built around a 2-piece rear main seal, and the torque figure holds at 600 lb-ft, shared across Bert's Gen II range.

How the high gear design helps

Once shifted into its 1.00:1 high gear, first and reverse gear sets disengage fully rather than continuing to spin, which cuts rotating mass and sharpens throttle response compared with a gearbox that keeps every gear turning. The aluminum case keeps overall weight down for circle track, dirt modified, and limited-engine classes.

What ships, and one thing to confirm

A steel bellhousing with its hardware and the installation components needed to mount it ship with this kit; the shifter is a separate linkage-operated unit rather than something boxed in here, and a slip yoke is likewise sourced on its own. The listing also calls out a hydraulic clutch line among the included parts, which doesn't match a linkage-shifted design, so confirm your clutch setup with us before ordering rather than assuming either spec.

Common questions

Is this SFI certified? No, it's listed as non-SFI rated.

Is a slip yoke included? No, that part is left for the buyer to source.

Normal racing use is what the 1-year limited warranty on materials and workmanship assumes.
