Bert LMZ Transmission Kit for 1 Piece Rear Main Seal

Where the standalone LMZ ships bare, this version packages that same hydraulic-clutch 2-speed gearbox together with a steel bellhousing and a drive flange, sized for 1986-and-newer Chevy V8s running a 1-piece rear main seal. A 2.40:1 low gear is published for this kit, a figure not listed on the bare transmission.

What carries over from the LMZ design

The internal hydraulic clutch and dog-tooth gear set remain the core of this package, giving the same quick, positive shifts and direct-drive high gear found on the standalone unit, while the compact case still comes in roughly 2-5/8 inches under Muncie length. At roughly 40 lbs, it suits IMCA, WISSOTA, Late Model, Hobby Stock, and Street Stock builds that want a lightweight, clutch-equipped gearbox.

What's boxed with the transmission

Along with the steel bellhousing and matching drive flange, this kit adds a braided hydraulic clutch line with its AN adapter fittings, a bellhousing bolt kit, and a bottle of racing transmission fluid. A shifter and slip yoke aren't part of the package, so plan on a standard two-lever shifter and a compatible driveshaft from elsewhere.

Common questions

Does this include the bellhousing the bare LMZ lacks? Yes, this kit adds a steel bellhousing sized for the 1-piece seal.

Is a shifter included? No, a standard two-lever shifter is a separate purchase.

This kit carries Bert's 1-year limited warranty against defects in materials and workmanship for units installed and raced normally.
