Our Product Line
We offer Hard Drive gearboxes, Soft Drive Gearboxes and Experimental Aircraft gearboxes with 1.54, 1.73, 2.09, 2.38, 2.55, 2.68 and 2.88 ratios.
Currently all new gearboxes are built to order due to the volume of work we have.
The case of the gearbox is cast from 356 T6 heat-treated aluminum. Our large helical cut gears are heat-treated to ensure durability as well. Our careful assembly process sets the gears at zero lash for quiet running.
The gearbox cases can be polished to a chrome like finish for an additional $350.
(May add up to 10 days to the build time).
Our gearboxes are known to last for thousands of hours with proper maintenance, but eventually they do wear out. Send us your gearbox and we'll rebuild it from the ground up. A rebuild from us includes:
Our rebuilds start at $1195. If any part is found to be damaged beyond repair we will notify you before moving forward with the rebuild with the cost of the replacement part.
A one (1) year warranty is included on all rebuilds as well as our Limited Lifetime Warranty against manufactures defects.

Stinger Drives, Inc. recommends running a JW Performance Flywheel on all of our gearboxes. "The Wheel" precision-machined flywheels are manufactured using .188" chrome moly steel and feature double-welded ring gears and high quality steel centers.
"Flex-Plates" are prone to cracking. If the crack goes unnoticed it could cause severe damage to the gearbox and/or engine. Protect your investment with a JW Performance Flywheel.
Please contact us by phone or email to order your JW Performance Flywheel.

Soft Drive Plate Installation
If your gearbox has a Hard Drive plate and you would like to replace it with a Soft Drive plate we would be happy to install it for you. All you need to do is get your gearbox to us, (either drop it off or ship it) and buy the Soft Drive Kit. We will install your new Soft Drive for free!
The Soft Drive Kit is available for purchase here.
We offer this installation service for free to ensure that the drive plate swap is done correctly the first time.
Swapping out the drive plates sounds easy in theory, but trust us, it's harder than it looks to get it right.
