Re-builds

Our gearboxes are known to last 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 re-build from us includes the following:

  • Taking your box apart and inspecting all parts.

  • Once your parts pass inspection we move onto cleaning them.

  • The case is bead blasted and washed, shafts get polished, and the gears get scrubbed down.

  • Next we put new bearings and seals in your cleaned case, then reassemble your case. 

  • We pressure test the new seals to make sure there are no leaks.

  • Then we install the adapters and drive plate.

  • Your gearbox is boxed up and shipped back.

Standard rebuilds start at $1195. If any parts are damaged beyond repair we will notify you of what is damaged and the cost to fix it before moving forward re-building your gearbox. A one (1) year warranty is included on all rebuilds, as well as our limited lifetime guarantee against manufacturer defects.

To order a rebuild please contact one of our Dealers or contact us directly

Repairs

Leaky seal(s), damaged drive plate, stripped thread(s)? No problem we can help. 

To replace a seal we charge $200 per seal, output or input same price.

If your drive plate is cracked or damaged we can replace/fix depending on condition

Stripped the threads in your Soft Or Hard Drive hub? We can either drill and tap, or replace the hub. Input Drive Hub replacements are $150 installed, Propeller Hub Replacements are $225 installed.

Shipping to/from our shop is on the owner of the gearbox, if you don't want to ship you are welcome to bring the gearbox directly to us. Most repairs take no more than an hour. 

Shop visits/drop offs by appointment only, please call ahead.

Flywheels

Stinger Drives Inc. recommends running a JW Performance Flywheel on all of our gearboxes (besides Cadillac's due to clearance issues). "The Wheel" precision-machined flywheels are manufactured using .188" chrome moly steel and feature double-welded replaceable ring gears and the best steel centers. 

 

"Flex-plates" are known to crack and if the crack goes unnoticed it can lead to the flex-plate breaking, causing damage to the gearbox and/or engine. Protect your investment with a JW Performance Flywheel. 

 

Please call or email us to order your JW Performance Flywheel.

Propellers

Stinger Drives Inc. is an authorized dealer of Sensenich and Whirlwind propellers. If you're looking for your next propeller, then look no further. 

 

For propeller pricing please contact us by phone or email.

Soft Drive Plate Installation

If your gearbox has a Hard Drive and you would like to replace it with a Soft Drive 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. 

Soft Drive Kit available for purchase here

We offer this service to ensure our customers get the right parts and the right service the first time. Swapping the drive plates and adapters sounds easy in theory, but trust us when we say its harder than it looks.
