Neat Gearboxes Neat Gearboxes makes drivetrains stronger and more efficient. Neat Gearboxes provides powerful solutions to strengthen your standard manual gearbox.

Our objective is to assist you to get all of the potential out of your car or bike, whether it be for rugged off-road use, a finely balanced race setup or something in between. We go beyond “bolt-on”, and implement the best possible technologies in-house to modify your gearbox to be able to cope with increases in power, load and torque, while keeping it inherently usable, just as the factory inten

ded. Neat Gearboxes' services include shot peening to SAE standards, Isotropic Super-Finishing (ISF), magnetic particle inspection, synchroniser blueprinting, lubrication and cooling improvements, and of course an array of cleaning methods all performed in-house. Our core products include the "Peen and Polish" package, where you send your standard gear set to us; we hot tank, inspect, crack test, shot peen and isotropic super-finish (ISF) your gear set and associated components (see the website for full details), package it up and ship it out. Shipping is free Australia wide and our turnaround on this service is 3 business days, as long as you book. "Peen and Polish" prices start from $600 and go to $900 depending on the number of components. Of course we are more than capable of reconditioning your standard gearbox back to factory specifications, too. We stock a range of hard to source parts for many performance and classic gearboxes, including bearing kits, synchronisers, seals and various gears. We also hold a selection of carefully chosen oils and fluids for your gearbox, differential, transfer case and even engine.

Sneak peak of our long awaited SportSync project for the w5m33 transmission, found in evo 1-3, galant vr4, DSM and other awd 4g powered 90s heroes.

The factory gearboxes, frankly, suck. If the centre diff doesn't nuke itself, 4th gear will.

We have redesigned from the ground up. Our kit includes synchros, hubs, sleeves, billet bearing housing, wider helical gears made of 9310, and a complete centre diff unit that is entirely re-imagined.

While still in the prototype phase, we are getting close now. Exciting times.

Here's a demonstration of how well our c-clip mod works for the AZ6.

While not ideal, this BRZ broke the teeth off of 4th gear before popping the clip.

The countershaft and c clips were actually fine to be re-used despite the catastrophic failure.

We are presently in the phase of moving workshops. Not closing down or anything, just moving premises and want to refresh the shop.

I have a massive range of used gearbox spares in various states of repair from most popular models that I don't want to take with me.

I haven’t kept anything obviously damaged, so most stuff should be in usable condition - good for rebuilding.

We also have some complete sets of gearboxes (been disassembled/partially disassembled). Models include: Honda - S2000 gearbox, B series cable and hydraulic, k series including AWD

Mitsubishi Evo - 1-3 diff and transfer cases ; 4-6 transfer cases and AYC diffs ; 7-9 transfer cases and SAYC and RS diffs ; Evo X 5-speed gearbox ; GTA Auto

Nissan Silvia 6-speed AZ6

Mazda MX5 AZ6

Ford Ranger MT82 and transfer case

Toyota Landcruiser H series gearbox and transfer case

D40 Navara 6-speed and transfer case
_____
Significant spare parts piles for Skyline 5-speed, GTR Transfer case and GR6 (GT-R); Silvia 5 speed and 6 speed ; Toyota R154 and some W55 W58, C50 and C60 ; Honda B, K and S2000, and of course Mitsubishi Evo drivetrains. Even some old Aussie 4-speed stuff.

I am ready to sell much of this stuff for far cheaper than you will ever find again - hopefully in lots or whatever rather than individual widgets. Basically if you need something that I've mentioned, get in touch via PM and I'll do my best to answer.

This will only be available until the end of the week - Friday 24th of April - whatever doesn't go gets stored or binned. I'm not a wrecker and don't plan on ever doing this again, haha.
