DESCRIPTION:
What we offer in this transmission is the best of the best in terms of functionality, Strength and Durability. Specifically built for racing applications, allowing high torque and bhp throughout the drive set with substantially reduced fatigue resistance.
Quicker shifting is now possible along with 20 to 30% gain in strength due to Shot peening and REM Isotropic Super Finishing of the hubs, sleeves, shift rails and shift assembly, along with adding cooler running temps. All Synchronisation bulk rings are replaced with custom modified carbon fibre upgrades to give that extra bite at high rpm shifts / gear changes increasing Durability. The output shaft is replaced with a stronger Brena Corsa solid shaft. A prone weak point within the EVO transmission which destroys the transfer box when failure occurs.
The next step is to make the reservoir plate removable, the reason is to make the oil chamber serviceable, we add security torque bolts to secure the plate in place. We can now service the chamber’s this is a great for end of session servicing.
Now we add a Neodymium Magnet these free energy magnets are very strong and will be sure to stop any unwanted contaminants entering the vital components. This is just one of many modifications we offer to make sure that you are getting the absolute best in terms of results and performance. So you can feel assured that you are getting the most comprehensive gearbox available.
We have many options in respect to modifications, up rated/improved parts, and processes such as gear detailing and synchro matching.
The whole drive mesh is blue printed to confirm the correct mesh and tolerances for the best possible touch. Modified bearings are used throughout the build to cope with the added stress and load on the components along with new hardened steel thrust washers.
Custom fabricated shims are ground in house to our own specific tolerances, this adds a large benefit when high thrust is loaded on to each bearing, letting us make micron adjustments so to avoid any premature failure.
This specific gearbox comes with a High load top bearing, internal conduit oil canal and oil gantry modification. This allows a more reliable, efficient and constant supply of oil to key area’s within the transmission. The higher load bearing allows a higher thrust and torque load to be added to the Drivetrain.
A modification can now be made to the dreaded input shaft bearing! replacing it with a tapper bearing giving a tighter preload reducing deflection making the gears and input shaft stronger allowing more power to be sustained.
Input shaft failure is common on high torque Evo transmissions mainly we see fatigue on either the clutch radial splines or the 5th driven gear. With this in mind an alternative shaft is used along with added attention to detail when shot peening these areas, 3rd and 4th gear also under go the same treatment.
Modifications are made to the oiling system of the box to allow increased oil flow to the critical components along with a case modification to allow more oil to dump into the sump.
Upgrade to the 1st gear needle bearing is also added due to the high radial forces causing the gear to fail under heavy loads such as launches.
Hi Spec components used throughout offering the most enhanced build possible to make the transmission that lasts race after race.
We have now produced many Stage 3 boxes all in vehicles running from 550 ft lbs to 800 ft lbs torque.
So you can feel assured that you are getting the most comprehensive gearbox available

WORKMANSHIP:
The workmanship and attention to detail that goes into one of our gearbox builds is bar non you will not find any corners cut here. We pride our selves on our gearbox builds not only internal but external and guarantee our boxes.
All gearboxes are built by hand in house, every part is scrutinized and inspected and nothing is left to chance. My gearboxes are fully reconditioned units which means all serviceable parts are replaced. I find my self more and more repairing gearboxes that have apparently been reconditioned months prior to find out that all that may have been changed is the absolute minimum or nothing at all.
All preload shims custom ground in house to a 1 micron tolerance. Gear contact mesh checked throughout with gear detailing available upon request.
A properly rebuilt automotive part.
Rebuild includes full strip and cleaning of internal oiling system, with modifications to increase oil flow.
The item has been completely disassembled, cleaned and examined for wear and breakage. Worn out, missing or non-functioning components have been replaced with new or rebuilt components. It is the functional equivalent of a new part and is virtually indistinguishable from a new part.
WARRANTY:
We’ll also guarantee our work for 1 years, or 12,000 miles (whichever comes first) on fitted gearbox, 6 months / 6,000 miles on ‘take-away’ units and 3 months for all auxiliary parts.
SHIPPING / LOGISTICS:
The gearbox will be shipped directly to you on a half pallet, please observe how the gearbox is secured and fastened to the pallet. This will help you when it’s time to return your old gearbox.
Shipping price advertised is for a one way shipping to your desired destination, and does not include the Collection of your old gearbox. This can be arranged at an extra cost.
UK Mainland Shipping is covered.
Scottish Highlands and Northern Ireland post codes available at an additional cost.
SURCHARGE:
The surcharge is additional to the purchase price, therefore it is required before the gearbox is shipped. The surcharge amount is £550 and maybe refundable once you’re old gearbox is received.
The old gearbox needs to be unmolested and serviceable, what this means is that the gearbox needs to come complete not stripped or dismantled, and must have no holes or damage to the case.
If your gearbox is leaking oil from the case or has no drive, then its safe to say that the gearbox is most likely non serviceable. In this case the £550 surcharge will not be refundable.
EXCHANGE PROCESS:
All Gearboxes are sold on a exchange basis, therefore your old gearbox is required, the exchange process is designed in away to make it convenient for the buyer. Once the new gearbox has been received simply refrain all packaging and securing fixings, these will assist you when returning the old gearbox . The return of the old gearbox is at a cost of the buyer, it is the responsibility of the buyer to return the gearbox in a safe and secure method with the packaging provided.
(The exchange process can be handled by us for an additional cost, usually the same price as the shipping to you.)
DEPARTURE:
All Gearboxes are bespoke and built to order, there for there can be down time before the gearbox is shipped. We aim to get most gearbox shipped within 3 days of the purchase date.
(This can be extended considerably if the gearbox is a bespoke item and requires a build slot.)
OPENING HOURS:
Our workshop hours are 9.00am – 5.00pm Monday – Friday and 9.00am – 1pm Saturday.
