It is with great pride that we're able to make 2019 the year that we introduce our gearboxes to a brand new range of classic cars. Owing to the success of our MX-5 derived gearboxes for use in MG and Morgan Motor Company vehicles, we have been able to expand our reach, to cover the TR8 and the TR7 V8.

Can I fit the kit myself? 

In short, yes. If you are confident removing and installing a standard Triumph gearbox will have no trouble fitting one of our kits. Everything has been specifically designed to match your vehicle, so there is no need to bodge anything - it will all sit just so.  

If, however, your mechanical skill stops short of gearbox installation, we’ve got you covered. We can deliver your new gearbox straight to your chosen mechanic and speak directly to him (or her), should they have any questions regarding the install. 

We also offer a Triumph gearbox installation service from our facility in Leicestershire - the ideal choice if you are UK-based. 

 

Gearbox reviews and features

With our TR gearboxes being entirely new, as yet we have not had any kits available for media tests. In lieu of specific reviews, we think it worthwhile to share reviews of our very well-received MG gearboxes: 

MG Enthusiast feature

MGCC feature

 

Shed some lbs: 

The all-alloy casing of our gearbox means significant weight savings can be achieved with this kit - up to 23kg compared to the R380!

 

The perfect ratio: 

The gear ratios of our MX-5 gearbox work perfectly in the TR7 V8 & TR8, utilising the extra torque delivery of the V8 brilliantly.

 

Gear Ratio - Mazda Transmission 
1 3.136
2 1.888
3 1.330
4 1.000
5 0.814
