They are incapable of answering regardless of the question that you have about a gearbox for which they received a ~2500 GBP. If you ask: Can I put a revers light switch? The answer is: "We don't know..." Can I put a speedo: "We don't know..." I don't recommend them at all. They are a huge dissapointment.

They could support their products like other manufacturers do no matter how old they are. What am I supposed to do with a sequential gearbox I can no longer get parts for ?? throw it away?? They could also reply to emails and facebook messages... that would be nice. Guess my new gearbox will be from Sadev !

The Quaife ATB fitted to my PG1 gearbox was the best modification to the car. Power is nothing without control, as the saying goes! Recommended.

Been running a six speed sequential in my TD5 Defender 110 for just over a year now, totally transformed my driving and results. We race in the French Tout Terrain Championship which is all hard off-road very rough tracks, the old "Cimes Tractor" spends a fair bit off and on the ground and we find the sequential box is a godsend and works very well… with the tuned TD5 engine. Sadly a little driver error two weeks ago in the mountains at Saint Pee sur Nivelle I managed to loose control and hit a tree very hard in 5th, the Defender sustained heavy damage and the front axle was pushed back

I would not install a quaife gearbox in my tractor,after buying to brand new gearboxes for both to fail & require full rebuilds & then to fail yet again & not forgetting the list of excuses & poor service by quaife,we had gearboxes inspected by an independent to confirm that that internals/gears where different grades of metal & build quality was below poor,we now run a SADEV box quality quaife 101% scrap
