Stand Alone 12 Volt operation with absolutely no requirement for vacuum modules to power the throttle blipper.


Uniquely utilising fully adjustable Proximity sensing "Magic Eyes" to trigger the "Bump & Blip" TM GCU, this revolutionary operation method provides fast and accurate gearshifts without the need for commonly used  load cells

Integral timer controlled adjustable ignition or fuel cutting allowing "flat" upshifting

Ramping facility giving smooth power restoration after "flat" upshifting, ideal for use in wet or slippery conditions

I had a safe journey home as I took things nice & steady with the new Pro-Shift PS3.5 System installed on my Caterham 7... Then I went for a drive last weekend and WOW, the 7 is now so so fast, I've even said scary fast to some!.. Lovin' it!!!

Finally I could try DBS™ at the Mallorca Ciruit and the result was FANTASTIC, the operation was very smooth and precise... I had no problem throughout the day! A couple of friends asked me to try my bike and they were surprised at how well it worked and asked me to install the DBS™ on their Kawasaki ZX10R 2012... Thank you so much for everything!

VG Motorsport Racing with a Rage buggy using Pro-Shift System, managed to finish the Rally-Greece off-road 2017 edition - 7th overall, 3rd in class, 1st Greek Team out of 34 Competitors!

Thank you all !!!!

The new B&B II with strain gauge is FANTASTIC!.. An Awesome race weekend, I rode it and found it to work flawlessly. The ability to micro adjust just turns it into night and day. It was easy and worked perfectly... I was impressed!


I'm driving a kart with a Vortex 125ccm RKZ engine and in the past used another shifting system but it wasn't reliable and not powerful enough... I found the Pro-Shift PSU system with the stronger solenoid. The first test ride was great, a huge difference between old shifter and Pro-Shift! Shifts were 100% precise and super-fast, I had more than 300 rounds on our circuit without any problems!

MICHAEL STEINER (Switzerland) May 14 2017

After 3 seasons of use the gearbox internally looks like new and needs no revision at all. This shows how good the Pro-Shift system has worked. All I can say is thank you very much to all at Pro-Shift for such a good package, I can fully recommend it to anyone looking for a similar system!

MIKE CASON (UK) November 2 2014

Thanks so much Pro-Shift! The system is amazing on the road, can't wait to get it on the track. Well worth the money, the only thing that beats your product is your customer service. Couldn't recommend enough!!!

ROBERT GUY (UK) August 10 2016

Many thanks to Roy and Chris, amazing service as always! You are a fantastic team up there and always willing at short notice to help.

ADRIAN LEWIS (UK) May 24 2016

Everything installed and if I had to give a rank from 0 to 10 for it I would give 12.

LUIS HENRIQUE A. MONTEIRO (Brazil) February 14 2016

Really happy with the system. It's just completed the bike, it's made it so stable on heavy braking and down shift!! The lap times are the proof I needed! Transformed the bike so a big thank you to all at Pro-Shift.
