Pro-Shift Bump & Blip Shifter II TM

Available for Sequential gearboxes                                                                                                                                                                                                                                                                                                         Specifically designed to provide super fast clutchless up & downshifting this unique system provides clutchless "flat" upshifting with intergrated ignition or fuel injection ramping restore facility allied with ultra-high speed Auto-Blipped downshifts.


Uniquely utilising a two way Hall Effect Sensor to trigger the "Bump & Blip II'" GCU (Gearshift Control Unit) this revolutionary operation method provides far faster more accurate gearshifts than other conventional methods without the need for load cells.

Important note, The Bump & Blip II's two way Hall Effect Sensor has two 6mm male threaded ends and requires fitting "in line" to the gearbox's operating rod or gearlinkage so the gearshifting forces act on the cell to effect upshift cuts and downshift blips, if your vehicle does not have this then Pro-Shift can provide alternative solutions.

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

Timer controlled ignition or fuel injection ramping facility giving smooth power restoration after "flat" upshifting, ideal for use in wet or slippery conditions.

Fully adjustable timer controlled DBS ™ (Downshift Blipping System) "on times" providing ultimate control over clutchless downshifts.

Patent Pending Hybrid Remote cable Downshift-Blipper for Car Throttle Bodies including idle screw replacement ferrule, this works in a pushing motion making the installation very quick and simple, This ultra fast acting downshift blipper utilizing a specifically designed lightweight solenoid will provide reliable high speed clutchless dowsnshifts with a typical "on time" of around 50mS allowing precise multiple downshifts.

Telescopic Throttle Blipper this works in a pulling motion and is suited to throttles where a pushing blipper is not.

DBS ™ (Downshift Blipper System) modules available for Drive By Wire (DBW) throttles

Throttle opening percentage, opening time and trigger points fully adjustable.

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!

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!

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

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. 

TOM ELLIS (UK) May 10 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
