WORLD CLASS SHIFTERS
Pro-Sim is renowned for it's leading the way across the globe for it's Simulator Shifters. Through a partnership with Quaiffe Engineering and Pro-Sim the infamous shifters were born. With the wealth of experience from Quaiffe Engineering and the success that Director of Pro-Sim, Adrian Quaiffe-Hobbs has enjoyed within Motorsports creates the perfect combination to produce the worlds leading shifters.
The feeling is exactly the same as the real car and when you change gear and you can also see the selector rods engaging behind the Perspex cover exactly like your real gearbox would. The design and concept is taken directly from a production Quaife H pattern gearbox.
On our shifter the feeling comes from the selector rods and the centralization device used on most gearboxes rather than relying on a gate plate at the top which is what all other shifters on the market currently do.
The shifter itself is fully adjustable with the force of both centering and going through the gate easily adjustable by the user. The pivot point of the gear lever is also adjustable meaning without changing the length of the lever you can adjust the through between gears.

Following on from the success of our version 1 sequential shifter we have upgraded the design based on feedback.
The new design features a gear lever that is easier to adjust and to many more positions. The new design of shifter is quieter than our version 1 and also more robust, we have also added an adjustable plunger now so that you can chose the exact strength of gear change required.
The main advancement on this version is the optional active shifting that uses a hydraulic system and software to only allow gear shifts when the gear is unloaded exactly like on a real car.
SHIFT LOCK MECHENISM
Up to now there has never been a way to simulate missed gears, nor interact with the software. Pro-Sim has created a worlds first Simulator Shift Lock Mechinism designed to work on both Sequential & H Pattern Shifters!

SHIFT LOCK EXPLAINED
A synchromesh gearbox is what you would commonly find in your road car. This type of gear is engaged using cones to match the speed of the gears and then held in place with multiple ‘teeth’.
With this type of gearbox there is virtually no play when in gear but there is a lot of surface area with load on holding the gear in place. Because of the load on the teeth and the fact there is not much space the gear needs to be doing almost exactly the same speeds to be able to engage and this is what the cones do but they cannot overcome the engine brake without doing damage to the gearbox and so the clutch is needed for all changes.
A dog engagement box is what you will commonly find in race cars and on most sequential gearboxes. This type of gear usually has 3 to 6 ‘dogs’ on each gear and there is a lot of free space for them to engage.
When shifting gears because of the space between the gears normally there can be up to a 900rpm difference in gear speeds and the gear will still go in, because of this you do not need the clutch.
To make a gear change you need to reduce the load on the dogs so that it can be released, this is normally done by just lifting the throttle on the up change. To change down a gear there is already a reduction in load that is sufficient you just need to blip the throttle so that you do not lock the rear wheels or cause unnecessary wear on the gearbox.
We are now able to replicate both types of shifting accurately; more importantly for dog engagement you are able to pull the lever very hard when accelerating and you will not be able to change gears but as soon as you lift it will go in.
This was very important for us because is most race situations a gear change in a sequential box would happen by preloading the lever first and it was the number 1 priority this was achievable.
Gear changes are done this way to reduce the shift time as you only need to lift until you feel it go in and quite often gear changes will be made with 30% throttle still applied so there is no loss in engine torque.
For the synchromesh option you will not be able to shift gears unless the clutch is pushed, you will however be able to preload the lever prior to pushing the clutch the same as the dog engagement box.
Our solution allows preload because we are using a proper hydraulic system rather than just a cheap solenoid. This is critical because using something like a solenoid means if you apply preload and then activate it you would need to release the force before the solenoid would activate, a problem not encountered with hydraulics.
MOTION RATIO ADJUSTMENT OF H PATTERN
You are able to adjust the motion ratio following our video guide below.
All shifters leave our factory with the bearing in the upper position which gives the shortest travel on the lever. With the bearing in the lower position the same length lever will travel further. The photo below shows the difference you can expect it to make, this photo is without the shaft extension and shows 6th gear engaged.
