Just to add per
@Stefan Mikes mention: I have the Vado SL 4.0 and recently added the RedShift stem. The most similar RedShift stem when compared to your stock/OEM specialized stem for that bike would be the RedShift 80mm 6 degree stem. Like the Specialized stem....this stem can be installed to provide an upward angle or if reversed a downward 6 degree angle.
The installation is dead simple and requires nothing aside from allen wrenches although a torque wrench would be best.
As others mentioned....RedShift offers other stem lengths so this would be an excellent time to consider whether you might like your bars further out or closer....but the 80mm is so very very close to OEM configuration that you are unlikely to notice a difference when compared to your current setup (Specialized installs the stem at the upward angle configuration). At first install I wasn't sure that I was getting much benefit if any from the suspension.....which in hindsight is a good thing....because this stem will not provide so much suspension as to 'distort' the character of the bike or make your handling squishy. After some miles I really do enjoy the RedShift suspension stem and find it to be a worthy addition....in fact my hands no longer become numb after long rides. Just understand that you will not be suddenly astonished at the results from this suspension stem....it is subtle....again a good thing.
Important Note To Consider: Your front headlight mounts to your OEM stem and is handled via a Specialized plastic mount which affixes/slides into a 'notch' which is part of the bottom portion of your OEM metal stem. Once you remove your OEM stem to replace with the RedShift stem you lose the mounting notch and you will need to find an acceptable solution to re-mount your headlamp. I pondered many of these solutions which can be found here at the forum....some more sophisticated than others but few satisfactory to me. I came across a Lezyne (the manufacturer of your headlamp) stem mount part number 1-LED-RP-EMTSTM-V104. Surprisingly this part is not so easily available via retail but I found it here on ebay for $20
https://www.ebay.com/itm/275113452048 While I waited for this to arrive....I simply zip-tied the headlamp to my RedShift stem.
This Lezyne headlamp stem mount arrives with everything that you will require to smartly mount the headlight along with your RedShift suspension stem. It will mount to your choice of the front top two stem mount screws or the bottom two stem screws....whichever works best for you (I used the lower screws). I had posted some photos of my installation here somewhere.....but it results in a clean, smart looking, and very secure way to re-mount your headlight....in fact better than original in my opinion.
Here is your OEM stem uninstalled from the bike.....bottom view....and this 'notch' or cut-out is where the plastic mount atop your headlamp slides into the stem for mounting purposes. Once you give up the OEM stem you also give up this method of mounting the head lamp.
