If the spring rate is for your weight , then yes , it will help as far as comfort goes , will it be a dramatic difference , maybe , maybe not , springs are made for the weight of the rider to keep the suspension travel where it should be , when it should be in that position , in other words , when you are heavier than the OEM spring rate was designed for , the suspension squats down into the stroke , you only have so much travel , the suspension is designed to open valving at certain points along that travel , if the bike is already squatting , then it is already past the initial part of the stroke and heading to the middle of the stroke , so what happens is you get harshness because the valving is opening at the wrong time because the suspension has already gone past the point it would have opened , it takes movement to get oil to flow thru the shim stack , the faster the movement the more the shim stack reacts , as well as the time frame the movement is taking place , it stays open longer if the suspension is traveling thru its entire stroke , if the stroke is already partially used up , then the distance is less , the force is less and the time is less , so less oil flows , the less shims move and the harsher the suspension feels
So to answer your question , it will help if the spring rate is for your weight , if you weigh more than the rate of even the new spring , then it will be less of a improvement ...... but .......... because the adjustability of this shock (and forks for that matter) is minimal at best , you are not going to notice a dramatic difference , so in a way it is like "putting lipstick on a pig" , I guess the question is , how much is the comfort worth to you ??? , if you will be happy with any improvement , then you helped the situation with minimal expense considering the alternatives .... if you were expecting a big change , then you are going to be disappointed somewhat .... how much depends on your expectations ..... Race Tech along with Ohlins makes suspension upgrades for this bike , I believe the Ohlins is actually cheaper than the Race Tech setup , both include a upgraded shock , and new fork springs , I believe the Ohlins setup has inserts (Cartridges) that give you a level of adjustability that actually will make a difference ...... but the cost goes way up versus a shock spring ...so theres that ....
