Not very effective in Normal spring.
Used in 4jp5APRIO
I was considering whether to use a stiffer center spring when I remembered this product, so I purchased it.
I thought that if I put the BearingSlider in before stiffening the Sensep, I would be able to apply a little more load to the Spring than in the OEM condition.
I'm not sure how effective it is, but I think it will be useful when I replace the Sensep and make it harder, because I think it will absorb the twisting.
As for the quality and texture, well, there is a slight BALI on the processed finish, so I lightly removed the BALI with sandpaper before injuring my hand.
The precision of the ball in the Slide section was also gurgling when turned by hand with load, so I put a few drops of Bell Hammer Gold on it and turned it by hand until it became accustomed to it.
The gurgling feeling is almost gone, but I think it is better to degrease the oil thoroughly before assembling because it may fly out.
I don't think it is necessary to add oil to the parts since they are not usually high-revving parts.
