About this part

This is a set of four replacement big bore shock bladders from Kyosho. The bladders go inside the shock absorber caps to seal the shock and stop the silicone shock oil from leaking out.

Note:
These shock bladders are only for the Kyosho big bore shocks KYOIF346,  KYOIF349, and  KYOIS105.

What is the diameter???????????????????????????????????

JordanVerified owneron Kyosho Big Bore Shock Diaphragm (4)

As with other review, I use these on my RC8.2 and RC8.2e, but I'm using them in the GHEA "big dome" shock caps. These are good bladders, even when used in non-Kyosho cars.

Tom EricksonVerified owneron Kyosho Big Bore Shock Diaphragm (4)

I have an RC8.2 and RC8.2e and use these bladders in the stock shocks with the stock caps. They are much plusher than the stock bladders and emulsion set-up. I would recommend these to anyone out there

Best bladders on the market. Regaurdless of brand of car, if these fit your shocks- Run em'. You will definitelly notice a dfference in rebound and overall shock consistency.

What reviewers say

Reviewers largely agree the diaphragms perform well, with verified owners running them on Kyosho RC8.2 and RC8.2e cars and in GHEA big-dome shock caps. Users report they feel plusher than stock bladders and emulsion setups, with noticeable gains in rebound and shock consistency. One reviewer notes they also work on non-Kyosho cars if they fit. One review asks for the diameter, which is not answered in the reviews. Overall sentiment is uniformly positive, though the sample is small and not all reviews are substantive.
