Dial In Your Dampers with Kyosho IF347-145B

For precise suspension tweaking, the Kyosho IF347-145B shock pistons are built to improve damper consistency on big shocks. With a 1.4mm orifice and a 5-hole pattern, they let you refine oil flow and tune rebound and compression feel without complex mods.

How These Work on Big Shocks

The Kyosho IF347-145B pistons are aimed at drivers who want smoother handling and repeatable performance. Fitting these pistons adjusts the internal flow characteristics so your dampers respond more predictably on rough or smooth surfaces, making setup changes easier trackside.

These pistons fit a broad range of models that use big shock bodies. Installation is straightforward: remove the old pistons and insert the IF347-145B units, making sure they sit square in the shock cylinder. They are a low-cost way to refresh worn internals or test a different damping profile.
