Good To Know

Q: Will this kit work on a Honda Rubicon 500 4×4 from 2014? A: No, this kit is specifically for 2015‑2019 models with a 92mm standard bore. Earlier years may use a different bore or piston design.

Q: Do I need to replace the cylinder along with this kit? A: If the cylinder shows scoring, wear, or out‑of‑round conditions, a rebore to an oversized piston is recommended. For a standard bore kit, the cylinder must be within factory specifications.
