EDR ZX-6R 636 ZX6 Race kit valve spring kit 2009 - 2026

EDR Performance spec race kit valve springs

2009-2026 ZX6R, ZX636

Our race kit valve springs are Japanese made "beehive" and exceed oem quality. We take it a step further and micro-finish them in house before shipping.

These springs are a must for any racing ZX6R/636 especially the 2024+ generation where Kawasaki cut cost/performance of the oem valve springs.

Our springs come complete with retainers and are 100% micro-finished in house. 

They use oem retainers, spring seats and keepers (not included!)

**NOTE 2024+ Generation must select "Retainers"

2009-2023 EDR highly recommends you replace these at the same time, the oem retainers wear fast so replacing at the same time just makes sense

Typically ship within 5-7 business days
