Holden Colorado Crown Wheel and Pinion Fitment
This set suits 2012-and-later Holden Colorado differentials running standard rotation gearing. The 3.73 ratio was the factory manual-transmission ratio from launch in 2012 through to the 2017 update, when Holden shortened it to 4.10. It’s a popular replacement ratio for manual Colorado owners running close to stock tyre sizes, striking a balance between highway cruising and everyday acceleration. Check your build date and transmission to confirm which ratio your vehicle needs.

Workshop customer · Christchurch · Example review Order before 2pm, on the bench next morning. Preload sorted so we do not see them back. Saves us a hoist for a week every time.
★★★★★ Sorted the clunk
