K-Series Transmission Performance Select Springs
- Increases shifter centering force by approximately 50%
- Increased spring force makes shifter centering more "snappy"
- black-oxide coated for better oil retention
Description
Honda officially calls these the "First-2nd Select Spring" and "Fifth-Sixth Select Spring." They are the parts in your transmission that are (partially) responsible for your shifter centering itself when in neutral. By increasing the rate and preload of these springs, it's possible to realize a more decisive centering action for a sportier shift. ACUITY's K-Series Transmission Performance Spring Upgrade uses thicker wire and additional preload to provide a very satisfying, quick centering motion. This mod is particularly attractive because it provides such a noticeable change at a rather low price.

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
