2023–2026 Toyota GR Corolla
5017
Overview:
The GSC Power Division Conical Valve Spring and Titanium Retainer Kit is engineered specifically for the 2023 and newer Toyota GR Corolla, as well as compatible with the 2019+ Toyota GR Yaris. This high-performance valve spring kit is designed for enthusiasts seeking enhanced valvetrain stability and durability under aggressive driving conditions. By utilizing true conical valve springs, this kit offers superior control over valvetrain harmonics compared to traditional cylindrical or beehive springs, resulting in improved engine reliability and responsiveness.
Whether you are a spirited street driver or a track-focused enthusiast, this kit helps maintain precise valve control at high RPMs, supporting your vehicle’s performance upgrades and ensuring consistent power delivery.
Key Features:
This valve spring and retainer kit incorporates advanced design and materials to optimize valvetrain performance:
Construction & Design:
The kit features true conical valve springs, a proven design in motorsports and high-performance applications. Unlike traditional cylindrical springs, conical springs taper in diameter, which helps reduce harmonic vibrations that can cause valve float or instability at high engine speeds. This design improves valvetrain control and reduces the risk of component fatigue.
The titanium retainers are lightweight yet strong, reducing the overall mass of the valvetrain assembly. This reduction in reciprocating mass allows for quicker valve response and less stress on valve train components, contributing to improved engine efficiency and durability.
Installation & Fitment:
This valve spring and retainer kit is a direct bolt-on upgrade for the 2023 through 2026 Toyota GR Corolla, as well as the 2019 and newer Toyota GR Yaris. It installs using factory mounting points and requires no modifications to the cylinder head or valvetrain components.
No cutting, drilling, or special tuning is required, making it an ideal upgrade for enthusiasts looking to enhance their engine’s valvetrain performance without extensive machine work.
What's Included:
Ideal For:
This kit is perfect for performance enthusiasts and racers who demand precise valvetrain control at high RPMs. It is especially beneficial for those upgrading their engine with higher lift cams or forced induction, where valve spring stability is critical to prevent valve float and maintain engine reliability.
GSC Power Division specializes in high-performance camshafts and valvetrain components for import engines, including Subaru, Mitsubishi, Toyota, and Nissan models. Their products are designed to enhance engine performance in both street and race applications, offering improved mid-range and top-end power without sacrificing low-end torque.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
