Brian Crower Single Spring + Titanium Retainer Kit

Part #: BC0300

Overview

The Brian Crower Single Spring + Titanium Retainer Kit is a high-quality performance upgrade designed specifically for Toyota 2JZ engines, including the iconic 2JZGTE and 2JZGE models. Crafted for automotive enthusiasts and tuners aiming to maximize their engine’s potential, this kit enhances valve spring stability at high RPMs, supporting increased power output and improved reliability during aggressive driving, track days, or racing applications. It is an ideal choice for those seeking to push their engine’s limits while maintaining durability and consistent performance.

Key Features

This kit features precision-engineered components designed to improve valve train stability and response. Made from lightweight titanium, the retainers reduce overall valve train mass, contributing to higher RPM capabilities and reduced valve float. The single spring design ensures consistent pressure and reduces valve train wear, while the high-strength titanium retainers provide durability under demanding conditions. The kit is engineered for easy installation and compatibility with stock or upgraded valve springs, making it suitable for a wide range of performance builds.

Construction & Design

The retainers are crafted from aerospace-grade titanium, offering an optimal balance of strength and weight reduction. The springs are designed with high-quality steel, engineered to provide reliable tension and longevity under high-stress conditions. The components are machined to precise specifications, ensuring a perfect fit and smooth operation within the valve train assembly.

Performance & Response

This upgrade helps improve valve control at high RPMs, supporting more aggressive cam profiles and higher engine speeds. The reduced mass of the titanium retainers contributes to quicker valve response and less valve train fatigue, enhancing overall engine responsiveness and stability during high-performance driving.

Installation & Fitment

Installation requires removal of the existing valve springs and retainers, and should be performed by a qualified technician familiar with high-performance engine assembly. Proper verification of compatibility with your specific engine build is recommended to ensure optimal fitment and performance.

What’s Included

The package includes a complete set of titanium retainers and single valve springs necessary for a full upgrade of the valve train components on compatible Toyota 2JZ engines. Hardware and installation instructions are also provided to facilitate a straightforward upgrade process.
