2013–2017 Subaru BRZ / 2017 Toyota 86 4UGSE
BC0650
Overview:
The Brian Crower Single Spring & Titanium Retainer Kit is a precision-engineered valve spring upgrade designed specifically for the Subaru BRZ (2013–2017) and Toyota 86 (2017) equipped with the 4UGSE engine. This kit replaces the factory dual spring setup with a high-performance single spring system paired with lightweight titanium retainers, delivering enhanced valvetrain stability and durability under demanding conditions. Ideal for enthusiasts seeking improved engine response and reliability during spirited driving or track use, this kit helps maximize the potential of your naturally aspirated boxer engine.
Brian Crower’s reputation for quality and performance is evident in this kit, which is engineered to withstand higher RPMs and aggressive cam profiles while reducing valvetrain mass. This upgrade is a smart choice for those upgrading their camshafts or building a performance-oriented Subaru BRZ or Toyota 86.
Key Features:
This valve spring and retainer kit offers a range of benefits tailored to performance applications:
Construction & Design:
The Brian Crower kit features premium-grade valve springs manufactured to exacting tolerances for consistent spring pressure and durability. The single spring design simplifies the valvetrain while maintaining optimal valve control, reducing the risk of coil bind and valve float. The titanium retainers are precision-machined from aerospace-grade titanium alloy, offering exceptional strength-to-weight ratio and corrosion resistance. This combination reduces reciprocating mass, allowing the engine to rev more freely and reliably at higher RPMs.
Every component undergoes rigorous quality control to ensure fitment accuracy and performance consistency. The springs are shot-peened and heat-treated to enhance fatigue life, making this kit a reliable upgrade for performance enthusiasts.
Installation & Fitment:
This kit is a direct fit replacement for the factory valve springs and retainers on Subaru BRZ models from 2013 through 2017 and Toyota 86 models from 2017 equipped with the 4UGSE engine. Installation requires standard valve spring compressor tools and mechanical knowledge of cylinder head disassembly. No modifications to the cylinder head or valves are necessary, ensuring a straightforward upgrade process. Proper installation torque and valve lash settings should be followed to guarantee optimal performance and longevity.
What's Included:
Ideal For:
This Brian Crower Single Spring & Titanium Retainer Kit is ideal for Subaru BRZ and Toyota 86 owners who are upgrading camshafts, building performance engines, or seeking improved valvetrain stability for spirited street driving and track use. It is especially beneficial for those pushing their naturally aspirated 4UGSE engines to higher RPMs or installing aggressive valve timing components.
Brian Crower (BC) supplies performance engine internals and valvetrain components aimed at serious builds, including stroker kits and rotating assemblies. Known for system-matched parts designed to work together, BC products are a go-to for enthusiasts chasing more displacement, higher RPM capability, and stronger bottom-end reliability in high-output street or track applications.

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!
