Brian Crower Subaru BRZ/Scion FR-S/Toyota GT86 4UGSE Single Spring & Titanium Retainer Kit w/ Seats

Brian Crower is well-known for making strong internal engine components, and this single spring and titanium retainer kit is a prime example. If you're working on the 4UGSE engine found in your 2013-2017 Subaru BRZ, 2013-2016 Scion FR-S, or 2017 Toyota 86, this kit is designed to help you get more out of your valve train, especially as you push the engine to higher RPMs.

This kit includes single valve springs, titanium retainers, and valve seats. The titanium retainers are notably lighter than stock, which helps reduce the mass the valvetrain has to move. This improved valve control means the valves can follow the camshaft profile more accurately at higher engine speeds, which is crucial for making power and maintaining reliability when you're revving the engine out.

When rebuilding or modifying the top end of your 4UGSE engine, using well-built components like these from Brian Crower can make a significant difference in performance and durability. Make sure to consult your service manual for proper installation procedures and any additional hardware you might need.
