{"product_id":"collins-tilton-hydraulic-release-bearing-input-shaft-cover-adapter","title":"Collins FR-S BR-Z FT-86 GR-86 Tilton Hydraulic Release Bearing Input Shaft Cover Adapter","description":"\u003cp\u003eThe factory clutch fork and pivot ball assembly in the TL70 transmission is a known weak point. Once clutch clamp loads increase, the OEM release mechanism becomes one of the first components to fail—cracked forks, broken pivot balls, inconsistent clutch release, and unnecessary downtime.\u003c\/p\u003e\n\u003cp\u003eOur Tilton Hydraulic Release Bearing (HRB) Input Shaft Cover Adapter eliminates those failure points entirely.\u003c\/p\u003e\n\u003cp\u003eDesigned specifically for the Toyota GR86, Subaru BRZ, Scion FR-S, and Toyota GT86 equipped with the TL70 transmission, this system replaces the factory mechanical release mechanism with a Tilton hydraulic release bearing, creating a stronger, more consistent, and race-proven solution for high-performance applications.\u003c\/p\u003e\n\u003cp\u003eWhether you're running an aggressive single-disc clutch, building a dedicated drift or road race car, or preparing for a custom twin-disc setup, this adapter is built to handle it. Thanks to Tilton's extensive range of Saab styled hydraulic release bearings with multiple piston heights and bearing diameters, this system is modular and can easily be configured for a wide variety of clutch stack heights and future upgrades.\u003c\/p\u003e\n\u003cp\u003eThis isn't a universal adapter or a one-size-fits-all solution.\u003c\/p\u003e\n\u003cp\u003eEvery dimension was developed from OEM Toyota engineering data, validated through real-world vehicle testing, and refined to ensure perfect alignment with the transmission input shaft. Each adapter is CNC machined on Japanese manufacturing equipment using dedicated fixtures to maintain exceptional concentricity and repeatable accuracy.\u003c\/p\u003e\n\u003cp\u003eThe result is a component you can trust whether you're swapping a high revving V8, banging gears at the track, or putting thousands of hard street miles on your build.\u003c\/p\u003e\n\u003cp\u003ePerformance doesn't have to come at the expense of drivability.\u003c\/p\u003e\n\u003cp\u003eOur design uses a 54 mm contact surface on the OEM pressure plate to create a mechanical advantage over the factory release system. The result is an incredibly light, smooth clutch pedal—even with pressure plates that would normally require significantly more effort.\u003c\/p\u003e\n\u003cp\u003eMany customers describe the pedal feel as similar to a stock '90s Honda Civic, giving you outstanding clutch modulation without sacrificing holding power.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eEliminates the factory clutch fork and pivot ball assembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRemoves one of the TL70 transmission's most common failure points.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eWorks on most RX8, and J160 transmissions as well.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eDesigned for the Toyota GR86, Subaru BRZ, Scion FR-S, and Toyota GT86.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCompatible with most all Tilton \"Saab\" bolt pattern Hydraulic Release Bearings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSupports high-clamp single-disc and custom twin-disc clutch systems(requires piston\/bearing hieght change in some cases).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePrecision CNC machined on Japanese equipment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEngineered using OEM Toyota data for precise fitment and alignment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLightweight, durable, and built for serious motorsport use.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eImproved clutch consistency, smoother engagement, and dramatically reduced pedal effort.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhen reliability matters, the factory release system simply isn't enough.
