The PSP-SUS-237 connects the rear sway bar to the chassis with a rigid polyurethane bushing pressed into a 6061-T6 aluminum arm, eliminating the bushing flex that makes aftermarket sway bars feel soft and imprecise. The result is sharper turn-in, reduced body roll, and a more direct transfer of sway-bar forces to the suspension

Asked Questions\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre the PSP-SUS-237 endlinks adjustable in length?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The PSP-SUS-237 is a fixed-length endlink designed for direct OEM replacement. The fixed geometry ensures proper bushing alignment and eliminates the need for setup adjustments during installation. If you need adjustable endlinks for corner-balancing or ride-height changes, PERRIN also offers the PSP-SUS-235 spherical bearing endlinks with adjustable length.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between PERRIN polyurethane endlinks and OEM rubber endlinks?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOEM endlinks use rubber bushings that deflect under load, partially absorbing sway-bar input before it reaches the suspension. This deflection dulls turn-in response and allows the sway bar to twist under high cornering loads. The PSP-SUS-237 uses 95a durometer polyurethane bushings pressed into 6061-T6 aluminum arms. The stiffer bushing compound transfers sway-bar forces more directly to the chassis, improving cornering flatness and feel without the noise or maintenance that comes with solid spherical bearings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo the PSP-SUS-237 endlinks fit the 2022+ Subaru BRZ and Toyota GR86?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The PSP-SUS-237 is confirmed to fit both the 2022-2025 Subaru BRZ and the 2022-2025 Toyota GR86. These second-generation ZD8 and ZN8 platforms share rear suspension geometry with the earlier ZC6 BRZ and ZN6 86\/FR-S, so the PERRIN endlink is a direct fit across all generations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill the PSP-SUS-237 fit the Subaru WRX STI?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The PSP-SUS-237 fits the 2009-2021 Subaru WRX STI. The STI shares the same rear suspension mounting points as the WRX for these model years, so no adapters or modifications are needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to upgrade my sway bar to use these endlinks?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The PSP-SUS-237 endlinks work with the factory OEM rear sway bar as well as any aftermarket rear sway bar. Many owners install them alongside the factory bar as a preemptive upgrade, since OEM endlinks are a known failure point when a larger-diameter aftermarket sway bar increases the forces on the endlink bushings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill installing PERRIN endlinks void my Subaru factory warranty?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnder the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless the manufacturer can prove the part directly caused the failure in question. Installing the PSP-SUS-237 rear endlinks does not automatically void your Subaru powertrain or vehicle warranty. If you have concerns about specific warranty terms at your dealership, review your warranty documentation before installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre the PSP-SUS-237 endlinks noisy on rough roads or daily driving?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo, polyurethane bushings are substantially quieter than spherical bearings or heim joints. The 95a durometer compound provides enough compliance to absorb minor road noise and vibration without the clunking that metal-on-metal spherical bearings can develop over time. PERRIN specifically chose this durometer to replicate the feel of spherical bearings while keeping the endlink suitable for daily driving and track use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tools do I need to install the PSP-SUS-237 rear endlinks?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInstallation requires basic hand tools: a floor jack and jack stands or a vehicle lift, a 14mm and 17mm socket (or open-end wrench), a torque wrench, and anti-seize or assembly lubricant for the bushing contact surfaces. No specialized suspension tools or alignment equipment are required for the endlink swap itself, though a wheel alignment is recommended any time rear suspension components are replaced.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eRaise the vehicle and secure it on jack stands or a lift.
