PERRIN PSP-SUS-237 Rear Endlinks Polyurethane for WRX STI BRZ GR86

PERRIN Rear Endlinks – Polyurethane (PSP-SUS-237)

The PERRIN Rear Endlinks with Polyurethane Bushings (PSP-SUS-237) are designed to fix a well-known weak point in the factory suspension. OEM rear endlinks can flex or fail—especially when paired with larger aftermarket sway bars—reducing handling response and consistency.

PERRIN solves this with 6061-T6 aluminum endlink bodies and 95a durometer polyurethane bushings, delivering a solid sway bar-to-chassis connection without the noise or harshness of spherical bearings. The result is sharper handling, improved predictability, and long-term durability in all driving conditions.

Key Features

• Upgrades a common OEM rear endlink failure point

• 6061-T6 aluminum endlink bodies for strength and rigidity

• 95a durometer polyurethane bushings for a firm, controlled feel

• Delivers performance similar to spherical bearings without added NVH

• Corrosion-resistant bushings ideal for harsh climates

• Excellent match for larger aftermarket rear sway bars

• Includes high-strength Grade 8 hardware for track-ready reliability
