Whether you are a spirited street driver or a track-focused performance enthusiast, these trailing arms provide a reliable upgrade to your vehicle’s suspension system.
Key Features:
Built with quality and performance in mind, the ISR Performance Rear Trailing Arms offer several advantages over factory components:
- On-car adjustability allows fine-tuning of rear suspension geometry for optimal alignment and handling balance.

Construction & Design:
The trailing arms are crafted from premium steel, chosen for its strength and resistance to flex under load. The robust construction ensures that suspension geometry remains consistent, even under high lateral and longitudinal forces. Adjustable spherical rod ends replace the factory rubber bushings, reducing deflection and providing more direct feedback from the rear suspension.
The design focuses on durability and precision, with each arm engineered to fit perfectly using existing mounting points. This eliminates the need for drilling or cutting, preserving the integrity of your vehicle’s chassis while delivering enhanced performance.
