ISR Performance Pro Series Front Tension Control Rods - Nissan 240sx 89-94 S13

Front caster on an S13 is set by the tension rod, and the factory rubber-bushed rod deflects under braking and gives up precision the moment the car is lowered. The ISR Performance Pro Series front tension control rods for the 1989-1994 Nissan 240SX S13 replace that compliant link with an adjustable, spherical-bearing rod so you can set caster where you want it and have it stay there.

How the Pro Series differs

ISR's Street Series tension rods have been a popular S13 upgrade for years. The Pro Series takes that design and reinforces every part of it:

• Japanese spherical rod bearings for clean, bind-free movement
• Larger rod ends to handle braking loads
• Rod end dust boots to keep debris out
• Thicker materials in the rod body
• Added bracing for rigidity

Competition background

These are the same rods ISR runs on Patrick Goodin's professional Formula Drift race car, holding up to the abuse of 1000+hp. That background is why the Pro Series is appropriate for serious track or drift builds as well as a sharpened street car.

Fits

• 1989-1994 Nissan 240SX (S13 chassis)

Looking for the S14? ISR offers a separate Pro Series tension rod for the 1995-1998 chassis.

Setup

Added caster improves straight-line stability and increases camber gain as the wheel turns, which helps front grip mid-corner. Set both sides equal, then confirm with an alignment. Suitable for street and track use.
