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

The ISR Performance Pro Series Front Tension Control Rods are the top-tier adjustable front tension rod set for the 1989-1994 Nissan 240SX (S13). After years of success with the original Street Series suspension arms, the Pro Series stepped up the construction with Japanese spherical rod bearings, larger rod ends, dust boots, thicker material, and added bracing. The same arms used on Patrick Goodin's 1000+hp Formula Drift S-Chassis, built to take serious abuse on the street, track, or competition drift use.

What It Does

Front tension control rods (also called caster rods or front compression rods) set caster geometry and resist the longitudinal forces hitting the front lower control arm under braking and over bumps. The factory tension rod on the S-Chassis uses a rubber bushing that flexes under hard use and is a known weak point. Adjustable Pro Series rods let you dial in caster, replace tired factory bushings with proper spherical bearings, and handle real abuse without flexing.

Pro Series Improvements Over Street Series

• Japanese spherical rod bearings (vs. lower-cost rod ends on the Street Series)
• Larger rod ends for higher load capacity
• Rod end dust boots to protect against contamination
• Thicker material throughout
• Added bracing for stiffness under load

Real-World Validation

Same arms used on Patrick Goodin's professional Formula Drift S-Chassis at 1000+ horsepower. If they hold up to a full season of pro-level drift competition, they'll handle anything a street or grassroots build can throw at them.
