ISR Performance Pro Series Rear Upper Control Arm - Nissan 240sx 89-98 S13/S14

The ISR Performance Pro Series Rear Upper Control Arms are the top-tier adjustable rear camber arm set for the 1989-1998 Nissan 240SX (S13 and S14). Pro Series 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.

What It Does

Rear upper control arms set rear camber on the S-Chassis. Lowering naturally pulls the rear into excessive negative camber, and adjustable upper control arms let you correct that back to your target alignment. Whether you're going back to factory spec on a daily driver or dialing in aggressive negative camber for drift or track use, these are the right arms for the job.

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.
