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

When a Nissan 240SX is lowered, the rear wheels gain negative camber that the factory arms cannot take back out. The ISR Performance rear upper control arm for the 1989 to 1998 S13 and S14 gives you an adjustable upper link so rear camber can be set where you want it, whether that is near zero for tire life or a deliberate negative figure for grip.

What the rear upper arm controls

On the S-chassis multi-link rear, the upper arm locates the top of the knuckle and sets camber. Shortening or lengthening it tips the wheel in or out. Adjustable arms are the standard fix for excessive rear camber on coilover equipped cars and for tuning rear grip on a drift or track setup.

Why choose the ISR arm

• Adjustable length for rear camber correction
• Replaces the non-adjustable factory arm and its aged bushings
• Works alongside ISR toe rods and traction rods for full rear geometry control

Vehicle application

Nissan 240SX 1989 to 1998, S13 and S14 chassis.

Fitting advice

Match the arm to factory length before installation so the car is driveable to the alignment shop, torque the pivot bolts with the suspension loaded at ride height, and have camber set on a rack.
