Correct Negative Camber Before It Eats Your Rear Tires
Lowering an S-chassis or Z32 pushes rear camber further negative than the factory upper control arm bushing can handle, chewing up the inside edge of your rear tires. This Whiteline KCA347 camber adjusting kit replaces the rigid factory upper control arm bushing with an eccentric adjustable design, giving you the range to bring rear camber back into a usable window.
Key Features
- Adds significant additional rear camber adjustment range at the upper control arm
- Corrects excessive negative camber caused by lowering springs or coilovers
- Extends rear tire life by keeping contact patch more even across the tread
- Durable polyurethane bushing resists the wear that leads to factory bushing failure
- Direct replacement using the factory upper control arm mounting location
- KCA347 shares the same rear upper control arm design across the S13, S14, and Z32 platforms

FAQ
What is the KCA347?The KCA347 is a Whiteline rear camber adjusting kit that replaces the factory upper control arm bushing on the Nissan 240SX and 300ZX, adding the range needed to correct excessive negative camber.
Why does my rear camber need correcting after lowering my car?Lowering the ride height changes suspension geometry and pushes rear camber further negative than the factory bushing allows, which this kit is designed to correct.
Will this kit help my rear tires wear more evenly?Yes, correcting excessive negative camber back toward a proper alignment spec reduces uneven inside edge wear on the rear tires.
Do I need an alignment after installing this kit?Yes, since this kit is specifically designed to change camber angle, a full alignment is required after installation to set your desired specification.
Does this kit replace the entire control arm?No, this kit replaces the bushing within your factory upper control arm rather than the arm itself.
Can I install this kit in my home garage?Yes, most installers with basic hand tools and jack stands can complete this swap, though a proper alignment afterward requires shop equipment.
Will this kit work with coilovers or a lowering spring setup?Yes, this kit is commonly installed alongside lowering springs or coilovers specifically to correct the camber shift that comes with a lower ride height.
Is this kit front or rear specific?This kit is for the rear upper control arm only and does not include any front suspension components.
Install Instructions
- Raise and safely support the rear of the vehicle on jack stands
- Remove the rear upper control arm from its chassis and knuckle mounting points
- Press out the factory bushing from the control arm
- Install the new Whiteline eccentric adjustable bushing into the control arm
- Reinstall the control arm and torque all fasteners to factory specification
- Lower the vehicle and have a professional alignment performed to set camber
