Correct Rear Camber After Lowering
Factory rear suspension offers limited camber adjustment once ride height has been reduced.
These adjustable control arms allow you to:
- Correct excessive negative camber
- Restore factory alignment
- Improve rear tire contact patch
- Reduce uneven tire wear
- Fine-tune suspension geometry
The estimated ±3° adjustment range accommodates most lowered street and performance setups.
Pillowball Bearings for Maximum Precision
Unlike factory rubber bushings, these control arms use performance pillowball (spherical) bearings.
Advantages include:
- Reduced suspension flex
- Improved suspension precision
- Better wheel control
- Faster steering response
- Consistent alignment during hard cornering
Because spherical bearings are firmer than rubber bushings, expect increased road feel and slightly higher levels of noise, vibration, and harshness (NVH).
CNC Tubular Steel Construction
The AJP Distributors camber arms are engineered using CNC-machined steel alloy for improved durability.
Construction highlights include:
- CNC-machined steel alloy
- Tubular performance design
- Industrial blue powder-coated finish
- Corrosion-resistant protection
- Low-profile upper plate for added suspension clearance
The tubular design also helps reduce interference around surrounding suspension components.
Improve Handling
Correct rear camber settings improve overall chassis performance.
Benefits include:
- Better rear grip
- Improved cornering stability
- More predictable handling
- Sharper suspension response
- Increased tire lifespan
These benefits become especially noticeable after lowering the vehicle.
Direct Bolt-On Installation
These control arms install using factory mounting points.
Typical installation steps include:
- Raise and safely support the vehicle.
- Remove the factory rear upper control arms.
- Install the adjustable AJP Distributors control arms.
- Set an initial camber adjustment.
- Torque all fasteners to specification.
- Perform a professional four-wheel alignment.
Installation instructions are not included, and professional installation is strongly recommended.
Benefits After Installation
Properly adjusted rear suspension can provide:
- Longer tire life
- Improved rear suspension geometry
- Better handling balance
- Increased high-speed stability
- Factory alignment after lowering
