Correct Rear Camber After Lowering
Factory rear suspension offers little adjustment once ride height has been reduced.
The AK-154-A allows you to:
- Restore factory alignment
- Correct excessive negative camber
- Improve rear tire contact
- Reduce uneven tire wear
- Optimize rear suspension geometry
Its ±3° adjustment range provides ample correction for most lowered street and performance vehicles.
Heavy-Duty Steel Construction
Godspeed manufactures the AK-154-A from heavy-duty steel alloy for exceptional durability.
Construction highlights include:
- Heavy-duty steel alloy
- Precision-welded construction
- Powder-coated corrosion-resistant finish
- High-strength adjustment mechanism
- Built for street and motorsports use
The powder coating helps resist corrosion caused by moisture, road salt, and debris.
Performance Spherical Bearings
Instead of factory rubber bushings, these control arms utilize precision spherical bearings.
Benefits include:
- Reduced suspension deflection
- More accurate alignment under load
- Improved cornering stability
- Sharper suspension response
- Consistent wheel geometry during aggressive driving
Because spherical bearings are firmer than rubber bushings, expect increased road feel along with slightly higher levels of noise, vibration, and harshness (NVH).
Improve Handling & Tire Life
Correct rear camber settings provide several noticeable improvements.
Benefits include:
- Longer tire life
- Better rear grip
- Improved cornering balance
- Increased chassis stability
- More predictable handling
These advantages are especially noticeable after installing lowering springs or coilovers.
Street & Track Ready
Godspeed engineered these camber arms for multiple driving styles.
Ideal for:
- Daily drivers
- Lowered street builds
- Canyon driving
- Autocross
- Track days
Proper alignment settings should always be tailored to your driving goals.
Direct Bolt-On Installation
The AK-154-A installs using factory mounting locations.
Typical installation includes:
- Raise and safely support the vehicle.
- Remove the factory rear upper control arms.
- Install the Godspeed adjustable camber arms.
- Set an initial camber adjustment.
- Torque all fasteners to factory specifications.
- Perform a professional four-wheel alignment.
Professional installation is strongly recommended.
