Always verify your vehicle’s suspension configuration before purchasing.
Restore Proper Rear Camber
Lowering springs and coilovers frequently create excessive rear negative camber that factory suspension components cannot fully correct.
The Godspeed AK-154-B arms allow you to:
- Restore factory alignment specifications
- Correct excessive negative camber
- Reduce uneven tire wear
- Improve rear suspension geometry
- Optimize handling for street or performance driving
The ±3° adjustment range provides ample flexibility for most lowered GS applications.
Spherical Bearings for Precision
Instead of traditional rubber bushings, these camber arms use spherical bearings to minimize suspension deflection.
Benefits include:
- Improved suspension precision
- More consistent alignment under load
- Better steering response
- Enhanced cornering stability
- Increased feedback during spirited driving
Because spherical bearings reduce compliance, they may transmit slightly more road noise and vibration than factory rubber bushings.
Heavy-Duty Steel Construction
Godspeed manufactures these arms from heavy-duty steel alloy for strength and durability.
Construction highlights include:
- Heavy-duty steel alloy
- Precision welds
- Corrosion-resistant powder coating
- Durable finish for year-round driving
- Built for both street and occasional track use
The powder-coated finish helps protect against rust and corrosion while maintaining a clean appearance.
Direct Replacement Design
The AK-154-B kit is engineered as a direct replacement for the factory rear upper control arms.
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 hardware to factory specifications.
- Complete a professional four-wheel alignment.
Professional installation is strongly recommended, as installation instructions are not included.
Benefits After Installation
Properly adjusted rear camber can help provide:
- Longer tire life
- Improved rear grip
- Better cornering stability
- More predictable handling
- Factory-spec alignment after lowering

Final Verdict
The Godspeed AK-154-B Adjustable Rear Upper Camber Arms are an excellent suspension upgrade for 2013–2019 Lexus GS200t, GS300, and GS350 RWD models equipped with lowering springs or coilovers. Their heavy-duty steel construction, precision spherical bearings, and ±3-degree adjustment range provide the alignment flexibility needed to improve handling while reducing uneven rear tire wear.
For Lexus GS owners looking to maintain proper suspension geometry without sacrificing durability, the AK-154-B delivers an excellent balance of performance, reliability, and value.
