Keep Power Down Without Wheel Hop
Hard launches and aggressive throttle application on the 370Z and Z platform can flex the factory rear traction arms, allowing the rear suspension to deflect and causing wheel hop or inconsistent power delivery. This Whiteline KTA442 adjustable rear traction arm kit adds rigidity and adjustment range to keep the rear suspension geometry locked in under hard acceleration.
Key Features
- Direct replacement adjustable rear traction arm kit
- Reduces suspension deflection under hard acceleration
- Helps eliminate wheel hop from flexing factory arms
- Adjustable design allows rear geometry fine tuning
- KTA442 uses durable spherical bearings for consistent control

About Whiteline
Whiteline builds performance suspension arms engineered to control rear geometry under the stress of hard acceleration and cornering. Their traction arm kits reduce deflection that leads to wheel hop and inconsistent handling.
FAQ
What is the KTA442?
The KTA442 is a Whiteline adjustable rear traction arm kit for the Nissan 370Z and Z that reduces suspension deflection under hard acceleration.
What causes wheel hop on the 370Z during hard launches?
The factory rear traction arms can flex under load, allowing the rear suspension to deflect and cause wheel hop or inconsistent power delivery.
Does this fit the new Nissan Z?
Yes, this traction arm kit is compatible with both the 370Z and the newer Nissan Z platform.
Is this a direct bolt in replacement?
Yes, this traction arm uses the factory mounting points for a direct bolt in installation.
Does this arm offer adjustment?
Yes, the KTA442 is adjustable, allowing fine tuning of rear suspension geometry.
Will this help with drag racing or hard launches?
Yes, the added rigidity in this traction arm helps keep power down and reduces wheel hop during hard launches.
Do I need an alignment after installing this arm?
Yes, a rear alignment check is recommended after replacing any traction arm component.
Does this use spherical bearings or bushings?
The KTA442 uses durable spherical bearings for precise, consistent control.
