Cognito PISK Kit 110-90772

Upgrade your steering system with the Cognito PISK Kit 110-90772 for 2011–2025 Duramax LML and L5P trucks. This kit improves steering stability, reduces wear, and strengthens weak factory components.

Fix Common Steering Wear Issues

GM trucks often experience wear in the pitman and idler arms. Because of this, the center-link can move forward and backward over time.

The Cognito PISK Kit 110-90772 solves this problem by adding proper support. As a result, it stabilizes the steering system and reduces unwanted movement.

Improved Steering Stability and Control

This kit supports both the pitman and idler arms. Because of this, it helps maintain proper alignment of the center-link.

In turn, your truck delivers more precise steering. In addition, it reduces play in the front end, which improves overall driving confidence.

Patented Design for Proven Performance

Cognito engineered this kit using a patented design. Because of this, it delivers reliable and consistent results.

This design eliminates the forward and rearward movement of the center-link. As a result, it protects critical steering components from premature wear.

Built for Stock and Lifted Applications

The Cognito PISK Kit 110-90772 works with stock height trucks. In addition, it supports lifted setups as long as the OE center-link remains in the stock location.

Because of this, it fits a wide range of builds. So, whether your truck is stock or lifted, you can benefit from improved steering performance.

Durable Construction with Complete Kit

Cognito builds this kit for long-term durability. Because of this, it holds up under heavy use and demanding conditions.

In addition, it includes all necessary mounting hardware. So, you can complete installation without needing extra parts.
