PRODUCT DETAIL

Key Features & Description

Features:

  • Reduces steering play
  • Improves steering control
  • Cuts down driver fatigue
  • Provides for safer driving

Death Grip Idler Support Kit Provides a Stronger Pivot 

When upgrade to larger tires of 35" or larger, your stock idler pivot assembly will quickly reveal itself as not being able to handle the stress. It will likely wear out, bend, and even break under this new pressure. With the 2011-2025 GM 6.6L Duramax 2500HD/3500HD Kryptonite Death Grip Idler Support Kit, you can conveniently upgrade this assembly with a stronger and more durable alternative that features tapered roller bearings that provide a solid pivot point for your steering components. Without a high-quality upgrade like this one, your stock idler pivot assembly will cause tie rod issues and move uncontrollably over rough terrain. You could experience devastating damage including idler arm rubbing the transmission cooler lines or motor mount, pitman arm, idler arm, and tie rod breakage.

Parts Included:

  • (1) Kryptonite Death Grip Idler Support
  • (1) Installation hardware and instructions
