Sierra 2500HD / 3500HD 2011-2026 GMC - SS Series Center Link (upgrade) by Kryptonite

The Kryptonite KR11SSU34 Solid Center Link for the GMC Sierra 2500HD/3500HD is an upgrade for customers that already have Kryptonite tie rods and a factory center link.  It is engineered for unmatched durability and precision steering. It maintains all factory alignment specs and steering geometry while significantly strengthening your truck’s front-end components. Modeled after the H1 Military Hummer's center link, this design is far superior to the factory steering setup found on non-Hummer GM HD trucks, delivering enhanced control and longevity.

Crafted from 1144 stress-proof carbon steel, this 1-5/8-inch hexagonal center link is built to handle extreme conditions. With a tensile strength of 115,000 psi and yield strength of 100,000 psi, it significantly outperforms standard 4140-4130 chromoly steel, making it one of the strongest center links available. This center link is compatible with GM or aftermarket Idler and Pitman arms and is designed to work seamlessly with the PISK support system for even more excellent stability. If additional reinforcement is needed, the PISK system can be added separately. This upgrade is specifically designed for customers looking for an extreme-duty replacement with Kryptonite tie rods on a factory center link.

Before purchasing this center link upgrade, it is essential to verify whether your tie rod bodies use 3/4" threads or 7/8" threads to ensure proper fitment. This kit includes one Kryptonite Series Solid Center Link and two Kryptonite Series Inner Tie Rod Ends, which are compatible only with Kryptonite tie rods.

Backed by Kryptonite’s No Fine Print Lifetime Warranty, this center link is built to withstand extreme off-road abuse, heavy towing, and high-performance driving. If it breaks, Kryptonite will replace it—no questions asked. To qualify for warranty coverage, products must be purchased from an authorized dealer and registered within 90 days of purchase.
