"Definitely is a lot stronger than stock. It definitely tightened up my steering play and I’m definitely not pulling as much when I lock it in four-wheel-drive."

KIT CONTENTS:
- Kryptonite SS Center Link and Tie Rod Package
- Kryptonite Idler Support
- Kryptonite Idler Support Frame Gusset
- Kryptonite Death Grip Pitman Arm
- Kryptonite Death Grip Idler Arm
IMPORTANT NOTE:
- If installing Kryptonite SS Series centerlink on a leveled or lifted truck you may need to install longer sway bar end links depending on how high the torsion bars have been adjusted. We recommend the Kryptonite HD sway bar end links. This kit will only work on trucks that keep the center link in the factory position. If your truck has been lifted, make sure your lift kit is a spindle style kit, not a control arm drop. This steering system is modeled after the Center Link on the H1 Military Hummer, this is a much stronger design when compared to what's offered from factory on all GM HD Trucks.
- This Kit will not function properly with older style "Drop Centerlink" Lift kits. Or "Drop Control Arm" Lifts kits. For example; older Pro Comp and early 2000's Fabtech Kits.
- Gold Zinc Coated Grade Ten Nylocs Hardware
- Corrosion Protected Snap Rings
About Kryptonite Products
Are you interested in replacing and upgrading your steering and suspension for the absolute last time with a product that will not only last as long as the rest of your truck, but also improve the suspension and steering feel? Kryptonite products are over-engineered, made in the USA products and most are even backed by a lifetime warranty. The Kryptonite No Fine Print Lifetime Warranty specifically states "Kryptonite steering and suspension components are warrantied for life to their original purchaser. This warranty is against any manufacturer defects, premature wear or breakage. Race it, jump it, off road it, wreck it, lift it, lower it, sled pull it, I think you get it? We dont care. If you can break it we will replace it." That's a pretty bold statement and would require a company that builds a solid product to offer it and still be in business.
Maybe youve heard of Kryptonite, maybe not. For those that have not heard of Kryptonite, they are a steering and suspension manufacturer on a mission to offer the absolute best in steering and suspension options for trucks and even side by sides. Theyve spent years developing and perfecting these components, and all of them are proudly Made in the USA.
KRYPTONITE STEERINGMany would argue that Kryptonite got its foot in the door with their massive steering tie rods for Chevy 2500HD and 3500s, or maybe it was their upper control arms for this application. Maybe so, and wed have to agree they did a fantastic job in creating a bulletproof solution. From these initial proving grounds, Kryptonite has vastly expanded their portfolio in providing steering linkages for Ram and Fords, Lifetime Warranty Wheel Bearings, ball joints, centerlinks, pitman and idler arms, and even complete suspension systems!
Overall, if youre interested in upgrading your steering or suspension, dont think twice about upgrading with Kryptonite. As always, if you have any questions about what kit or component may be right for you and your truck, dont hesitate to contact us.

Missing half of the order
"The parts of it that I got look top notch. I am in not doubt that the rest will be just as good but I didn’t receive them"
Happy so far but not
"Happy so far but not loving the different feel. Seems quite a bit stiffer I can literally let go of the wheel and the truck keeps steering that direction. I called into tech support and was told that's a common complaint but it's because the design upgrade and it will get better with it. e so if that's actually true should work out to be great I'm hoping."
Suspension upgrades
"These upgrades made my truck drive like new!"
Revived
"2007. 5 Chevy Silverado Crew Cab 8' bed Duramax w/ 6' lift on 35x12. 5x17's Always rode well with weight behind her. But after almost 15 years, the front end was eating steering components. The Kryptonite ultimate font end package made everything better and back to how the truck used to ride."
Insane
"The warranty with these guys says go ahead try and break it. . . if u can we will replace it. . . their stuff is amazing"
Kryptonite
"Love high quality and kryptonite is high quality."
Q&A
- Does this kit come with a 3 or 4 master spline pitman arm?
- This kit is for the 3 Master spline applications. -Mark
- Will these work on a lowered/bagged truck? (PhatPhabz kit)
- The tie rods do not look to be compatible. I'm not familiar with that kit but did look at some pictures. Pitman arm, and the idler arm and pivot look like they will work but not the center link and tie rods. -Sands
- How much is the kit without the tie rod ends I have already installed PPE stage 3 tie rod ends on my truck along with kryptonite ball joints in upper and lower A-frame and have installed cognitive upper a-frame on truck dual shock setup without the hoop wanting to install a 6-in rough country lift I know I might have to change my end links to a longer end link right now I have kryptonite 0 to 2-in
- Those tie rods in the Kryptonite kit must be used with their center link. The PPE Tie rods can't be used with the Kryptonite center link. You can bypass those and just get the Idler side package and pitman arm if you wanted. -Sands KRY-KRISP10 is the Idler side package at 522.49 KRY-KR6654 is for the pitman arm at 227.99
