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

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.

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.

Be careful
"After buying the kryptonite ultimate front end kit and upper control arm with the ball joints for my 2016 3500 HD and having it professionally installed completely changed the way the truck drives and handles. But with that being the parts have 500 miles on them! Put my truck in reverse and backed up about 6 inches and stopped. Got out to look to see what was going on and this is what I had discovered. (Pic's below) What would have happened if I would have been driving down the highway at 75 mph pulling my 18ft gooseneck trailer?? You can see how porous the metal was in the picture."
Great products as always from Kryptonite
"This kit got my Chevy to quit doing its best impression of a 2nd gen Dodge. The truck drives better than new."
Don't buy it for Diesel Power
"They don't stock them all. Took them a week to tell me they didn't have it in stock and that it would take 12 weeks to get it. Canceled the order and still had to wait awhile to get a credit back. Go and order it on Amazon and get it in two days!"
2011 GMC Sierra 2500HD
"Worth every penny! I worked over my entire front end with kryptonite top to bottom and will never go with stock replacement steering/suspension again. Installation was relatively easy, instructions were concise, and the shipping was fast."
Well worth the investment. Truck
"Well worth the investment. Truck drives better than new!"
Huge upgrade!
"Definitely a very beefy upgrade, well worth the upgrade and will hopefully last a long time."
Works great everything fit good
"Works great everything fit good no problems so far."
Much needed upgrade
"Just got it installed in my GMC 2500 and that baby rides smooth I recommend to get this with the leveling kit save yourself the headache in the future"
L5P should’ve came with this from the factory!!
"It’s actually quite ridiculous how huge of a difference this kit made on the steering and overall handling on my 2017 L5P, especially when towing. Had it thrown on around 94k miles, and at the time of this review, truck’s sitting at 115k miles. I should’ve bought this way sooner instead of putting myself through such pain and suffering with the stock setup. In summary, if you’re struggling in the darkness with that loose OEM GM steering, this ultimate front end kit is the light at the end of the tunnel; it bulletproof’s the front end. If you tow heavy, you’ll no longer have to fight the truck to maintain control. You can tow up to max capacity with confidence. If you’re off-roading, you won’t have to worry about very easily snapping tie rods. Overall, GM should be ashamed for letting their trucks roll off the assembly line with such light duty stock/OEM components. These HD trucks deserve better, especially the Duramax ones because they tow heavier. It’s an expensive upfront investment that’s not just for looks and bragging rights; it’s about safety. If you got some time, take a minute to read a more detailed explanation below. I struggled for the longest time when the truck developed the infamous/dreaded loose GM steering. Quite honestly, the truck never had that “firm” steering from the very beginning. The stock setup and feel was alright when empty, but whatever when towing. There were times I wouldn’t even tow heavy with this truck because of that unacceptable steering. Driving a Ram HD, SuperDuty, and/or a semi truck would make me hate that GM steering so much, it wasn’t even funny. I asked myself how those fools at GM even allowed, and still continue to allow, such a car-like setup for a truck that can weigh upwards to 8-9k pounds alone… My truck’s even got the Z71 “off-road” package which is honestly a joke. A couple of badges and skid plates doesn’t justify the off-road part. How do you expect someone to willingly take their heavy diesel off-roading with pencil thin stock tie rods, or a weak front end for that matter?? The people who don’t know $h!+ about $h!+ would, but not those who know to surrender before being badly humiliated/defeated. I’ve seen too many videos of the stock tie rods bending or completely snapping in half when off-roaring or doing a 4WD boosted launch. Anyways, enough rambling about all that. But wait… I HAD TO SPEND UPWARDS TO $2,000 TO FIX SOMEONE ELSE’S (GM’s) STUPIDITY. I know they’re probably going for that smooth car-like handling and ride quality for the front end, but this kit still maintains that, if not makes it better… Alright, I’m done now. If you’re thinking about buying individual pieces of this kit, I wouldn’t waste my money by pairing aftermarket heavy duty components with ones that are light duty; cross contamination. You’re gonna have everything apart anyway, might as well. Save your money and buy this kit that comes with everything. I know guys that did individual parts (just the idler and pitman arm, or just the tie rods) and they’re regretting not buying this kit, so save yourself the buyer’s remorse. I even went a step further and replaced the stock gearbox with a Red Head (SKU #: RH-2875) because I didn't want to take any chances. Having said that, during the years of 2016-2017, these HDs were notorious for developing play in the gearbox itself, so. . . My truck also got the Kryptonite stage 3 leveling kit installed at the same time, and I tell you what, there was no negative difference in handling or ride quality. If you plan on leveling or lifting your truck, this kit is a must. Don’t spend all that time and money on raising your center of gravity without strengthening its “base”. Seen too many guys go that route, and then they’re fighting for their life to maintain control, especially the Duramax guys. You can’t beat the quality and customer service provided by Kryptonite. They stand behind their products, thus offering such a great warranty."
Q&A
- I know welding the gusset to frame is more strength. I do really light slow off roading more a dirt road if at all I am mainly on the highway some city and I do tow a camper and cargo trailer from time to time. is it a must to weld the gusset to the frame or is it fine just bolting it to frame. my engine is all stock and airbags in the rear.
- Just bolting it to the frame will suffice in your situation, welding it in would be for more extreme use.
- Will this kit work with the SUSPENSION MAXX 3" CONTROL ARM and TORSION KEY KIT
- Yes, those kits will work together.
- would this front end kit work with a stock front end with a cognito 4’ and T keys on max ?
- This Kit will not function properly with older style "Drop Centerlink" Lift kits. Or "Drop Control Arm" Lifts kits. Give us a call and we can get you going. 888-993-4373 Mon-Fri 6-6 pst. Thank you.
- Will this fit on a 2020 Sierra 2500 with a Rough Country 5 inch lift?
- 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 Kit will not function properly with older style "Drop Centerlink" Lift kits. Or "Drop Control Arm" Lifts kits. Please feel free to give us a call 888-993-4373 and we can help you find a set-up that works with your rig.
- Will this kit work with a procomp 5.5 in lift
- More than likely not. Due to the size of the tie rods Kryptonite does have a special kit for Fabtech and other aftermarket lifts. It is recommended to reach out to Kryptonite to ensure your lift will work with this kit. -Mark
