Kryptonite Upper Control Arm Kit For 2001-2010 Chevy GMC 2500HD 3500HD Pickup

I can't recall the last time if ever I have received any auto part that was as well packaged, comprehensively thought out and we'll documented as this. Quality from starter to finish and looks amazing. The install instructions are color, glossy, in english, printed on heavy stock that stands up to greasy hands and double sided single sheet for ease of use. No less thought was applied to any portion. The ball joints and bumpstops are quality pieces and easy to replace with parts that are readily available. The bushings are greasable poly with the zerk fittings. There's a place to attach the brake lines. The hardware is quality and all there and pre packaged. The. Packaging is high end with high density foam cut out to protect the parts. It was a pleasure to receive, open, and install.Pro tip, the flat sheet of foam on top of the parts was a great kneeling pad and place to lay when needed as well as a great place to set the new arms before installing. I had zero difficulty in installing them other than having one of the alignment pins loose which I had replacements on hand since this wasn't my first GM truck install and you want to be prepared for that. Also one of the pockets was slightly deformed which happens so don't be alarmed and be prepared if it fights you but this one only needed gentle persuasion but be prepared with a pry bar and hammer. Second tip the rear most camber bolt is easier to install with the arms just barely installed enough to see most of the bushing in the closest side of the slotted opening, a lady slipper or punch or I guess a screwdriver can be used on the inside to pry to get it lined up completely while pushing the bolt through with your other hand.

Was going through upper ball joints every 3 months. Over a year so far with no issues.

Perfect fit easy to install very well built

Night and day difference in steering, ride quality. Truck handles so much better. Went from stock to these awesome control arms. Built solid and bushings are super nice. Allowed extra camber to get truck aligned perfectly. Went on a 99 GMC 2500 with 6 inch lift and 37s. No issues at all. Easy to install. Thanks Kryptonite!

I knew I was going to put a leveling kit on my 2006 Silverado Dually, but trying to find the right company to go with is like opening pandoras box! After a lot of research, I kept stumbling upon Kryptonite products.Well I pulled the trigger on these control arms, death grip tie rods, end link extensions, and the leveling kit. They don't disappoint! Heck, even the way the box their products is incredible! After getting the truck an alignment, the thing seriously rides so smooth and feels tight.

100 times stronger than stock and well built!!!

Went together easy

Overall very pleased. Only reason not 5 stars was these have no place to mount line for wheel sensor. I had to improvise with zip ties. Also picture shows green boots on ball joints. They actually arrive in black. Overall easy installation. Take time read directions. If truck is lifted take to a shop familiar with alignment on lifted trucks! Drove only a few miles but so far everything feels good. I put these on a 2002 cvevy 2500hd, with 6" lift running 38" super swampers. These arms look much better than moog and look well made. Definitely will be noticeable on your vehicle because they are obviously not OEM style when anyone looks at it.
