## Questions & Answers

**Q: Are these just heavy duty stock replacement parts or are they meant for a lifted vehicle?**
A: Definitely for a lifted vehicle. I gained a lot of downward travel by putting these on my truck. The original arms were resting on my droop stops. These arms increase caster angle and make the truck handle better too!

**Q: Does it come with ball joints?**
A: Yes upper ball joints.

**Q: Do they help with camber and caster angels?**
A: Yes! Kryptonite builds them with a few extra degrees of caster, to improve the ride. When getting an alignment, be sure to tell the technician to make the caster angles match each other INSTEAD of the factory specs.

**Q: How bad would it be if I installed these on a 2500?**
A: Kryptonite has a set of arms that fit a 2500. Use those. Dont try to mix 1500 parts with 2500 frames unless you already know they’re compatible.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Strong control arms
*by S***D on March 4, 2025*

Beefy

### ⭐⭐⭐⭐⭐ Fixes Ball Joint Angle
*by J***. on November 25, 2022*

I have 2006 GMC Sierra with a 6 inch rough country lift. The first picture is before I upgraded my front end. The ball joint and cv angles were pretty extreme. Plus, the tie rods idler arm, and pittman arm wore out pre maturely. The next picture is after all the upgrades. I installed the kryptonite upper control arms, kryptonite lower ball joints, kryptonite death grip tie rods, kryptonite sway bar links, a kryptonite pittman arm, a moog HD idler arm, a rough country steering stabilizer, and 07-18 front axles. I also added cognito’s PISK bracket just too the moog idler, because the other bracket didn’t fit on the kryptonite pittman arm. This fixed the ball joint and cv angles, the steering feels tighter, and the truck rides better. I would recommend these control arms to anybody with a lift that wants to improve their ball joint angle.

### ⭐⭐⭐⭐⭐ Perfect
*by C***Y on June 21, 2024*

Fit perfect even with my AFP coilover kit. With a 6in lift the ball joint sits at perfectly striaght angle. Better than I could have thought.
