Chevrolet & GMC
IHC’s control arms for Chevy and GMC trucks from 1963 up to the present use a mix of Moog-standard ball joints. Make sure to verify your arm type (cast, stamped steel, aluminum) before ordering.
Key Notes:
– 2014–2018 trucks with aluminum or stamped steel arms require an IHC machined sleeve.
– Camber correction UCAs take specific part numbers like K6540 or K6696.
Ford
From 2015 up, IHC’s Ford drop arms stick with K6292 for upper and K6541 for lowers, with optional camber correction joints for better alignment.
Need to order a sleeve?
– 2021 and newer trucks require IHC-2021F-CON sleeve for the lower ball joint.
Ram
Ram trucks from 2009 to 2021 are straightforward with standard upper and lower ball joint fitment. The only major variation is the sway bar link based on 2WD vs 4WD configurations.
What NOT to Do
– Do not mix OEM ball joints with IHC-specific sleeves unless verified for fitment.
– Do not reuse worn hardware. Always torque new joints to spec.
– Do not attempt press-ins without the correct tools. Damage to custom arms may void your warranty.
