Hello. We do have a rear sway bar that will fit your 2022 Ram 3500 Laramie mega cab short bed 6.4 Hemi 4x4, but the # HE24MR you mentioned will only fit Diesel models and is not compatible with the 6.4 Hemi.

Instead, what we recommend for your truck is the Roadmaster # RM73FR. This is compatible with both gas and Diesel models. Just keep in mind this is intended only for vehicles without a factory sway bar.

Hey, how did the Roadmaster rear sway bar work out on your Ram 3500 with the 6.4 Hemi? It’d be great to hear if it gave you the stability you were looking for. Your update could make it easier for others with the same setup.

@JesseM Worked great, but was a challenge to install in my compact garage.
