Hey Bryan! You can use the RoadActive Suspension Custom Leaf Spring Enhancement Kit with your 2025 Sierra 2500 Denali Ultimate. However, I believe the max trailering package comes with the top overload springs. I would verify this just to be sure. Assuming that is correct, you need the # RAS3611-CHD.

Are you adding these for towing, hauling, or something else?

RAS will fit that truck, but only if you do not have overload springs. These overload springs are positioned where the RAS mounts. So if your truck has these springs, it is impossible to mount the RAS.

@Bret the version linked above # RAS3611-CHD actually comes with an additional steel plate for overload spring compatibility.

@RobinH I’ve had some confusion about this. With the model you mentioned, does it allow me to leave my top overload springs in place and install the RAS as well? I have a 2026 3500HD AT4 with max trailering. Thank you!

@Rick it does not remain in place. The RAS # RAS3611-CHD will take the place of the top overload springs. Take a look at the instructions linked below.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…
