Suspension Enhancement Kit Recommendation for 2024 GMC Sierra 2500 AT4X
Updated 09/02/2025 | Published 08/08/2025
Question:
Looking for SumoSpring recommendation for 2024 GMC 2500 L8T AT4X AEV with stock suspension. I tow a 10k travel trailer during the summer season but otherwise am typically running unloaded. Looking at the SSR-207-47 but concerned about fitment based on the factory lift for AT4X. Would I need some sort of spacer to run this part effectively or would there be a better part to go with?

Hey Ty, I actually have a different system that I would recommend highly with the Roadactive kit part # RAS3611-HD which is a confirmed fit for your 2024 GMC 2500 L8T AT4X AEV. Unlike all other options this comes with everything you'd want from a suspension enhancement kit without any downsides. You get the easily adjustable suspension support but also improved ride quality and handling loaded and unloaded. Plus no maintenance like air bag kits require.
The kit you mentioned would also fit.
