Rear Suspension Enhancement Recommendation for 2021 Nissan Armada

Question:

Hi. 21 Armada with factory air leveling. Wondering what’s available for rear suspension to improve towing and prevent sag. On my older Armada I installed different bump stops but I don’t see them for my ‘21. Thanks!

Hey Mike, for your 2021 Nissan Armada we have the Firestone air bag kit part # F4150 that is a confirmed fit and would work great to give your rear suspension additional support but we do not have any bump stop style suspension kits that fit. Air bags offer a lot more adjustability over bump stop style support systems so you'll be able to tailor exactly how much support you want. Did you have Timbrens in the past?
