Which Timbren Rear Suspension Enhancement Kit for 2022 Toyota Tundra

Updated 01/27/2026 | Published 08/23/2024

Question:

I can’t decide on which one to get. I tow my 3500lb boat from time to time and occasionally throw some lumber in the bed and my truck squats a bit more than I like. I know I don’t need the severe, but I can’t decide between the other two. Is there a big difference in ride quality between the two? Is the gap between the rubber and the axle any different between the two or is it just the stiffness of the rubber? Thanks.

Hey Matt, so you would definitely want to go with the standard capacity Timbren kit part # T45MR that fits your 2022 Toyota Tundra over the severe service. The severe option is for trucks that will always have a heavy load in the bed like a camper or always towing a trailer. For your application it would be WAY to harsh and you'd hate driving the truck. The standard duty will be a much better blend of ride quality and support.

Hey Matt, how did the standard Timbren kit work out on your Tundra when towing your boat or hauling lumber? Your feedback could really help others trying to balance ride comfort and load support.
