Is There Difference Between 2WD and 4WD models 2019 4Runner for SumoSprings
Updated 12/08/2025 | Published 11/25/2025
Question:
I have a 2019 4Runner TRB Offroad premium. I will be towing occasionally a camper with 450lbs hitch weight. I will be getting a weight balancing hitch but I also looked at the sumosprings. I am not sure what the 2-wheel and 4-wheel choices are for. Does it refer to the mode I will be driving the vehicle?

Hey John, so the 4 wheel drive and 2 wheel drive versions of your 2019 Toyota 4Runner have some differences between the rear suspension which is why in our fitguide we have the two style called out and have the correct fits listed for either. But the good news is that SumoSprings has the same fit part # SS78DR for both the 2WD and the 4WD models so this would be correct fit for your TRB which is most likely a 4WD.

Hey John, how did things go with the SumoSprings on your 4Runner when towing your camper? It’d be great to hear if they helped level the ride and improve handling. Your feedback could really help others setting up a similar tow rig.
