Question:
I’m looking for Sumosprings or similar product from another brand to fit a 2025 Sienna Woodland Edition. I want to use a vertical bike rack and tow a light skiff and am concerned about bottoming, etc.

Hello Juan,
Congrats on the new ride! We have 2 options for suspension enhancement for your 2025 Toyota Sienna. The Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle # CSS-1168R, and the Firestone Coil-Rite Air Helper Springs - Rear Axle # F4155. I would personally go with the # F4155 for your situation. If you were just going to use it for the bike rack I would go with the # CSS-1168R, but since you are going to be towing a light skiff, having the adjustability will be a nice feature for you. If you are looing to add a light air compressor as well, I would go with the Air Lift Air Shock Controller Compressor System for Air Shock Absorbers - 160 psi # AL25804, for the wireless option with remote and bluetooth you will want # AL25980. I have included a couple of review videos so you can get a good feel for the products before purchasing.
Whatever option you choose, I just hope you catch some monsters out there on your Skiff!
Happy New Year, may 2025 be your best year yet! From, your friends here at etrailer!

Hey Juan, how did things go with the Firestone Coil-Rite springs on your Sienna when towing your skiff? Your update could make it easier for others setting up a similar load and bike rack combo.
