Question:
For the Firestone Coil-Rite Air Helper Springs F4155, Do you know if these will work on a 2024 Toyota Sienna with RSR Down-sus lowering springs? I plan to lower my Sienna, but Id like to maintain level when loaded with passengers. Thanks!

Hey Peter, so we have suspension enhancement that fits your 2024 Toyota Sienna with the Coil SumoSprings part # CSS-1168R but the Firestone Coil Rite you mentioned is not a fit and there isn't a similar kit that does. It's hard to say though if the SumoSprings kit fits lowered springs though but it would be best chance of working.

Hey Peter, did you end up trying the Coil SumoSprings on your lowered Sienna? It’d be great to hear if they helped keep things level with passengers on board. Your update could make it easier for others lowering their vans too.
