Published 04/10/2024

Question:

I am towing a 3550lbs trailer with a hitch weight of 425 lbs with a 2023 Toyota Higllander Limited Platinium. I would like to install these Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle Item CSS-1145R on the rear axle . Does this part CSS-1145R fit my vehicle? Can installing this part affect or be problematic for Toyotas warranty?

Yes, the Coil SumoSprings Custom Helper Springs # CSS-1145R are confirmed to fit your 2023 Toyota Highlander Limited Platinum. You should not have any issues for your warranty as it is a add on part and you are not modifying the vehicle components. You are simply helping to provide support to the rear coil springs. The only way you would void your warranty is if Toyota could prove the parts caused a failure or you tried to overload the capacities given from Toyota.
