Hi Ramon,

You are not alone in noticing that the 2024 Grand Highlander has a very soft rear suspension. If your main goal is reducing rear-end squat and helping the vehicle stay more level when loaded, a Coil SumoSpring solution may be a good option. However, I want to make sure we get you the correct fit before recommending a specific kit. The rear coil springs on the Grand Highlander are larger than what we typically see on many SUVs, so we'll need a few measurements from the springs to determine before I can determine if part # CSS-1069 or any SumoSpring Coil Spring will work for you.

I have attached the SumoSprings fitment guide below. You'll need to print the guide and cut it out so you can take the measurements required by SuperSprings. Once you have those measurements, send them over and I'll be happy to help determine which Coil SumoSpring will be the best fit for your Grand Highlander.

One other simple thing worth checking is tire pressure. Underinflated tires can sometimes contribute to a soft or floaty feeling, especially when carrying cargo, although they won't fully address suspension squat if that's the primary issue.

f you let me know what measurements you come up with, I can help further and determine which Coil SumoSpring will be the best fit for your Grand Highlander. Are you mostly dealing with squat? are you carrying a lot of cargo?
