Question:

I’m looking for a helper Springs for my 2025 Chevy Tahoe Z71 with independent rear suspension. I’m not seeing anything on your site. Do you have a product or can you help me out with this?

Hi Jeff; there are no custom fit options for your 2025 Chevy Tahoe Z71. However, you may be able to use Coil SumoSprings like the # CSS-1195 you were looking at.

Measure your coil spring gap as seen in the attached photo. Take the measurement with the vehicle as it sits. You do not need to raise it. Once you have this measurement you can add it in the comments below and I can see if there is an option that will fit.

Hi Robin, The measurement is 2 1/4” I took some pictures, but I can’t upload them to this message that I’m sending to you. Appreciate the help! Jeff

@JeffO thanks for the measurement. Unfortunately, the # CSS-1225 is the largest and it fits gaps that are 1.9375” – 2.1875” so you're just a little outside that range.
