Looking for feedback of making susp more compliant, smoother riding.
If you're looking to ignore all the factors that actually make the largest difference, then by all means: http://red90.ca/rovers/springinfo.html
Look at the spring rate for your 90, then pick some springs with less rate. In my experience a softer coil of equal ride height results in a slightly less NVH but relatively more flex and body ro TV
With standard springs and revalved shocks, it’s a game changer. Replace your worn out bushings/ get rid of any poly bushings and keep it simple. What shocks do you want to run with the Alive springs, what tires are you running and their date codes? Rock hard older tires and worn bushings are true misery on these trucks. Have fun and post up what you end up doing! Enjoy.Never heard of the company you mention.
With the link to genuine springs above, you see spring rate, the load needed to compress the spring by an inch.
Go ask Alive for the comparable Eibach numbers.
