The blocks with the stock leaves are just way too stiff, it hurts my back and my gf hates it. I want to get 5 inch lift leaves so the ride is softer and I have more flex for off-road. Ive heard of Old Man Emus and Alcan springs, but cannot find them online for my truck at that height. Maybe even an alternative to soften and have more flex? Do 3 inch springs and 3 inch blocks help considerably? Please Help!
