These front 3", 4", and 5" springs are now available in a heavy-duty version with a 25% higher spring rate. The HD leaf springs are great for heavier trucks and 4Runners with full bodies and exo-cages, V6 Toyota and Tacoma applications, and also works great for V6 and V8 engine swaps. The length is the same as our super flex spring, but with a higher spring rate the spring will hold its arch and lift longer.
