I need about 12" lift for the rear on a 96 tacoma. I already have a 3" bodylift. I want approximately 9 - 12 more inches. How many options do I have with springs. I have seen alot of 63" chevy springs out there. Whats up with those. Are there any other springs recommended for that amount of lift? The way I understand, you can use almost any spring. I know it sounds crazy.
