If you like the ride in back, but want some lift, without a lot of heartache later, go with a shackle in back. It will actually DO something positive, without warping your stock spring pack like an add a leaf. Downey off road has a kit with shackles, and an extender for the exhaust pipe. As for the front, DON'T BE CHEAP!!!! A coilover kit will give you 2"-2-1/2" on a 4wd taco, without too much sacrifice. You'll clear all the tire you will need for a start, and the truck will at least handle well. There are so many front end setups now, it's hard to list them. But try camburg, fox, donahoe, sway a way, or king. These are top teir, will set you back between $700-950. Depending on size and spring. Downey makes a coilover which uses a bilstien shock, that is a little older style, but still rebuildable. I put the Downey unit on my truck, while waiting to get all the parts together for my build up, I want the whole front at once. The cost was a bit better than the sway away setup. For what it's worth, the ride is TONS better than stock. Some have complained they could break them, etc. I can promise you. Watch this boards' posts, and see what these guys in N.Cal and Colorado do to their trucks. ANYTHING can be broken!!! Read up, and save some money up. You're gonna need it!!
