I have stock TRD suspension and I wanted to konow if there is any way to stiffen up the stock suspension? For example could I run a tundra V6 coil on a TRD bilstein shock (from a tacoma). Also, I have a question about the overload spring in the leaf pack. Could I remove the spring and replace it with 2 leafs from another pack and keep it at almost stock height. Just trying to think of ways to make my suspension beter FOR REALLY CHEAP (less than $150) before i go on a trip to glamis.
