Bear Lake Cruiser
SILVER Star
I have had good luck reaching and lasting a decent time. I do not wheel the crap out of my rigs on a regular basis and flex the springs hard, just the odd weekends. Maybe that is why they last long. I always tell them to add a bit more to the measured arch I want so it is close to where it needs to be once installed and loaded. Many larger towns will have a specialized spring shop that can hot and cold form.
