Hotchkis leaf springs sagg brand-new

I'll be jammed up all morning in meetings, feel free to call after 2pm PST on the land line if you need my cell, e-mail me and I can make time. We can discuss in detail tomorrow, but I believe the issue lies in the Dana 60 and your transmission yoke height. And all of our test vehicles are running off the shelf springs and have anywhere from 10000-60000 miles with them and the lowest powered vehicle is the Challenger at 307rwhp. The Road Runner's 383, the Taxi's 451, Sally's 440 and the Valiants's S/C 360 all put out north of 400hp and 400ft/lb of torque. 2 autos, 3 are 5 speeds. All 5 speeds are dual friction clutches and I would bet that they all get launched and driven harder than anything most folks put their cars through. The locker in the Road Runner is so tight, it tears motor mounts in half quite frequently and bucks the driveline on any turn below 15mph that isn't under power. I think that your springs worked as advertised and wrapped after repeated loading/bottoming of the suspension, however, benefit of the doubt ALWAYS goes to the customer unless we can find something wrong. Look forward to talking with you soon.
