These are stock springs and that's how they are stock. They're rated for 1400lbs each. Those springs jad negative arch with no engine in them. You can kind of see it n this pic. That's the only pic I seem to have showing it.

On my Crew with the cummins it originally had a 350 I measured the frame to the floor with the 350 in, then no motor, and the cummins in and there was less than 1inch difference in all 3 measurements and about a 1/4in between the 350 and the cummins it was about 400 lb different by the specs so that less weight than me and one of my buddies sitting in the front seat. I am going to put new springs on but mine the bushing are completely shot
