When I put my truck together I ramped it about a year later. It pulled a 752 on a 25deg ramp. Limiting factor being Shocks on droop and bumps stops on compression. This year I ADDED two leaves in the rear to stiffen it up because it was too soft in the rear. I Put in 1 inch Zero rates on both ends. SAME shocks that have been on the truck since I put the truck together before the first ramping. Truck gained 3 inches suspension hight in rear and 1 in the front. By all my figguring if anything my RTI should have gone DOWN. Ramped it on exactly the same ramp at 25 degrees as the first time........839.63 /forums/images/graemlins/confused.gif HOW did I GAIN 87 points when I made the truck have stiffer rear suspension and did not change the shocks?!?!?!?!?!?! I rolled around under the truck looking and I cant' figure out how I managed that much better. Granted the front springs had more time to break in but I added a lot of spring rate to the rear set and it should have more than offset that.
