You can make your own HDPE top-out spacer. buy and HDPE sheet (12" x 12") sheet from mcmaster-carr or from other HDPE-ABS suppliers.. then cut it out..

on the aspect of tank empty vs. full...

let's say the difference is 15-gallons. gasoline is about 7#/gal. that's 105# of gas in the tank. it's approximately 65% to the rear of the truck. simple statics says that the rear axle would see about 68# of that weight. if it's 75% on the driver side, then the driver rear coil would see about 51# of weight from the full tank.

Weight dist:

DR = 51#
PR = 17#
DF = 27#
PF = 9#

the rear spring are approx 150#/inch for the spring rate, and the fronts are approx 400#/inch.

the deflection for a tank of gas are approx:

DR = .34"
PR = .11"
DF = .07"
PF = .02"

assumptions used, but you get the idea...


same goes for any weight added, including your butt and passengers...
