I could use some wise advice. F150 SRW 4WD w/ trailer package. Mated with NorthStar Adventurer 8.5. Despite assurances from both car & TC dealers - fair amount of sag & sway. While many may say I ...
I found this regarding the HD Payload package too:
F150 HD Package - high capacity wheels - LT tires - HD shocks - upgraded rear axle: 9.75" gear set (instead of 8.80") - upgraded springs - upgraded radiator and aux. transmission oil cooler - stronger frame on all but screw (0.150 instead of 0.110 rail thickness). Screw has 0.150 rail thickness regardless of HD payload package already.
