2000 4x2 XLT XtraCab wants to haul more and not sag. Helpers, Air Bags, or replace stock shocks? Leaving on the 19th and need to hussle!

I've installed a fiberglass cap, will have a loaded 4 bike trailer hitch rack, and a bed full of gear. I know I should upgrade but need solid advice and specifics as what to buy and not break the bank. DIY installation preferred. Thanks in advance folks.

 

Have you considered AAL (add a leaf)?

 

Are "add a leaf" the same as "helper springs"?

I'm looking at these...

Ford Ranger Helper Springs 1998-2009 - Hellwig # 1516 - LP-15 Series

 

looks like a good set up. Im considering the cheeper kit to help level out the truck. rear springs are getting a little weak. its supposed to be good for 550 lbs extra weight. Afraid the 1500lb set up would kill me on the dirt roads here at home.

 

Any of the things you listed will help level the truck when loaded but be clear on one important thing, none of them will increase your trucks payload capacity. Your trucks safe payload rating is calculated by Ford taking wheelbase, rear axle, engine, tranny, frame strength, gearing, braking ability, wheels/ tires, vehicle weight ect ect into consideration, not just spring rate. If your trucks payload is say 1000 pounds (you must subtract a full tank of fuel and passengers from that number too) it will still be 1000 pounds even after installing one of those load helpers. (air bags, AAL, helper springs ect)
