hey whats up just purchased a 2005 f150 5.4 xlt here are some pix





i am new to the f150 but not new to the f series line coming from previously having 4 super duties in the past 10 years. 1999 f250 5.4 supercab 2001 f250 lariat 7.3 powerstroke, 2003 xlt f350 7.3 and my pride and joy a 2006 lariat f250 6.0

here are a couple of questions for the veterans...

i usually have to carry heavy payloads being in the paver industry and have to tow a bobcat on a trailer. what is the best upgrade i can do to the rear in order to hold more weight without bottoming out the truck?

also i want to add an aux input having noticed that the stock radio has an aux button. i have checked out the parts on installer.com and want to know which cable i should buy so i can use the stock radio to run an aux input..

any help is greatly appreciated...

 

A set of air shocks on the rear for leveling out heavy tongue weights.

 

And extra leaf springs for the heavier load. Also make sure you have a tranny cooler

 

are they pricey?

 

this^^ are there any threads or how to's on the matter? how can i figure out if i have a tranny cooler? do they come stock with a 5.4 xlt trailer package?

 

Easiest way is the PIE FRD04-AUX ~$80
Depends, you can get them for a couple hundred if you fore go on board air and just air them up with a portable compressor.

 

any particular brand that is proven? thanks for ur help gator!

 

has anyone had any experience with these?
