checking my emails now, i'll look for yours.

 

I sent you another email the same way as I did before. I just have a quick question about which of the three to put in my cart. It probably doesn't matter as long as I order 8L3Z5310Z. I just want to make sure I do it right. Please let me know so I can create an account and place my order. Thank You Very Much!

 

doesn't matter just listed in the different catalogs.

The front coil springs part number 8L3Z5310Z (have the number memorized now lol) are on order. I am anxious to get them. I am going to try and take pics and post here of before, during and after install. My 04 only has 7000 miles on it so the underneath is still just like new without any rust. I have never driven it in the salt. This might help everything loosen up a little easier.
After I get the snow plow I want to get the biggest set of tires that will fit on the stock 18" rims. Does anyone happen to know what size that would be? Thanks Again for all of your help.

 

Hello, I have a brand new pair of Front Heavy Duty Coil Springs part number 8L3Z5310Z that I am not going to be using. If anyone is interested in them, let me know. Thanks

 

I just PM you!.....

 

RISUPERCREWMAN,
I tried to send you a message. I not sure it went. Please let me know if you got it. Thanks!

 

Sent you a PM!.............

 

Did you guys make a deal?

 

He lives next door to a wholesale dealer so without shipping charges he can get a good deal there. The new never installed Heavy Duty Front Coil Springs part number 8L3Z5310Z are still available. Anyone interested? Thanks!

 

I see this is a really old thread, but I know a lot of people still ask this question and there is a lot of misinformation in this thread.

The front springs are NOT the only difference with the 8200lb GVWR F150 with snow plow prep. Here are the actual differences.
1. The frame itself is made of thicker guage steel.
2. Heavy duty hubs with seven lug rather than six lug.
3. Larger front and rear differentials are larger diameter
- This translates to heavy duty ring and pinion
4. Higher capacity front and rear springs

The heavy duty springs will help the truck hold the plow, but they are actually the least significant difference pertaining to plowing snow. The snow plow prep package includes major structural upgrades.


FYI. Anyone wanting a VIN to check the heavy snow plow prep part numbers can simply go to fordvehicles.com and search dealer inventory for a vehicle with snow plow prep. They list the VIN numbers on the site.

 

Did you not read page two of this thread, to Whit:

Lots of stuff different on the '04-08 F-150HD-

Chassis: 5.6 cu-in. section modulus/.150 wall thickness. The rest of the trucks (except the 144" WB) had 5.25-cu-in/.136 wall frame rails.

Springs (& shocks): 4050# front vs 3450#, 4900# rear vs 3850#.

Rear axle: 5300 GAW RATED 10.25 SF vs 9.75 (4200#) or 8.8 (3800#)

Gear ratios (4.10:1),

Those wonderful 7-lug wheels

Load Range D-tires

Plus they have a particular combination of things you could get on other trucks as options, including the 36 gallon fuel tank, 9-row trans cooler, trailer hitch & wiring, bigger battery, HD cooling (1.42" core/15.24 FPI vs 1.02"/13.93 FPI).

They only came in XL or XLT trim.

My factory data books say the HD was the "required" base setup for snowplow applications.To which you added the "Snowplow Prep Package," which included 4300 pound front springs (the part number I gave are for the 4050# springs), even higher rated than the regular Payload Package springs.

Ruckus: Besides the seven-lug wheels, all you need to look for is a "V" in the fourth place on the vin code. That indicates a 8200# GVW truck.
It took me nearly two years to find mine used, and in the end I got one direct from Ford's pool fleet out of Dearborn.

I was told by a Ford engineer that the payload packages averaged out to only about 3 percent of production and that most went to government or commercial fleets. Last year, I saw a bunch of them with a U.S. Forest Service group that was doing some kind of a shoreline survey on Lake Erie. I think I counted 11 of them

 

I must have skipped from page 1 to 3. I didn't see that one at all. Snow plow prep required(and still does) HD load package for the supercab. The regular cab could actually have snow plow prep without the HD load package. The snow plow prep is the only by the book way on the warranty issue, but most dealers won't say anything unless they feel a vehicle has been abused or used commercially. A few are sticklers, but not many.

 

Rukus, what happened, after all this you are not going to use the springs?

 

You could use #81120 Moog springs but they are a little higher than the OEM numbers. It may be less if you have to pay to ship them though. Orielly's and Advance have them for about $130 for the pair.
