Mine drives like new with 80 k on it...I'm smilin...

 

I thought all the '99s had a rectangular filter........................but the later '99 edition filter is quite a bit thicker I think

I believe that all the mods were not done on the same dates. My truck has a 3/99 date and is the old style with the square top u-bolts. Anyway Superlift thought it was the new style and I had to send the track bar bracket, pitman arm and u-bolts back for the right ones because it's not. Just a word for the wise for anyone who has one built (like mine) not before or after 3/99

My truck does in fact have the newer badges though. The powerstroke badge on the door and the "superduty" under the F-350.

There's quite a bit of confusion on this subject as far as I've seen. Dale at Tymar told me the under hood differences don't go by the 3/99 rule either.

 

RRMike, you are probably right and there is not an exact cut-off date. More than likely Ford did like a lot of manufacturers and planned on converting things over on or about 3/1/99, but had parts left over and/or ran out before that date. Hence the confusion as there are hybrid conversions throughout possibly February, March, and April with the bulk occurring in March like what Ford planned. Just a thought.

I feel for you RRMike. Thankfully for me mine is clear cut. Good luck to you with yours!!

 

Thanks Ronin but it's all been taken care of a while back when I lifted it. I guess it sounded in my post like I had just sent the parts back. It was 6 months ago or so. It all got sorted out ok.

 

Are there any underhood differences besides the air filter?

Mostly air filter and battery tray(s). I've heard that some of the early 99's had the wicked wheel but no one I've talked to has seen one in anything newer than a 97?? I think.

 

my early 99 v-10 has cone shaped k&n same as my 03 v-8

 

hello
i have noticed that there isn't any mentioned of the pre 3/99 psd models had a catalytic converter, and now i see the new 6.0L psd have them.
my 99 f-250 4x4 cc sb psd has a born on date of 3/99, i have had a lot of issues with the correct parts!

 

My early 99 had 4 inch blocks (late had 2 I believe)
Early 99 had a larger air box length wise. K&N had two different sizes for me to chose from.

 

December 98 is the early date everything past that is later

 

Wow, super old thread....

It isn't as cut and dry as simply stating a build date since different parts were changed at different times during the production run. Certain early style parts can be found on trucks with build dates as late as 5/99....

 

My f350 is early 99 (manf date of 9/98). I'm looking to put a ranch hand bumper/grill on it. Part number FBF 991 BLR - dealer not 'sure' it will fit and called ranch hand to check. Ranch hand would also not confirm fit for 99 early manf date models. Anyone with experience that can help please? Curious if the body style on front end varies at all in the early vs late model of 99's. Thank you!

 

Also IIRC the front unit bearing flange on early is 8mm. The later are 10MM thick.

 

Based on the response that you reported Ranch Hand provided to you, I would take my $2,000 and spend it on a company with better customer service.

If you have a 4x2, there is no difference between an "early 99" and a "late 99" that would effect the mounting of a grill guard or full front bumper replacement.

If you have a 4x4, there could potentially be a difference, but that difference is not discernable by the pathetically written, non-illustrated instructions from Ranch Hand, which state: "On 4x4 models, remove the first existing bolt on the side of the frame."

It remains unclear what Ranch Hand means by "remove the first existing bolt on the side of the frame" since there is no photo showing the bolt.

Does Ranch Hand mean the bolts on the deformable frame horn that the OE bumper brackets attach to?

Or does Ranch Hand mean the bolts in the web of the boxed section of the frame that holds the front leaf spring hangar in place?

If the latter, following the logic of the language used ("side of the frame" equates to frame web), then that "first bolt" also holds the front leaf spring hangar, and that is where a difference can exist between early 99 and late 99.

The initial production of the Super Duty in 1998 had CAST front leaf spring hangers for the 4x4s. The transition from cast hangars to stamped front leaf spring hangars was a running change that did not coincide with the various other changes in exterior trim, rear suspension blocks, and diesel engine changes of "late 99."

How this could effect a Ranch Hand installation is entirely up to how the built in brackets of the Ranch Hand are spaced apart.

The cast front spring hangars are thicker than the stamped front spring hangers. If the brackets of the Ranch Hand are spaced for the stamped hangars, they may or may not be able to be bent apart enough to fit over the cast hangars, depending on if the Ranch Hand brackets are laterally gusseted for stiffness, or how thick the material is (1/2" is harder to distend than 1/4").

However, Ranch Hand is the center of expertise for Ranch Hand products. If they don't have the courtesy to research their own product in exchange for your $2,000.00, then I would take that $2,000.00 to another domestic bumper replacement company who is willing to look in their design records and actually earn your money.
