EB now available on build & price. Also 4.10s now an option with EB on FX4/max tow/20s as discussed.

 

EB option doesnt really change the price but the question still remains will it last in a truck?

 

I would take a look at the Torture Test, at fordvehicles.com. I think they put one particular EB engine through more stress than any owner could hope to.

I wish I had waited on replacing my '04 a couple more years. I love my '09, but, these '11's are looking to be the best yet out of Ford!

 

This threw a money wrench into my plans. I am sure on a EB Platinum SCrew but

The 3.73 LS adds the Max Tow option for ~$500.

Trailer Tow Package (required for towing over 5,000 lbs.) includes Class IV trailer hitch receiver, 7-pin wiring harness, upgraded radiator, auxiliary transmission oil cooler, and SelectShift AutomaticTM transmission (9,700 trailer weight)

Max. Trailer Tow Package (Regular Cab and SuperCab; restrictions apply; required for towing over 5,000 lbs.) includes Class IV trailer hitch receiver, 7-pin wiring harness, upgraded radiator, auxiliary transmission oil cooler, trailer brake controller, upgraded rear bumper, SelectShift Automatic transmission, and manual telescoping/folding trailer tow mirrors with manual glass or manual telescoping/folding trailer tow mirrors with power/heated glass, integrated turn signal indicators and security approach lamps (11,300 trailer weight)

For the Platinum the only addition is the tow mirrors which I do not want. I would rather have the power folding ones. I'm not too worried about the extra 1,300 trailer weight, I have friends with F250s if something gets that heavy. How much would I lose going with the 3.55Ls over the 3.73s?

 

How much of what would you lose?

 

Hard to say given none of us have driven them back to back with diff rear ends.

Think of it this way, wit a 6 peed 3.55 is still very steep compared to older trucks with 4 speeds.

Heck my 98 4wd with the 235 hp 5.4L only had a 3.55 and thats with a 4 speed.

If your not maxing out on towing, you'll be fine.

 

Why wouldn't it?

 

I'm with wookie, kinda got a kink in the plans... I don't want the tow mirrors but they come with the max tow and I possibly want the 4.10 rear end but not for 1600 extra bucks..

I can tell myself all day I won't go crazy modding this truck like my current one, but I know I will... I tell myself nothing over 6" on this one but deep down know it will be another Rize...

Good to see the EB up on B&P finally. The fully loaded FX4 I priced with 4.10's came too right under 48k.

 

Mostly low end grunt, but are there other hardware differences that are not listed? I don't think so because the payload remains the same but someone on here might have some insider info.

PK, I'm pretty much in agreement with you. I've had 3.31s (2001 SCab) and 3.55 (2003 SCab) behind the old 5.4s but I still would rather have the 3.73s. I'm thinking the low end of the EB will really make it so that it doesn't matter.

 

Payload is not the same with max tow vs without. Max tow gets 300-400 pounds more payload, higher GVWR. 300 pounds at 15% tongue weight is at least 2000 pounds more usable trailering capacity, regardless of rating. It's a great value package for the mirrors, higher capacity springs, and brake controller. Sell/trade the mirrors if you don't want them.

As for the gearing, keep this in mind. The first 4 gears of the 6-spd with 3.55 axle ratio would be like all 4 gears of the 4-spd with a 5.30 axle ratio. I think it will do just fine.

 

According to the build and price on Ford.com the payload for a 4x4 EB 5.5 bed SCrew is 1,960 pounds with both the 3.55 and 3.73. The only change is the max trailer weight. The brake controller is standard on the Platinum and I can not find anything that shows upgraded springs. If you can I would appreciate it. Changing out the mirrors can be done but I would have to buy the powerfold mirrors which on my 05 are over $450 apiece! The Platinum mirrors are only shared with the KR so second hand options will be limited. I use the power folding mirrors and I would miss not having them.

The more I think about it 3.55 to 3.73 will give ~200 more RPMs in 6th gear. My 05 which has 3.73s and nearly the same top gear. It turns right around 2000-2100 RPMs at the highway. The EB motor starts making its power ~1700 RPMs. The 3.55s would barely be into the EB's powerband whereas the 3.73 would be past this by a little bit more stopping the engine from lugging or downshifting for small speed changes or hills. Most people pulling loads 10,000 or up in a F-150 will have a travel trailer hooked up and the mirrors will be needed too. It does make sense to put the two together. That's my guess for the reason behind this option combo.

 

Not quite. According to Ford, the EB is already making 375+ ft-lbs at 1,750 rpm. It reaches max (420) torque at only 2,500 rpm. Might as well be driving a small diesel!

Compare to the 5.0 requiring 4,250 rpm to reach it's max of 385 ft lbs!!!

Heck, even the mighty 6.2 requires 4,500 rpm to reach it's max of 434 ft. lbs!

Take a look at the dyno chart on this page. Notice how quickly the EB climbs and stays there?

 

Payload increase does require max tow.

Also affects gawr which is the real limiting factor.

 

You can't go by the build and price. Build and price gives accurate info hardly ever. Payload on non max tow 5.5' 4x4 supercrew is 1590, in max tow (3.73) it is 1960. This is the most it will be but once you add options of the Platinum it will be even less. GWVR with the non max tow will be 7200 and with max tow it is 450 lbs more, 7650.

 

Gotcha, I looked in a different spot on the Ford web site and ran across a chart there that shows the numbers you listed. The strange part on the build and price the weights drop when you go from the 5.5 bed to the 6.5 bed and 4x2 to 4x4 etc. I wonder why they make the numbers mostly correct except for that option.
