Full Race's "Gen 2.5" Raptor build

[mashtastic]

The b&m 8.8 is quite deep. It’s was originally designed for the rear diffs. I tried to fit the ford performance on an 2006 f150 Harley edition but didn’t have the clearance with the steering rack… and there was more room than the raptor. I have the Spicer on the ‘17 raptor and modified the stock cover with a drain plug on my ‘14.
B&m 9.75 is money, have that on both trucks but might not play well with a 37” under the bed

Thanks for the input! with the Gen 3 rear suspension it’s the panhard bar that would hit the diff as opposed to the 37” spare tire. Worst case Ill grind, weld, or scrap if it gets to that point

The new 2023+ navigator/expedition/platinum f150 have no IWE. It appears they use a traditional FWD style hub and axle splined interface.



The OD is now smooth and absent of the splines for the IWE. Instead the ID is now splined



Now THAT is an iwe delete. Unfortunately I expect the bolt pattern will not work for my Gen 3 uprights.

Thanks Geoff for the awesome thread! I recently pulled the trigger on the ATI balancer mentioned earlier in the thread and figured I would try to add some value here. Attached are a few photos; one of the finished install and I also attached the part numbers for the belts that are required to run it. The ATI balancer is 4% overdriven from stock so I had to play with a few different belt sizes. I also discovered that if your Gen 2 3.5 has 112,000 miles like mine, the overdriven pulley makes the old accessories less than happy. I ended up replacing the water pump, decoupler pulley, idler pulley and tensioner with new Motorcraft parts. Also, another side note; on the Gen 2 stuff the crank isn’t keyed but the ATI balancer is. I was instructed by ATI to just throw a small dab of RTV in the empty keyway to prevent an oil leak. I hope this helps some of you guys looking to do the swap!

Also for Geoff,

After install I noticed a more pronounced hollow sounding knock coming from the engine at low RPM. Only happens in drive and only on very low speed light throttle. Part of me wants to says it is direct injection noise. With your experience with this balancer, did you notice anything like this? Also, any idea if ARP makes a crank bolt that will fit this engine? Is it the same size as the coyote bolt?

Thanks guys!

I also just bought the ATI balancer. Did you have a keyway machined into your crank? My engine is apart and the machine shop says they can’t do it. I didn’t know if I needed to take it somewhere else.

yeah but what axles are we expecting to use? Raptor axles engage with the IWE, not like this one does..
