The issue with any leveling method is the UCA balljoint angle of the OEM balljoint. When I installed my king shocks, I also installed Cognito UCA s with larger ball joints.

you saying even with a 2" front level its a issue for the ball joints?

Just got my RC 2.5 leveling kit installed today . Also installed 295/70x17 nitto trail grapplers m/t on 17x9 xd addicts. Was too late to take good pictures. Will post tomorrow

Looks amazing. You're definitely making my wheel/tire decision hard. If I end up getting aftermarket wheels, I'm going with your size.

 

Any rub?

I love the look of small wheels and all that rubber! What offset on the wheels? Nice lookin truck!

No rub at all offset is +18 . Full lock and reverse seem to be great so far did some driving tonite , zero issues which im happy about.

That seems to be the history from the GMT900 which shares the same components and geometry. It's not the 2" of lift, it's the 2" additional downward full extension. This apparently bangs the ball joint against the limit of its travel and evidently damages and shortens the life. Many of the GMT900 guys had premature upper ball joint wear-outs with 2" levels. The OEM UCA ball joint is a very small ball.

 

Aftermarket UCAs have the ball joint installed at an angle to accommodate further extension (down travel).

No, That one will work, but it's an unprotected Teflon socket on a steel ball that the racers use. My truck isn't a race truck. I don't want to maintain it like one either. I bought their, UCA with a regular automotive ball joint, albeit a heavier ball joint than the OEM.

Aftermarket shocks/struts would do this too would they not?

Shocks like the Kings and Fox may have longer extension than stock. Frankly, I didn't measure my Kings against the OEM Ranchos for full extended free length when they were out of the truck. I installed the Cognito UCAs because I knew that GMT900 trucks needed them with the King shocks and these trucks use the same suspension.

 

Anyone using spacers like the RC kit, might benefit from an aftermarket UCA with the adjusted ball joint angle. I just don't sign up to the idea a dry Teflon socket with a steel ball, exposed to the dirt and elements, is going to last very long. I hear they also develop a squeak.

 

For anyone contemplating an aftermarket UCA, forget about the cheapest one on the market @ $250, the Rough Country UCA. It is designed poorly and interferes with the frame fittings. No amount of grinding on the frame as they recommend, allows for complete factory camber/caster adjustment range.

I would think a preloaded shock/strut like the 5100 bilsteins or rancho quicklift wouldn't require new UCAs. Still the same length or almost as OEM but no limit on upward travel if the shock is there to compensate for the decreased length of compression due to the preload used to raise the truck. That and it doesn't over extend downward travel. Or at least that's what i'm getting from reading this.

I think the Bilstein does protect from over extension. Dont know about the Rancho.. But I wouldn't consider the Rancho. I dont like their valving nor quality.

I haven't found it in writing but, i'm pretty sure bilstein compensates for the reduced spring travel with their shock, though i could be wrong. I don't mind my ranchos on my truck but i've yet to read negatives on bilstein and they seem to a great reputation. So i'll be tying to hold out for 5100 ride height adjustables for the 2014s, if it takes too long i'll be looking for coil overs.

Hold out for the Bilsteins. When you get the Bilsteins installed, you'll know why so many people recommend them over a Rancho.

Rancho quicklift loaded front. Just got everything installed about two hours ago. Right now I can only give u a review on how it drives compared to the rc2" leveling kit and I must say drives so great it's unreal. I have gone over the same bumps in the road I did with the rc kit and u can't even feel them now. So stable and no bouncing it's wonderful. Remember also had rs9000xl put in the rear. Plus I must say it looks better also. Front now looks a little higher then before. I will post more updates tomorrow night after I pull my trailer all day and post pics. So far [emoji106][emoji106][emoji106][emoji106]

    • Hmm. A real reason to not just use the odometer to determine OCI?    
    • Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir. 
    • I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.
    • I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed. 
    • Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.
