|thaduke2003||I still don't recommend adding engineering to a bad idea. Instead, leave that bit alone to serve its function (the tailgate), and find a better solution (a tire carrier mounted on the bumper)- Mark W.|

|thaduke2003||Still putting the weight and strain of the spare on the stock hinges. That's where about 2/3 of them break. Some crumple right in the middle, which a carrier like that MIGHT help, but I doubt it. Also, that looks like it holds the spare out a bit further than the stocker, which would only make things worse- Mark W.|

What about using one of these?
Tailgate Tire Carrier by Hanson Offroad and Other Jeep Parts and Jeep Accessories by 4 Wheel Drive Hardware-RH1
I am thinking of going with something like this when I upgrade to 35s. Anyone have any experience with this? It is less cost than a new bumper with a tire carrier.

I have had a 35 on my tailgate for 2 years. Hinges on gate are wallowing out. You need a carrier for sure. Mine is coming in a couple weeks
As for gears...... REGEAR, I am running Stock 3.73 in an Auto but not for long.......
Take the advice from most and do it proper before something breaks.

|thaduke2003||^ Physics is physics, regardless of terrain. Even taking into account over-engineering, at some point, you must understand that going 50% over what something is designed to take is a BAD idea, regardless of clever ideas and such. Metal shears, regardless of terrain. Yes, bouncing around off-road WILL take a toll much faster than on-road, but any over-stressed component WILL fail in time- better not to take the chance. $700 for a tire carrier is a WHOLE LOT cheaper than possibly hurting or killing someone due to negligence- Mark W.|

^ Exactly. In engineering, there's always a 25-50% extra over-engineering standard built into any contraption/design.
It's amazing what you can learn simply by reading the owner's manual Mark W.

According to my owner's manual:
If you have added aftermarket accessories to the
spare tire mounted carrier, it cannot exceed a gross
weight of 50 lbs (23 kg) including the weight of the spare

The gal who lives next door (my daughter) just bought a Shara Unlimited. It was immediately lifted and 35s installed. Auto and 3.73 gears. It doesn't like hills or a stiff headwind at all. They are trying to decide between a 4.10 or 4.88 regear since the gas mileage also dropped like a rock.
The tailgate will fail hauling a 35" tire around. How quickly depends on how rough the roads you drive are. I bought her stock wheels and tires and the tailgate is loaded with the 32" on it.

D30 front axle with 35s. Not a bad idea to sleeve and gusset the 30 and even a 44 front.
The early '07s did have D35 rears; I've only seen one though.

Hi everyone, new member and I already can't stop reading all of the great Q & A's. I have a 2010 JKU Sahara and I have put 35's on it. No regearing (yet?). What cost is associated with regearing to 5:13's? What RPM at highway speeds if I do?
My JKU has the Next Gen Dana 44 rear and Dana 30 front axle. For the 90% road and 10% off road (no rock crawling) am I going to see drivetrain issues in the future. Thanks everyone - GREAT Forum!!!!!

As for gearing, you have a Rubicon. The 4.10 gears are WORLDS apart from the X/Sahara 3.21's or 3.73's. While the numbers seem to be minorly different, in terms of physics, the numbers are huge, especially in the lower gears. As for being under-geared, you're putting a huge extra strain on your engine, transmission, clutch (if manual), and the rest of your driveline. There's a reason you choke down fuel when under-geared. Short-term, it only hurts your wallet via fuel bills. Long-term, plan on rebuilding the driveline MUCH sooner. That'll hurt a WHOLE lot more than re-gearing- Mark W.

|Dean Gaucher||Ive had the jeep for about a month...i know its not the preferred set-up,but its what i have at the moment...[not enough cash for new gearing lol]....and wont 5:13s kill me on the freeway? im new to this,so bear with me...thanks|

You won't need to worry about "stripping" the splines off the gearing, the v6 engines don't produce enough horsepower to make that even a remote concern.
I have the extended stops on the stock tire carrier for my tire. Eventually I'll get a tire carrier bumper. But for now, I had to choose between having a matching spare or not. I chose the spare.

|Dean Gaucher||I have a 2010 sport,have 35's,3.73 gear [no problems],rear tire relocation [extension] and tail gate reenforcement kit from Quadratec,cost me 80 bucks total.The spare and gate doesnt even budge. And I know,it all depends on your use of the vehicle.mine is mostly street driven,maybe 10% trail. Thanks|

|jk'n||For rock crawling you might consider lower gearing. I have the 4.1s and with stock tires it crawls really well...translate: slow. With 35s I would have to regear for the same effect. Not rock crawling? No need for the regear. Power at the low end will be lacking though with 35s. You will notice it a bit on the highway. Not towing with it? Then that may not matter so much. Evin if towing with it, you may just have to shift down a gear to get back into the power band.|

The front and rear Dana's in the JK's are referred to ask "next generation" Dana 30 and D44's. They are completely different axle and wider.
|11-14-2010 12:06 AM|
|Ageless Stranger||I thought a few of the '07 models slipped out with D35s in them??? I know all new production models have the D44.|

|Heavy D||If you want to go with 35"s, you should really consider regearing for the power issue. The real concern is the axle/differential. The way that the Dana 35 is set up, the additional forces placed on it by the larger tires can bust the axle splines, especially when rock hopping. You may want to consider going to a Dana 44 to prevent this.|

|11-13-2010 06:58 PM|
|Boosta||Depends on how you drive. I test drove a stock JKU then a stock geared JKU with 35's. Going uphill was horrid on the JKU with 35's. All comments point to re-gear once you go to 35's.|
