TundraGeneral discussion forum for the 2007 and later Toyota Tundra.
This is a discussion thread titled "Lifted 07-08 tundras", within the Tundra forum, part of the Truck Forums category.
Those of you with the 6" ProComp...how much change in power and mpg have you noticed??
I don't think the lift changes the mileage by itself. I've talked to guys who just did a leveling kit (no added weight) and bolted on the same 35-inch tall tires and they get the same poor mileage that I have experienced. I get about 11 mpg average for both highway and street driving, and those I talked to with just the tires got the same. These trucks seem super sensitive to tires size changes.
The power change is also relative to the tire size and not really the lift. I'm sure sticking that big front end up higher in the wind probably decreased the aerodynamics quite a bit. Mine is a bit more sluggish in the first two gears. It still comes to life beyond 3K rpm. Sixth gear is pretty much a waste. The truck really won't stay in 6th much on the freeway, it bogs down too much. The solution lies in aftermarket gears which hopefully we will see sometime down the road. These trucks with larger tires (and lift if you like) really needs 4.56 gears. ARB has just come out with a hydraulic locker for the Tundra. I'm hoping we will get one soon and in the process, prod them about if they have gears coming soon.
Thanx for the info TENT. I'm already running 35s (305/70R18) with a Truxxx 3" leveler, so it sounds like my truck wouldn't perform too much differently if I went to the 6" PC.
However, with 35s and the leveler, I'm still getting 13 - 14 around town and 15 - 16 on the hwy, which is nice.
I was just curious about the power as for a short time I had an F-150 with a 6" lift and the power went to ****, especially when towing my sled and trailer up I70...not to mention the mpg was lucky to be at 10.
Bottom line, I'm willing to sacrifice some power/performance/mpg for the look and advantages of a lift, but to me it's just a matter of beginning to stray too far from stock performance and seeing diminished capacities. Where that arbitrary line lies I'm not sure...
Maybe the difference in fuel mileage is that always talked about fuel mix difference, maybe the altitude. Hard to say. I've talked to three different Tundra owners with 35s and none were getting much more than 12 on the average. I can get 14-15 in mine on straight flat highway with zero grade and if I keep it no faster than 65 mph. Problem is around here there isn't much flat highway for more than a mile or two.
I had a 96 Chevy that I lifted on 35s, put in 3.90 gears and an exhaust and man that truck hauled ***! My crew cab Chevy was a different story.
I pulled a 26 ft trailer up north on T-day and the mileage was no different than if I weren't pulling it. That trip included crossing a mountain range. The Tundra has tons of torque and pulling, even with a lift and taller tires doesn't seem to be a problem at all. I'm probably going to put my factory air intake back in as I believe it will actually help on the bottom end. When I put the aftermarket intake in, it helped on the big end, but seemed to take a little out of the bottom end. Either way, there will be some compromise of take off power with larger tires, but I seriously doubt the lift kit itself would make any difference at all. The only real change with the kit is maybe the driveline angles and the addition of the weight of the parts of the kit.
If you are willing to lose a little performance and mpg, then you will probably be satisified with a 6-inch lift because of the advantages and of course those looks. I should reiterate, the lift and tires didn't totally take the wind out of the sails. But there was simply an obvious deteriation of fuel mileage and a little loss of that snappy acceleration that the Tundra is becoming known for in stock configuration. I should point out that IMO the Tundra has plenty of power for a lifted truck, particularly one with a six-inch or more lift. Our power is generally from the mid range on up. Mid range on up is going pretty fast in a big lifted truck.
Here's some more inspiration for you. I think someone else posted a photo of my truck on the first page (prior to the tint and steps)... here are some updated photos. There are more high resolution shots in my gallery.
I must also say, Altoun4040 - you have excellent taste sir!
Lukec - With mixed driving my driver information display shows approx. 12.0 mpg. Taking into consideration that there isn't a programmer to adjust the speedo/computer to account for the larger wheels & tires, that number is a little low... so I'm likely getting closer to 12.5-13mpg. I was getting 13.5 prior to the lift.

How does is the ride after the mods compared to stock?

Firmer to a certain degree. The add-a-leaf makes the back more stiff. If you don't like the bed bounce, you won't like it with the add-a-leaf. I plan on taking the lead out and installing a little taller block along with air lift bags to get the height but not super stiffen up the ride.
In my opinion much of your ride quality depends greatly on the tire you choose. With that said, I am extremely happy with my BFG All Terrains. My ride quality, and road noise levels are nearly identical to that of the stock configuration. I have had other, more aggressive, off road tires in the past and trust me there is a great compromise there. They are typically heavier, which makes them difficult to balance, most have a softer compound, so they will not last very long, and they also emit more road noise. All too often people make the mistake of buying a tire because it looks cool or is aggressive in appearance, and end up using a tire in an application it wasn’t intended for. This can result rapid wear, unnecessary annoying road noise, and possibly less traction than they could have achieved from a tire better suited to their driving conditions. The type of off roading you will be doing is often dictated by the region of the country that you live in, and as a result that region will also dictate which type of tire you will need. For me, living in the Sonoran Desert, an All Terrain tire works very well in the conditions I face on the trails I drive. I also commute daily with my truck, so an All Terrain tire is ideal for me. If you are truly concerned about ride quality; my advice is to determine what type of trails you will be encountering, how often you will be on them, and then use that information to make a tire choice tailored to your specific needs.
In regard to my other mods, more specifically – 6” lift, I do not feel that it has negatively impacted my ride quality. Please note that I have the stage 1 Pro Comp lift, and therefore do not have any type of aftermarket coil-over shocks. I agree with the other members in that you will certainly see degradation in your gas mileage; it is nearly impossible to avoid taking into account the added rolling resistance of larger/wider wheels and tires.
Good luck with your lift, I’m confident you’ll be happy with it should you go through with the decision.

what kind of steps are they?
