I've gotten to 80 with mine. It was slightly down hill, too. Does it take anyone a while to accelerate to merge on the highway? Forsome reason, mine does

I can usually merge onto the freeway doing 70+ when I run 1st and 2nd gear to the higher ends.

I drive 80 pretty often with my stock engine, 4:10 gears, 35's, and superchip....smooth as can be. I think I've gotten to around 95, but that was unintentional. Just driving down the interstate and looked down and noticed it. Very happy with my jeeps performance. Looking forward to putting 37's on and seeing if it lags much.

95 getting onto the highway, people were coming up fast so I floored it. Looked down and was pleasantly surprised as it did not take a whole lot of effort to get there.

I've had mine around 95. I heard there's a company who does custom supercharges for Offroad vehicles that will raise horsepower 1000+

About 97 , before lights were added only about 90 now with lights on not enough room to push any more than that on the highways around here.

99mph for me. i hit 99 and the speedo was shaking and the engine was whining SO loud! so i figured that was a good indication that my jeep was tellin me to stop lol

Over 100 that's with 32" tires and 3.21 gears.

On the GPS it said 96. I was driving across Nevada, Hwy 55. Just cruising, the Jeep felt the same as if I were driving 60. My average daily speed on the interstates here in the Tampa Bay area is easly 75-85 mph. The 4:88's make it so simple.
