I just installed a 2" RL kit and new rims/tires. I've noticed a much firmer feel up front, especially if I hit a pothole or rigid bump. I'm getting rattles inside the cab that weren't there before. Is this normal and is it the kit or possibly the new tires? Running Nitto TG's. Any help is appreciatd.

 

The spacer shouln't affect your lift. It's probably the tires. I'd suggest checking the air pressure. I know all the shops in my area tend to inflate every tire they install to the maximum pressure listed on the sidewall which is way too high for daily driving.

 

I second Wandell's assessment...lower your air pressure. If you got the adjustable RL, than obviously dial it down. Finally, our our trucks are notorious for the ashtray to rattle. Some felt tape on the backside and any plastic-on-plastic will fix it. I'd like to see some pics...

 

Yeah, I didn't get the adjustable ones. The tires do feel very hard for some reason. Maybe I'll take your advice and let some air out. Also, my shop put Nitrogen in my tires instead of air. They did it for free since I spent so much money, but I wonder if that has anything to do with it. I hope I can mix air and nitrogen if it ever comes to that.

See this thread for pics. I posted pics twice in the thread so scroll down to see the better ones.

Your truck looks fantastic...congrats! When I did my lift, I had about 48psi in my 35's but I also have the Rancho 9000xls. It took a while but I had to dial in the shocks and the tire pressure for that "perfect" ride. Too harsh, and the rear would bounce out from under me (scary when on the highway). Too soft and the ride is just too mushy with a lot of sidewall roll. In your case, the same would apply. Drop the PSI and you should be fine. One thing to consider is that the weight is mostly in the front of the truck, so my fronts are about 5-10psi higher than my rears. If I am going to carry a load or tow the boat, I air up the rears. It may sound like a pain but it really isnt. Just a few minutes on the air compressor and its done.

 

What do you guys recommend for tire pressure? I haven't checked the tires yet due to the storm were experiencing, but I do know that there is an 80 psi Max on the tire. Should I scale this down to the typical 35 or 40 psi????

 

I'd try 45. I wouldn't go lower than 40psi.

 

I checked the pressure earlier today. They were set at 35psi. I think I'm noticing the difference much less the more I drive, so it might just be the difference b/w the new tires and old tires. Thanks for the help man.

 

Nitro in the tires is great. Your tires will be less likely to "loose air" and it helps reduce moisture inside your tire. Nitro is commonly used in the tired of heavy machinery used in some coal mines. If your pressure does get low you can pump air in them, but you should then have them purged and refilled with only nitro when possible. My shop did this for free when I havd to do it. Nitro should not create a difference in ride quality.
