Truxxx 3"/1" Leveling Kit On '03 Sierra 1500 4wd-tire Op

chaps80 · September 10, 2011

I recently installed a Truxxx 3"/1" leveling kit on my '03 Sierra 1500 4wd. Also installed new Rancho s5000 shocks all around.

I'm currently running 265/75/16 tires(same ones I was running before the kit and shock install), and definitely want to go bigger. What i'm wondering is just how big can/should I go? Trying to decide between 285s and 315s. Found a couple good used sets of each in the local classifieds at good prices. Will the 315s add too much stress on the stock driveline, as i've heard? One tire size is'nt worth a costly replacement.

Thanks for any help.

33" tire max IMO. The 285/75/16 would be approximately 33x11, max you should be able to go and may need to do a little trimming at full lock. Anything larger than that will be to large for the leveling kit you have installed.

last person i saw put 315's on with a leveling kit took a saw-zall to the front bumper

Yeah, the 33s seem to be the best option. I looked at the Truxxx site and that's the size they say the particular lift I have will allow (16"-26" rims, stock offset).

Couldnt find the kit on the site at first. Seems they changed the name of it. Now its the "1999-2007 Classic 4x4 Pickup Lift Kit". Whatever.

IMO, even on the stock wheels I like 305's. I know what everyone is thinking about too wide but I have seen alot that look really good. If I had the older body style thats what I would go with.

How do you like the truxxxx leveling kit? About how much did you pay for the lift? How was it on the install?

i have the 3'' truxx and i put on 33x11.50 tires. and they rubbed hard. i did a pretty big trim on the bumper they just rubber on the mud flap and back of the fender on turns. i put on a 3 '' body too and they still rub the odd time in hit a bump while turning slightly.

400 for the kit i believe and i don't know what the install was but it took them all day since my keys were rusted in the truck,

Wow, long time since i've been on here. haha

As for the kit, (if you still care lol) its decent. Looks great(get tons of comments on it), but rides pretty rough! I paid a bit over $400 at Kal-Tire. They wanted around $600 more to install it, so I got a mechanic friend of mine to do it for $150. He said it was'nt bad at all, just had trouble with one of my keys being rusted in. That and the U bolts that came with the kit ended up being too short after installing the kit's rear blocks. lol Cost me another $50 to have a set made at a local machine shop.

My 33/12/15s ended up rubbing hard when turning, just like the guy above said happened. Took the bumper valence and mud flaps off, and the tires fit. Have a 1.5 inch body lift thats going on the truck soon. After that, things should be more than fine.

Overall though, If I was doing it again, i'd probably save up for a 4 inch suspension lift. Still might. After all this time riding on the truxx kit, i'd prolly have one right now had I waited.
