just got me an 01 1500 and going to replace shocks on the front and trying to figure out if it has a lift it sits up some but it does have 305 70 16 on it, how can i determine if it has a lift?

 

Look at the coils, see any spacers? More than one lift block on the rear leafs? Does the front sit higher than the rear when you have weight in the box?

 

theres only one block on the rear leafs the truck height to center of fender on front is 42 in and rear is 42 1/2 i havent hauled anything in it yet

 

Doesn't sounds like there's any lift to me. Unless there's a add-a-leaf. To be sure, make sure there aren't any coil spacers upfront.

My truck sat a good 3 or 4 inches higher in the rear than the front. After installing the 2500 front coils to level it out, oem shocks still fit. But I got the 2500 shocks just for added measure.

 

what do the spacers look like? and what would be a good shock and place to get them? i dont do any off roading more road use

 

Looks like a big hockey puck kind of. You'll see it on the top of the coil spring. here is a link to topguncustomz to give you an idea

As for OEM shocks, go to the dealer or RockAuto. Monroe seems to be a fairly good brand.

 

Rear blocks should measure 3"
Should also have 5 leafs in the rear if you got 4wd (I think its 5)
Pics would help too

 

yes it has a big puck looking block thats about 3 1/2 in tall on front my camera isnt working or id take pics

 

rear blocks are about 3 1/4 and has 5 leafs

 

Well, sounds like you have a leveling kit. OEM shocks will still fit.
Like I said, I got a pair of shocks for a 2500 for my truck, just went to the dealer to get them, free of charge I may add. lol
