its an 2004 TJ Rubicon, 4.0 and 5 speed. No lift, stock wheels and tire size. Its looking a little saggy in the front, and I currently have 1.5" of uptravel before the bump touches the pad. I'm reading this should be closer to 3" or 4", which would match the rear. I checked for any bump extensions, none installed. While looking under it I noticed some red paper tags on the front springs. I'd suspect they are not factory tags but they are Mopar tags.

The PN reads 52088129AB, so no guesswork on what springs are installed. Any idea if these are for the 4 banger? The cross references I've found so far indicate they fit the 2.3, 2.5 and 4.0 TJ's but no spring rate info.

Those are the stock springs. Easy enough to measure them to see how much they've sagged. 12" front/8" rear.
