If I am upgrading shocks and adding 2" MFC lift but want to replace springs with brand new MOPAR TH springs (as some have suggested) does anyone know the specific part number on replacement TH springs?

Searching MOPAR has not narrowed it down and not sure which specific spring my TH has. Definitely don't want to buy the wrong ones and lower the TH.

Who has the most miles on their trailhawk? Mine has about 120k now.

Rear springs, right? (front are struts)

Well, if that's the case then yes. I didn't realize front was different from the back.

There's front springs too, they're not part of the strut. New struts don't come with springs, except the Dobinsons I think...😎

You're correct.

• I generally get loaded struts (the struts come fully assembled ready to install with the springs already on).
• One could buy unloaded struts in which you need to take your old springs off the old struts and transfer them to the new struts but you'd need spring compressors (as well as take the strut mount off the top). For me, that's outside my comfort zone. Car springs=tremendous compressed energy at rest. If your spring compressors break, you don't have them balanced on opposite sides of the spring correctly or (believe it or not), you still hear about people who take a spring off with compressors and forget to keep it pointed away from their body or body part with an unhappy ending.

That's where my bravery ends! LoL!

Agree completely about buying loaded struts. Had a couple of close calls with flying springs back when loaded ones weren't so readily available. The OP has 120k on the clock, so the original springs are probably tired anyway.

I replaced struts and shocks, but used the original springs. Is there a problem with your current springs?

If you go to Mopar Parts Online and use your VIN, you'll get the correct part numbers for everything.

I'm not noticing any obvious issue with suspension. Over time they just kind of slowly go and you don't realize how much until you change them out. My TH is sitting at 122kmiles, and the offroad miles have been few. Overall, I could not be happier with the performance of the suspension on or off road. It has done very well.

Still hungry for more ground clearance and I feel I will keep this TH for another 100k miles (knock on wood) since I have a lifetime wrap warranty. As long as I don't bust a 2" increase of lift, my warranty stays intact, but I can't say the same for my muffler (it has some dings for sure).
