2003-2009 Dodge Ram 2500 Thuren Long Travel Leaf Springs

SKU: TF-LTLF1-0313

Regular price $1,850.00

Our Long Travel Leaf Springs are designed to give the most suspension travel possible while holding up to extreme off-road abuse. These leafs are very soft and give the best street ride on the market.


  • Heat treated, shot peened, and manufactured from the highest quality materials available.
  • Can supply true, clean, 18" of active suspension travel.
  • Extended design uses shackle length and motion ratio to amplify wheel travel.
  • Very soft spring rate and ride feel, similar to a 1/2 ton truck.
  • Designed to mount using the factory OEM u-bolts.
  • High quality PTMEG Polyurethane bushings.
  • Moves rear axle back slightly to help 37" tires clear the fender better.
  • Almost completely eliminates axle drive chatter in soft terrain/sand.

Shackle Note: These leaf springs are an extended length, MANDATING Thuren Shackles are used, and the longest length position on our shackle MUST be utilized. The factory OEM shackles will not work and leaf spring damage will occur if the shackle is not installed properly!

If you tow/load heavy weight often, please consult with us prior to purchase to make sure these are the right leafs for you!

Shipping notes:

We ship these leaf springs via UPS ground. They are very heavy and awkward, so picking up at your local UPS hub might be something you want to consider. If you prefer to do that, once you get a tracking number from us, call UPS and have them kept on hold at your local UPS hub, and you can pick up there.

Shipping cost for these leaf springs can be rather expensive, and the UPS quote system on this website is not always accurate. If the true shipping costs end up being more money than charged at the time of purchase, we will email or call you to discuss shipping options, and/or extra fee's due.

noise makers

i have had really bad luck with these leaf springs. they have been on my truck for about a year and a half and haven’t quit making noise. just an aweful metal on metal screech sound. i’ve taken everything apart and re-greased everything 3 times now and it’s still bad. sound like old rusty clapped out springs every time I roll over a bump. it seems like it’s the drop shackle feature that’s making the noise but it’s hard to pin point it. im not happy with mine and wish i bought something else

Worth it but not fun

Purchased a set of leafs for my 3rd gen 2500 and shackles to go with it. Quality is top notch on both.

The springs, well they suck to put in. Not other way around that.

Truck is sitting high but I expect them to break in with time. I will say that they are smoother just around town with typical California roads.

The only thing that did suck is that ups drug one of the eyelets while transporting it and did some damage.

HUGE improvement offroad and even on pavement.

I put these on my 06 ram 2500. Shocks are bilstien 5100s. Immediately noticed how my tires stay IN the dirt instead of bouncing over choppy washboard and potholed forest roads. They are just like any Thuren product, made to the higgest standards and perform better than i could have imagined. I have had back surgery and in constant pain, and these help a TON with keeping the ride smooth, even on the pavement. Soon to be paired with Thuren's 2.5 kings for even better ride quality. If youve wondered about getting these, dont hesitate. Id give it 10 stars out of 5 if i could.

Will note that they are not fun to install, especially by yourself on the street. Have a friend handy to maneuver these.

Leaf springs installed today

The install is done and drove the truck 8 miles home. It rides better than when it was new, I don't dread getting in the drivers seat and going anywhere now. Almost as smooth as the 2018 Cadillac. Directions were all good. Thank you for providing great service and great products.

Delivery of leaf springs

I ordered my 2009 power wagon leaf springs on Friday 3 February 2023 and received them the next Wednesday in Montana. Thank you Mr. Don Thuren for your prompt response and for delivering truly splendid products. My shackles have been shown to many shops and all were impressed with them. I'm very pleased with the resulting ride and will be ordering your drag links, tie rods, and boogie bumps...
