2003-2009 Dodge Ram 2500 Thuren Long Travel Leaf Springs

SKU: TF-LTLF1-0313

Regular price $1,650.00

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.

Rides great but squeaks like it’s 100 years old. I thought it would get better after a few miles but hasn’t. Over 2k miles later still squeaks.

Great product, superb shipping with killer instructions

Couldn't be happier. Ordering process was cake, super helpful staff. Parts were in stock and shipped WAY faster than I expected (ordered leaf springs). Packaging was top notch and the instructions got me through the install. 10 outta 10 would highly recommend.

I love these springs much more comfortable for daily driving on these crappy CA roads. I still need to reroute my driver side Ebrake cable and install a longer hyd brake line to get full use of the spring travel

Great product

Great product, fast shipping. The only reason I didn’t rate it 5 stars is because when it showed up the whole leaf spring wasn’t wrapped with bubble wrap.. only the ends were. Resulting in scratches on the spring itself. Other than that great quality spring can’t wait to see how it handles on the truck.
