Thuren's Long Travel leaf springs are designed to give the most suspension travel possible, while still being able to hold up to extreme off-road abuse. These leafs are very soft, helping to improve street ride quite a bit.
- 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, more like 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 IMPORTANT NOTE: These leaf springs are extended length, MANDATING Thuren's shackles are used, and the longest length position on the shackle MUST be utilized. Leaf spring damage will occur if the assembly 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!
Due to limited production, Thuren Fabrication items cannot be expedited. If expedited shipping is selected, we will credit back the shipping difference and ship via standard Ground shipping. Thank you for your understanding!

As advertised I got huge gains in rear suspension travel over stock leaves. Im running Bilstein 33-187228 shocks, cjc extended brake lines. The rock in the photo is 36" tall.
- Fits 2003-2013 4x4 2500 trucks, 2003-2012 4x4 3500, and 2005-2013 Power Wagons.
- The greaseable 75D bushing we use as the shackle pivot provides smooth bind-free shackle swing.
- 3 position height adjustable, when used with OEM or other brand leafs. Stock height, 3/4" lift, and 1-3/4" lift options.
- Thuren LT leafs must use the longest span mounting, so they become non-height adjustable, with Thuren LT leafs.

Awesome Product! Built a lot stronger than OEM shackles and installed easily! Buying through CJC has been a breeze!

2007 Dodge Ram 2500. Bought the thuren 3 inch coils for the front and I did measurements before ordering. Figured I needed the shackles for the rear otherwise the rear would be sitting lower than the front and I wanted dead level. These shackles were perfect. No noise coming from them. And my truck sits the same front to rear.
