Our 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, and give the best street ride you can get.

Details:

  • 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 do. 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.

Included:

  • Assembled Leaf Springs (x2)

As good as advertised

I have a 2006 ram 2500 quad cab Cummins truck, it has 5” long arm kit with aftermarket rear leafs (no blocks). It rides amazing, my wife has a 2006 ram 3500 mega cab Cummins truck it HAD Carli front coils, thorn arms and stock leaf springs, it now has Thuren front springs, shackles, and leaf springs. Her mega cab rides almost as good as my long arm truck. The rear is definitely smoother with the thuren springs when compare to mine. If I had it to do over again on my truck I would have used the 3” thuren coils, shackles and leafs, its is really good. Both trucks have Fox 2.0s, thuren track bar, and airbags so they can actually haul cargo like they are made to do

2004 ram 3500 LT Leaf Springs

Single-handedly the biggest improvement in ride quality I’ve added to the truck. Thuren is the tits.

Long travel leafs

I have had these leafs on my 07 megacab for a while now. Noticed a bit of improvement on the street right away with good shocks. The biggest difference is something big pothole, bridge gap, railroad tracks or something similar. These sucked up the bumps great. Offroad, they are night and day to factory. I recently went to the sand dunes and these leafs got rid of probably 90% of the wheel hop I've had before. And yes I've always ran low 30psi air to help. On road you will still want to get your tire pressure down to at least 50 and you will be very pleased.

Beyond expectations

I installed the long travel springs after I’d already installed all the other suspension parts so I had a pretty good baseline to start with The springs not only help with overall ride quality ( expected) but they allow the shocks a better feel through the entire stroke… something very obvious the first time I was in rougher terrain…I can’t recommend them enough… and a big thanks to Don and his crew for all the help setting up my truck.
Again, I can’t recommend his long travel springs enough
