We've taken big-rig spring technology and adapted it to fit your offroad lifestyle!  These rad springs are completely different from their sibling multi-leaf elliptical.  They carry a heavier load, are more resistant to permanent deformation (sag), and they're 20-30% lighter in weight!  They're also more smooth-riding as they completely eliminate inter-leaf friction.  They're commonly found supporting the front axle of road-going medium and heavy-duty trucks.  

We've designed them to give approximately 2" of lift at +400 pounds capacity.  If you have a bed rack and additional permanent weight like a roof-top tent, these are perfect for you.  Like our Broverlands, they're great for guys & gals who like to keep a lot of gear in the bed of their truck or do some heavy hauling.  They're pasture-raised, free-range, cage-free, non-GMO, and manufactured right here in the USA.  Heat-treated shot peened for stress relief and painted to resist corrosion.  They feature UHMW liners and OE-style rubber bushings to prevent squeaks and dampen vibration.  

Includes:

  • 1x   Alldogs Offroad Parabolic Leaf Pack, Pair
  • 4x   9/16" U-Bolts 

Fitment:

  • 2005-2021 Nissan Frontier
  • 2022-Present Nissan Frontier

Notes:

  • 9/16" u-bolts are supplied.  It is necessary to drill the factory u-bolt plate through-holes to 9/16".  Torque to 90ft/lb. 
  • It's recommended that you have at least 200lb permanently added to the back of your truck for the best ride quality.

So this took some time to install.. I'd recommend expecting it to take all day so when you come across some bolt that's really seized up you are all set.

ALSO grab a 9/16 bit before hand! Save yourself a trip to the store mid way in.

Installed with Bilstein 5100s, backend rides stiffer which is perfect for my camper trailer. Without any load it rides more "truck like" not terrible but certainly firm without weigh.

Good 2 - 3 in of lift, I was replacing stock springs with a 2 in lift block and the truck looks taller.

Very minor negative is paint seems easy to scratch, I resprayed the springs before installing.

What a difference these springs make!

My '11 Frontier was getting a bit soft and settling more when loaded. The back end would bottom out over bumps when pulling the camper.  
Put a set of these Parabolic Springs on, along with the Bilstein' s recommended by All Dogs, and gained 3" at the back of the truck.
Now when I hook up to my 21' camper the back end hardly settles and the ride is solid and stable over bumpy, uneven roads.
