The Deaver Spring U539/540 spring under conversion packs are increased capacity springs, designed to support weight of a bed topper and steel bumpers and does not ride too harsh when unloaded.  These fit in the stock hangers, but require a spring under conversion kit like this one >> SUA KIT  to install with perches welded under axle.  

The price includes FREE BUSHINGS.

This spring pack is an excellent choice to be used together with the Archive Hammer Hangers or even the Shackle flip, which provides lift.

Specs on U539/540 HD packs:

-Designed to handle considerable weight of shell, bumper, racks, sliders etc.  Definitely the right pack for overland SUA

- Approximately 1" lift with 500 lbs in bed 2005-2017 Double Cab Tacoma, my DCSB shows 2" lift at stock weight.

 (DCSB and DCLB are virtually the same, the Access Cab with get MORE lift as the cab weighs less and CoG is forward)

-U539 is driver side, U540 is passenger side, which helps address the Taco lean 

-Capable of approximately 12"-13" travel with Hammer hangers or properly setup shackle flip.

-These packs are designed with a removable 3rd leaf (from the top).  This is advised on the Access Cab when used with stock or Hammer hangers.  These HD packs are a good fit as is when used with the shackle flip 

Eric's review (2/15/2018):

I've had the U539/540 spring under conversion on my truck for several months with the Hammer hangers.  My DCSB got about 2" lift unloaded, with 800lbs its about stock height, with 1000 lbs it was lower than stock, but I can say they handled the weight quite well.  Unloaded the ride is pretty firm (but not really harsh) due to being designed for weight.  With some weight added, the ride is very smooth and smaller bumps are no longer felt.  I plan to remove the 3rd leaf from the top as the ride is too firm without any weight for my taste, which makes sense because I'm not really using it as intended at stock weight.
