Compensating for lumber rack and tool box weight

So I decided on a small lift, 5100's at 1.75 and since my truck carries the permanent weight of a full lumber rack, including a mesh panel across back window and two side rail mounted tool boxes, I thought a wheelers 1 1/2" add a leaf would be in order to bring it back to stock height . Do I really need new rear shocks, Or can I get by for a minute, since the ole' lady already wants to kill me? I assume my leaves have sagged already from the extra weight, but I didn't measure before..

 

Why not get the wheeler hd leaf pack

 

I have a 2013 AC TRD Off Road PreRunner. I have a Leer 180CC shell and an Aluminum RackIt rack. I have the Wheelers HD AAL leaf in mine and it rides great. Though if I had to do it over, I would probably just go with a replacement spring and not mess with the factory springs. The factory leaf springs are just not that good, and it is not all the much more expensive to just do it right the first time.

 

Just got the package from wheelers today, still unclear if I need new rear shocks, I figure I will be just above stock height w leaf installed and permanent rear load from lumber rack and tool boxes. By the way stock shocks only got 2000 miles on them...

 

i say scrap the 5100's, go with springs that have 2" lift and made for about 175lbs extra weight, get stiffer front stuts then use 3" Dakars in the back.

i used iron man, rides better than stock!

 

It's been said before and it seems like you already bought the springs, but your rig would be a perfect candidate for Firestone Ride Rites with the Daystar Cups. Have a Tundra with a Rackit Rack and side boxes so it be loaded all the time...stock TRD OR springs with the air bags and works awesome!

Note: If you do anything that puts you back to stock or above stock with weight in the bed be sure to add an extension to your brake proportioning valve as with the new height the rear brakes will act like you have an empty truck.

 

Thanks for the advice on the brake proportioning system, I will do more research on that before I start wrenching, still unclear on new shocks, but I figure I'll play it safe, pick up a pair and extend the rear break lines for more lift down the road.

 

BPV valve extension is a first gen thing no ?

 

Not sure....don't have my Taco yet...just know there was one on my Tundra that you had to adjust / extend to compensate for a lift to stock when loaded....my Tundra is loaded all the time so mine is simply set full open. Did they eliminate this on the newer Tacos?
