Suspension Helper Springs for a 2015 Ram 3500 4x4 Towing 5th Wheel Toy Hauler w/5K Pin Weight  

Updated 03/11/2016 | Published 03/10/2016



Question:

Hi, Im considering the SSR-302-54 heavy duty vs the SSR-302-47 medium duty helpers, and my question is which should I go with for sag prevention. I have a 2015 ram 3500 crew 4x4 and I pull a 44foot toy hauler with around 5000# pin weight. I only pull it 3-4 times per year, but when I do there is considerable sag which I look to get rid of. Your help is appreciated... I also am considering the Timbren TDRTT3500E... thanks,

Expert Reply:

For your 2015 Ram 3500 4x4 and your heavy toy hauler trailer I strongly advise going with a heavy duty option for rear helper springs. A light or medium duty just won't offer the support that you will need for this particular trailer.

For SumoSprings the heavy duty part for your truck is # SSR-302-54.

For Timbren springs I recommend using # TDR3500CA which is rated for 8,600 pounds. The one you mentioned, # TDRTT3500E, is for truck models turned into service vehicles and utility trucks.

I also recommend some support for the front axle, # TDF25004B, because the trailer is so heavy and adding rear springs will put more stress on the front axle.
