<div class="bbWrapper">Keep it civil and factual. <br /> <br /> Hurling insults at other members will not be tolerated and get you a timeout next time. You know who you are.</div>
 
<div class="bbWrapper">Bags aren&#039;t the only option to increase the payload. You CAN take it to a suspension shop and have leaf springs from a 3500 installed on a 2500. What else is different between 2500 and 3500 SO? Nothing! This would make it a 3500 with around 4000lbs of payload. Artificially low 10k GVWR is for registration purposes only and doesn&#039;t reflect the actual build materials quality and design.</div>

The entire rear suspension is a completely different design.<br /> <br /> For the OP, I&#039;d cut your losses now and trade it in on a 3500. That way you&#039;ll be legal, have a more stable platform, and probably be in the same spot cost wise vs modifying a 2500. Plus you can opt for the HO and get the Aisin transmission which is much more likely to last while towing.</div>

<div class="bbWrapper">What are the differences between a 2500 and 3500 single wheel?<br /> Just rear coil vs leaves? <br /> Front coils stiffer?</div>

Airbags quickly shrink that gap, and add lateral to the 2500 too. The only difference I’m aware of in the frame is the difference required for the different suspensions. <br /> <br /> Front suspension is the same, but according to Thuren the 3500’s sit 1/2” higher so there may be a slight difference in the springs. Ram specs show them sitting at the same height up front. <br /> Both the 2500 and 3500 can have a 6,000lb FAWR. <br /> <br /> That’s pretty much it.</div>
