3500 SRW vs DRW


Recommended Posts

Besides the obvious, are there other mechanical differences?

  • Do the 17" vs 20" wheels create a different ratio? 
  • Does the DRW have bigger brakes?
  • Anything different with the axle?
  • What else?!

1.  3500 srw and drw run the same rear axle ratio.  The smaller OD tires on drw help with giving it a higher overall gear ratio.

 

2.  I believe the front brakes are same but rear are larger on drw.

 

3.  Gear set I believe are the same but axle shafts are stronger on drw.

 

4.  Biggest difference is the rear spring pack.  The drw has alot more force in the underloads.
