SRW to DRW

Would it be possible to convert a light duty c2500 ( 6 lug) to c3500 dwd? Would the frame accept the components? I already have a donor for spindles rear axle and wheels.

@Dahead76 has a 2500 done this way. Maybe he can chime in.

Yes and no. You can convert it to a dually, but it won't have the same load capacity the C3500 would. Your frame isn't the same, and your light duty transmission isn't up to the same job the C3500's trans is. You can (and should) swap the braking system over from the C3500 though including the hydroboost.

The C3500 forged upper control arms will bolt right in place on your 2500LD frame. No need to move the lowers unless you think the bushings and ball joints might be in better shape, as they're the same. Spindles, rotors, calipers, no biggie.

The 10.5" 14 bolt rear will move right over, same spring perch width. Springs will move over too if you want 'em. Pinion yoke will not match your existing driveshaft so you'll need a conversion joint.

That's the broad strokes.. obviously there will be minor details here and there.

Thank you Richard. I forgot to mention I am also converting to NV4500
