1999 Cummins 2500 Carli 3" Pintop work with 37s?
 

Sorry for another suspension thread, but I couldn't find a definitive answer in the other threads I looked through. I have a 1999 24V Cummins Quad cab 4X4 that is currently stock with no leveling kit. I am planning on putting on a 3" Carli system with full leaf packs, extended control arms and extended sway bar end links (Probably the Pintop 2.5s, but may go with the Bilstein 7100s if money becomes an issue).
The product page on Carli's site says that this lift will work with up to 37" tires. I have 33" Toyo M/Ts on factory 4th gen wheels. I want to keep my 4th gen wheels and put 37" Pitbull Rocker Radials or Toyo M/Ts on them. Does anyone know if they will fit without rubbing anywhere with the 3" Carli system? Future plans are to install a high clearance front bumper, but that probably won't happen at the same time. Thank you in advance for your help.

Dodge increased the 4th backspacing to 6.50" from 6.25" yielding a rim that hugs the body more thus there would be less clearance for tires.
Carli didn't have answers?

The last time I talked to them, I didn't know what my backspacing was. The product page has this information: Wheel and Tire:
This system will fit up to a 37” tire with our High Clearance Control Arms and Full Progressive Leaf Springs on wheels no more than 9” wide with 5.75” of backspacing. If running factory control arms or wheels; we recommend an All Terrain 35” tire. The more rubber, the better the small bump compliance will be at proper inflation pressures. The ride will firm up as you go larger in wheel diameter. For more details, see our article on wheel and tire selection and tire pressures: In my case, I won't be using factory control arms. Instead, I will be using Carli's extended control arms, which I believe are bent for more clearance. My current tires are 295/70R17s and I don't want to go any wider than that if I can help it, just taller. My other option if I have to change wheels (and it looks like I may have to) are the AEV Katla's. Those wheels are 10" wide, but only have a 4.83" backspacing, so they may work better. Would I be better off with Thuren 3" front springs for just a bit more lift in the front (particularly since I plan to add a 12K winch in the future)?

Thanks,
Tom

Thuren's coils ride extremely well. His 2" coils yield 2.75" of lift on a 2nd gen.
Aaron@ Thuren is very friendly and knowledgeable. You'd be pleased to speak to him.
My friend has the AEV's on his '05. 17" with 6.0 backspacing. Nice wheel.
CJC Offroad @ Best 4x4 Truck Wheels | Method, Trail Ready, BMF & More sells both systems but not the AEV wheels. he knows everything.
Good luck.
