Heavy Duty 2006-2010 Chevy/GMC Duramax Transmission Lines/Hoses 


  • 1/2" I.D. 5,250 PSI DOUBLE Steel Braided R16 Hose with abrasion resistant exterior provides more protection to prevent against rub through or road hazards
  • CR Performance uses High quality R16 hose rather than cheaper R2 like some competitors. R2 is the wrong hose for this application requiring turns and bends. 
  • We use 43 Series 1 piece zinc plated fittings, BTW Ferules are factory attached to the stem.. These "bite to the wire" type are much more secure and will never slip off. Our Competitors are using 2 piece 71 Series (single crimp line on the ferule, top to bottom). Those are the ones to stay away from in our opinion and knowledge in hydraulics. 
  • Made by CR Performance, a trusted USA manufacturer of the Duramax Transmission lines. 
  • Detailed, easy to follow instructions with photos. 
  • CR Performance uses only the best materials and make sure you are receiving a quality made product.
  • Lifetime Warranty for Quality...Buy with Confidence
NOTE: Fitment on non-OEM components is not guaranteed. Aftermarket coolers and radiators may need ORB M22 x1.5 to -10AN (JIC) Male fittings. Not included. (usually available locally if they're needed)
