I received my new Curt Weight Distribution System C17062 Round Bar - 10K GTW, 800-1K TW.
Nice Set up, Now The rear of my truck is up where it is supposed to be, I installed it with all of the washers (6) in the head adjustments, The TW of my trailer is 866lbs.
Note: In the beginning of this looking to upgrade my Reese 49901 Weight Distributing system 10000 lbs. [GTW]; 550 lbs. [TW], I was told the Reese 49901 Upgrade Spring bars were obsolete no longer manufactured. (True)
When I called Curt to see if there Spring bars 10000 lbs. [GTW]; 1,000 lbs TW
Will fit a Reese 49901, they said NO.
I would like to Share that Curt Spring bars 10000 lbs. [GTW]; 1,000 lbs TW Fit
Perfect in a Reese 49901 Weight Distributing system.
I measured both Reese spring bars and Curt spring bars, They are both the same, +/- .005".
Check out photos, the Groove, length, OD Diameter, angle, both are the same
I hope this will save other people with the old obsolete Reese 49901 Weight Distributing system from having to but a whole complete Curt system when they can use the round Spring bars, in a Reese 49901 round spring bar head.
