Again, thanks! | | | | Joined: Aug 2004 Posts: 90 Member | | Member Joined: Aug 2004 Posts: 90 | Has any body used Chevy Duty's 10/12 bolt 3'' rear end spring perch set up and did you have issues w/ the U bolts being to short?? I am swapping the rear end and using the stock springs and one would think that if this kit was sold to customers of AD / TF's it should fit the standard stock springs. The kit is made by classis engineering in Calif. When I called (CD), and advised them of this they said send it back, that the 'U' bolts are one length only. :confused: Well heck I've got the whole enchialada apart and I'm NOT waiting another week or two for something they don't have/ supply. CD said I had to return the entire kit to get credit and the supplier only makes the 7'' size. I'm off to a local suspension shop and have 4 made to the correct length, it took a half an hour. But it cost me $36.00 MORE. It's just a big bummer to spend that kind of money and not get what you should gotten in the first place. Their U bolt length is 7'' from the inside curve to the end of the threaded rod and I can only get one turn on the nut w/ no lock washer, and you need at least 8''. the standard nuts are .5 to .6'' long + washer and lock washer. I guess I'm just posting this as an FYI.
Any thoughts
Gooday Jim

I didn't use the orginal AD shock mounts and made my own. U-bolts worked just fine then. | | | | | Joined: Jul 2005 Posts: 2,031 Shop Shark | | Shop Shark Joined: Jul 2005 Posts: 2,031 | I have contacted CHEVY DUTY and they asked about my situation. REFUNDED MY COSTS for the replacement U bolts that were sent. Chevy Duty Has contacted CPP to inform them as to the WRONG length of U bolts supplied w/ the kit they make for Chevy Duty. All you have to do is ask, the squeeky wheel syndrome
CHEVY DUTY HAS COME THROUGH W/ POSITIVE FEEDBACK AND A QUALITY RESPONSE TO THIS SITUATION. I'm a satisified customer
