I have a broken torsion axle. TIE DOWN ENGINEERING is worthless as any help in getting the correct replacement axle. I furnished them all the data on the trailer. They refused to send me drawings and diminsions on replacement axle. They shipped the wrong axle fedex at my expense. 300.00 freight. Now they are telling me its my fault ! Now they will research it again when they get around to it. BS.....Don't buy Tie Down !!
