Here is a VCW heavy axle I got with a bunch of parts. The axle has VCW embossed in the web. the axle measures 47" king pin center to King pin center. The measurement between spring perches is 35". spring perch holes are about 11/16". King pin holes about 13/16". There are 2 holes drilled in the web that are 1". King pin retainer holes are different from maybe wear. one is about 17/32" and the other 21/32". I believe this is a 4" drop axle. Please ask any questions but I don't know much about this axle but it does look very nice. asking $600.00 and buyer pays UPS shipping of 32 lbs or it can be picked up at my place or ??? Please PM me with your questions. Thanks
