We are proud to offer built to order custom length 4130 links. These are built out of 2" .25 wall chromoly DOM with tig welded hex tube adapters on either end. Currently we only offer these for 1.25" - 12 tpi heims with Left and Right hand threads on either end.
After tig welding, each link is re-tapped to ensure thread quality, then heat treated before final shipping. Please allow 1-2 weeks build time. Links are measured from end of threaded tube adapter to end of threaded tube adapter. These will not gouge and deform like soft aluminum links will.
