Stabilworks
My name is Mark Hodge, and I live in the Shenandoah Valley of Virginia. I have built thousands of stabilizer sets, for many different brands and models of tractors. I have extensive experience, building stabilizers for standard setups, as well as for custom needs (tractors that originally didn't come with stabilizers). 
Prices include everything- both sides, all necessary hardware, priming and painting, and shipping. They come turn key, ready to install.
I use high quality, common hardware, and US made steel. My philosphy is to build a strong set of highly functional stabilizers, with parts that will be as easy as possible to obtain locally.
I can ship to any US state, as well as most international destinations. Prices start at $200.00 shipped, and go up based on complexity of construction and shipping destination (all US addresses are flat rate shipping; International shipping rates vary). 
I work very hard to conduct business honestly, fairly, and as promptly as possible. I am sole owner and proprietor, so the same person that you communicate with is the one who is designing and building your stabilizers, as well as packaging and shipping.
