Spidertrax Poly Performance Links

The links themselves can be made from a plethora of materials. Spidertrax and Poly Performance are both offering heat-treated chromoly links made to order. Many rockcrawlers build their links out of 7075 T6 solid aluminum for a strong, lightweight link. We have seen a lot of rigs also running simple DOM tubing (check out our suspension story elsewhere in this issue with examples of different link suspensions), but the wall thickness should increase if you go with DOM instead of chromoly. A 1/4-inch-wall tube with a 1/8-inch-wall tube sleeved over it seems to be a pretty common DOM link for smaller vehicles. As you get up into fullsize truck weight, you'll want to start looking into thicker wall material and/or exotic material like chromoly.
