Extreme Duty Crossmember Poison Sypder

Poison Spyder JK Extreme Duty Trans-Mount Crossmember

Replace your JK's weak stock transmission crossmember with Poison Spyder's Extreme Duty Crossmember! This ultra-beefy crossmember is constructed of two pieces of CNC laser cut, precision brake-formed 3/16" plate steel. Check out the damaged stock crossmember in the photos below. When getting high-centered on the rocks, with the entire 5,000+ pounds of a trail-ready JK resting entirely on the crossmember, it can tend to bend upward in the middle, or as we say, "Taco". The double-wall sides of the Poison Spyder Extreme Duty Crossmember put the extra strength where its needed most to prevent the Taco-effect—in the side walls of the crossmember. This specific part number is designed to fit 2012 & later JK's.

The 3/16" (.188" thick) top plate and bottom plate provide far superior protection against dents and bends than the stock crossmember, which is made of a piece of 1/8" (.125" thick) and 14-gauge (.083" thick) stamped sheetmetal. Incredibly, the Chrysler engineers decided to put the much thinner 14-gauge piece along the bottom, making it crumple at the mere sight of rocks. The steel used in the Poison Spyder crossmember is 33% thicker on the top plate, and 2½ times thicker on the bottom plate. And the 3/16" steel plate of the Poison Spyder Extreme Duty Crossmember has brake-formed corners all the way around—there are no welds on the box corners.

Inside the crossmember, Poison Spyder fabricators have welded in four DOM tubing spacers to provide crush-proof strength at the crossmember mounting bolt locations. These are made of .120" wall DOM tubing. Compare that to the stock crossmember, which uses stamped sheetmetal spacers.

The Poison Spyder Extreme Duty Crossmember matches the external dimensions and bolt locations of the stock crossmember. All stock skid plates that were attached to the stock crossmember attach to the Poison Spyder Extreme Duty Crossmember. Any other manufacturer's aftermarket skid plate system that attached to the stock crossmember should still attach to the Poison Spyder Extreme Duty Crossmember.

The Poison Spyder Extreme Duty Crossmember is shipped as bare steel, ready for you to paint or powder coat in the color of your choice. This part number is for year model 2012 & later JK's, both 2-door and 4-door, with either manual or automatic transmission.
