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
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
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 2007-2011 JK's, both 2-door and 4-ddor,
with either manual or automatic transmission.
