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. Both the upper and the lower plate have full side plates, which completely nest when welded together to form double-wall, seriously beefy, 3/8" thick sides! Why is that important? Check out the damages 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.
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 sheet metal. 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 sheet metal
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.
