Overview
The Poison Spyder Lower A-Pillar Kit, bare steel, part number 13-18-011, is a pair of lower A-pillars that tie the cage A-pillars to the floor on a YJ, written for the Jeep Wrangler YJ, 1987 to 1995. The kit is sold as a pair, one driver side and one passenger side, and the gussets as needed are included.
The A-pillars are designed to support the forward section of the cage while fitting closely around the dash. That keeps the cage low profile, so it does not hinder entry or legroom. The pillars are the same components Poison Spyder uses in its production YJ cages.
Key features
- Driver and passenger side A-pillars sold as a pair
- 3/16 inch plate steel, CNC laser cut and precision brake-formed
- Gussets come unwelded so they can be TIG or MIG welded to match the cage
- Low profile fit around the dash
- Same components used in Poison Spyder’s production YJ cages
- Secures the cage to the floor
Roll cage welding basics
Weld-in parts depend on sound joints to hold up in a rollover. Before welding, clean the mating surfaces to bare metal and fit the pillars against the dash and floor so the gaps are even. Tack the joints in several places first, check the alignment again, then complete the welds in short passes so heat does not distort the thin plate.
Inspect each weld after the cage is finished, looking for cracks, undercut, porosity or uneven bead shape. Gussets should be welded on all sides of their joints where the design calls for it, so the load moves through the cage instead of concentrating in one spot. Recheck the cage after the first off-road outing, because new welds can crack if the joints were not fully penetrated.
- Clean mating surfaces to bare metal
- Tack and check fit before final welds
- Inspect welds for cracks and undercut

Vehicle fitment
These A-pillars are written for the Jeep Wrangler YJ, 1987 to 1995. Confirm your Jeep is a YJ before ordering, since the pillars are shaped around the dash of that body.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The pillars are installed by welding. The gussets arrive unwelded, so they are tacked and welded with TIG or MIG to match the rest of the cage construction. Fit the pillars against the dash before the final welds.
What’s included
A driver side and passenger side lower A-pillar, with the gussets as needed.
