Compare full-size and mid-size universal overland rack cross bars. Learn which cross bars fit your truck rack and gear load needs.
Quick answer
Choose TK-6125 full-size cross bars for larger trucks that need maximum load support; choose TK-6126 mid-size cross bars for smaller trucks where weight and space are tighter.
Why size matters for cross bars
Cross bars bridge the gap between your rack’s side rails and carry gear like rooftop tents, cargo baskets, or kayaks. A bar that’s too short won’t span your rack; one that’s too long can overhang and create wind noise or snag points.
Both TK-6125 and TK-6126 cross bars share the same durable 2-stage light textured black powder coat finish and multiple slotted holes for adjustability. The key difference is length and intended rack width.
Trade-off: load capacity vs. vehicle fit
Full-size bars (TK-6125) are built for full-size trucks and SUVs with wider racks. They offer more surface area to distribute heavier loads evenly. Mid-size bars (TK-6126) suit compact and mid-size trucks, where a shorter bar reduces overhang and keeps the profile neat.
If you plan to carry a rooftop tent or multiple recovery boards, full-size bars give you more flexibility for accessory mounting. For daily gear like a cargo bag or a couple of traction boards, mid-size bars are lighter and easier to handle.
How to choose: decision rules
- Measure your rack width first: Measure the distance between the inside edges of your rack’s side rails. Full-size bars (TK-6125) fit wider racks typical on full-size trucks; mid-size bars (TK-6126) fit narrower racks on mid-size trucks. Do not guess—use a tape measure.
- Match bar length to your gear plan: If you plan to mount a rooftop tent or a large cargo basket, full-size bars provide more support surface and accessory mounting points. For lighter loads like duffel bags or a few traction boards, mid-size bars are sufficient and less bulky. Full-size bars = heavy/wide loads; mid-size bars = lighter/narrower loads.
- Check compatibility with your universal overland rack: Both cross bar sets work with Body Armor 4x4 universal overland racks. The slotted holes allow you to fine-tune the position. If you already own a rack, confirm the bar series matches your rack’s side rail design. Don’t assume all universal racks use the same cross bar—verify part numbers.
