GPCA Tie-Down Anchor & Bolt FAQ
1. What is the GPCA Anchor PRO, and what are its primary features?
The GPCA Anchor PRO is a quick-release tie-down anchor designed for Jeep Wrangler models. It replaces factory hardtop bolts, enabling faster hardtop removal while providing durable, versatile tie-down points for securing cargo.

2. How do I install the GPCA Anchor PRO?
Installation involves:
- Removing factory hardtop bolts.
- Aligning the Anchor PRO with the mounting holes,
- Placing the washers in the following order on the tub edge: rubber washer, metal washer, then bolt.
-
Insert the tip in the hole first, Hand-tightening the T-handle screws.
No additional tools are required. -
Over-tightening could impact the hardtop edge. With 6 of them, the proper torque is 158 in-lbm for each only, it's actually very similar to tightening a bike seat post clamp. (Ford Bronco models require 8 anchors.)
3. Does the Anchor PRO come in different colors?
Yes! The Anchor PRO is available in Black, Red, and Blue — so you can match or accent your build. Whether your Jeep is blacked out, running red recovery gear, or decked out in blue accents, there's an option that fits. It's a small but satisfying detail that pulls your whole setup together. 🎨
4. What is the GPCA Tie-down Bolt, and how does it enhance functionality?
The GPCA Bolt is a quick-release thumbscrew designed for Jeep Wrangler and Ford Bronco models or all vehicles or DIY projects with 8mm+ mounting holes.. It simplifies the process of hardtop removal and installation while providing secure fastening. For Ford Bronco 2021, there are extra 3 mounting points on both side on the roll bar/ roll cage (6 total both sides), in addition to the 8 mounting points on the tub edge.
5. How many bolts do I need for the top mounting positions on my Ford Bronco?
In addition to the 8 tub edge bolts, the Ford Bronco has top mounting positions that secure the front edge of the rear hardtop shell. These require GP-Star Bolts — the Anchor PRO T-handle does not fit in that space.
• 2021–2023 Bronco: 2 GP-Star Bolts on top (one per side) → choose the 10 Pack
• 2024–2026 Bronco: Ford added a second bolt per side for extra hardtop security, so 4 GP-Star Bolts on top → choose the 12 Pack
Select your pack size accordingly on the Bronco Tie-Down Anchor PRO page.


6. Are the GPCA Anchor PRO and Star Bolt compatible with my vehicle or other projects?
- GPCA Anchor PRO: Compatible with Jeep Wrangler JK, JL, 4xe, Ford Bronco and all vehicles or DIY projects with 8mm+ mounting holes. Not compatible with the Jeep Gladiator JT cargo tub — the T-Handle is too wide to rotate in that space. Gladiator owners should use the GP-Star instead.
- GPCA Star Bolt: Works with Jeep Wrangler JK, JL, Ford Bronco, Gladiator, and all vehicles or DIY projects with 8mm+ mounting holes.
7. Can the GPCA Anchor PRO or Star Bolt be used with removable window panels on a Jeep?
No, both the Anchor PRO and Star Bolt cannot be used with removable window panels on a Jeep, as they require a flat, solid surface for proper installation and functionality.

GPCA Tie-Down D-Plate and D-Rings FAQ
1. Can the GPCA Tie-Down D-Plate be used on other vehicles or projects?
Yes, the Tie-Down D-Plate can be used on any vehicle or DIY project with an appropriate mounting surface. For flat installations, adding a washer beneath the D-Plate is recommended to ensure proper clearance.
2. What are GPCA Tie-Down D-Rings, and what are they used for?
GPCA Tie-Down D-Rings are strong, versatile anchor points that can secure tools, straps, lights, carabiners, and even dog leashes. They complement GPCA cargo covers and other organizers, ensuring secure and efficient cargo management.
3. Can the D-Plate and D-Rings be paired with other GPCA products?
Absolutely! Both the D-Plate and D-Rings work seamlessly with the GPCA Anchor PRO, Star Bolt, cargo covers, and tie-down systems, enhancing your vehicle’s cargo management capabilities.
4. What is the washer order on the tie downs with the D-Ring?
- Rubber Washer: Goes directly against the vehicle body/tub edge. This seals the hole and protects your Jeep's finish.
- Metal Washer: Placed on top of the rubber washer for strength if there is no D-ring.
- D-Ring/ D-plate: Placed under of the metal washer.
- Anchor PRO / Star Bolt: The bolt is inserted through the stack and hand-tightened.
This arrangement ensures the D-Ring is secured strongly while allowing it to pivot as designed.
6. Will the D-Ring rattle?
No, they don't, we built the "clip" part as a "clamp" when the bolt is down it clamps down the D-ring so you can set it at any angle without any movement.

Are the Anchor PROs just for hardtop removal, or do I need to keep my hard top on?
Neither — the Anchor PROs stay in year-round as permanent D-ring anchor points, regardless of whether you're running a hardtop, soft top, or no top at all. Once installed, they give you a real tie-down hook for a cooler, gear bags, or recovery kit anytime you hit the trail — whether the top comes off or not: gpca.com/collections/tie-down-anchors
I can get D-ring bolts at Home Depot for $2 — what's the difference?
Hardware store bolts use the same M8-1.25 thread, but that's where the similarity ends. The GPCA Anchor PRO is CNC-machined with a built-in D-ring rated for tie-downs, a T-handle quick-release (no tools, off in seconds), double-washer protection that won't scratch your tub edge finish, and color options (Black, Red, Blue) to match your build. A hardware store bolt is just a bolt: gpca.com/collections/tie-down-anchors
