About this product
If your Jeep Wrangler or Ford Bronco uses oversized wheels, deep-dish rims, or a modified spare setup, rucRak Mounting Stud Extensions give you up to 3 inches of added stud length so the GRUNT can mount securely—even when your wheel depth exceeds the standard 5-7/8" fitment range. These extensions thread directly onto your existing rucRak studded lug nuts, closing the gap between your spare tire and the mounting plate for proper, safe installation.
Watch Video in Gallery before you buy!
NOTE If you have an aftermarket wheel, measure wheel depth by placing a placing a yardstick or a level flat across the tire and measuring from the lug nut to the outside of the tire, see the image below noting 5-7/8".
If that measurement is MORE than 5-7/8", then you will need to add these to your order.
Built from hardened, zinc-coated steel, they ensure secure, vibration-free mounting across daily driving, off-road trails, overlanding, and highway travel. Engineered exclusively for the rucRak GRUNT spare-mount system, these extensions can only be purchased with a rucRak or by existing customers and are not compatible with non-rucRak products.
