Frequently Asked Questions About Freightliner SD 108-122 Frame Nut Covers

Will these frame nut covers fit my specific Freightliner model year?

These frame nut covers are designed specifically for Freightliner models SD 108, 114, and 122 manufactured from 2005 to present. They fit the standard frame rail spacing and bolt patterns used on these models. However, if your truck has aftermarket modifications to the frame rails or non-standard bumper mounting, we recommend measuring your bolt spacing before ordering to ensure proper fitment.

What material are these covers made from and how durable are they?

Our Freightliner frame nut covers are manufactured from either heavy-gauge 304 stainless steel or chrome-plated ABS plastic, depending on the specific product you choose. The stainless steel options offer superior corrosion resistance and typically last 10+ years, while the chrome ABS versions provide an excellent appearance at a lower price point but may require replacement after 3-5 years in harsh conditions.

How difficult is the installation process and what tools do I need?

Installation is straightforward and typically takes 15-30 minutes. Most covers simply slide over existing frame bolts and nuts - no drilling or modifications required. You'll need basic hand tools including a socket set to remove and reinstall your bumper bolts. Some models feature a snap-on design that doesn't require any bolt removal. Always ensure bolts are torqued to manufacturer specifications after installation.

What finish options are available and which holds up best?

We offer three main finishes: mirror-polished stainless steel, standard chrome, and powder-coated black. Mirror-polished stainless requires occasional polishing but never rusts or peels. Chrome provides excellent shine but may show pitting after several years in salt-heavy regions. Powder-coated black offers a subtle, professional appearance and excellent durability but may show scratches from road debris over time.

How many covers come in a set and what exactly do they cover?

Sets typically include 4, 6, or 8 covers depending on your bumper configuration. A standard 4-piece set covers the main bumper mounting bolts visible from the front. The 6-piece sets include additional covers for auxiliary mounting points, while 8-piece sets provide complete coverage including frame extension bolts. Check your specific bumper mounting configuration to determine the correct quantity needed for full coverage.
