Nilight Heavy-Duty Spring Mounting Base for Whip Lights – 2-Pack Black Powder-Coated Carbon Steel, Shock-Absorbing

Nilight’s heavy-duty barrel spring mounting base is a durable, carbon-steel spring mount that secures whip lights and antennas while protecting them from impacts and bending.

This spring mounting base is engineered for off-road and utility use: a powder-coated carbon-steel barrel with integrated spring gives your whip light or antenna a flexible, shock-absorbing connection to the vehicle. It accepts screws with diameters from 0.448" to 0.465" and includes stainless-steel fasteners so you can install it quickly and resist corrosion in wet or dusty conditions.

Will this mount fit my whip light or antenna?

The mount is made for shafts and screws with a minimum diameter of 0.448" and a maximum of 0.465". It is intended for non-spring-base whip lights—this spring mount replaces rigid bases to add flexibility and impact protection.

• Compatible screw/thread tolerance: 0.448"–0.465" diameter (check your part).
• Designed for M12*30 thread screws on the bottom mounting hole (0.47" vehicle hole required).
• Works with fiberglass CB antennas, center-load antennas, and many LED whip lights (non-spring models only).

How does the spring help protect my light or antenna?

The integrated coil spring allows the mounted whip or antenna to yield when it hits obstacles, dispersing concentrated impact forces instead of transferring them into the antenna base. That flexible response reduces the risk of snapping or bending during everyday off-road use.

• Spring design absorbs shocks from branches, tunnels, and wind.
• Reduces direct stress on the whip light or antenna base.
• Bending motion returns component to upright position after impact.

Is this mount rugged enough for outdoor and off-road use?

Yes—Nilight constructed the barrel and spring from high-strength carbon steel and finished it with a thick black powder coat to resist corrosion and wear. The kit includes stainless-steel nuts and washers to further protect fasteners from rust in wet or salty environments.

• Carbon-steel construction for impact resistance and durability.
• Thick powder-coating prevents chipping and corrosion.
• Stainless-steel nuts and washers included to resist rusting.

How easy is it to install and what vehicles will it work on?

Installation is straightforward and typically takes under ten minutes with the supplied hardware. Any vehicle or bracket with a 0.47" mounting hole and matching screw thread can accept this base—common fits include UTVs, ATVs, trucks, golf carts and more.

• Package includes: 2 spring bases, 2 stainless nuts, 4 stainless washers.
• Mounting requires a 0.47" hole in the vehicle or bracket and M12*30 thread screws.
• Compatible with Can-Am, go-karts, dune buggies, sand rails, pilot cars, and similar vehicles (verify size before ordering).

Who is this for? This Nilight barrel spring mounting base is aimed at off-road enthusiasts, fleet operators, and DIY vehicle modifiers who want a low-cost, durable upgrade that adds shock absorption to whip lights and antennas. Choose it if you need a rugged replacement base for non-spring whip lights, want improved impact resistance, and require corrosion-resistant hardware for outdoor use.
