860M Mamba Trailer

Raceline 860M Mamba Trailer: A Purpose-Built Trailer Wheel

The Raceline 860M Mamba Trailer is a monoblock trailer wheel with a clean multi-spoke face designed for utility, boat, and equipment trailers. As a single-piece monoblock wheel, it carries a straightforward, workhorse look built to take repeated highway miles and load duty rather than to chase a show-car aesthetic. It sits in the Raceline lineup alongside the brand's truck and passenger fitments.

Sizes and Fitments Stocked

This is the part most trailer owners come for, so here are the concrete numbers. The 860M Mamba Trailer runs diameters of 12, 13, 14, 15, and 16 inches, in widths of 4, 4.5, 5, and 6 inches. Offsets are held at 0 (listed as both +00 and 0), which suits trailer hubs and keeps the wheel sitting flat to the mounting face.

Bolt patterns cover a wide spread: 5x114.3, 5x127, 6x139.7, and 8x165.1. On the small end, the 5x114.3 12x4 is the entry point, with the 5x114.3 14x6 stepping up for larger single-axle setups. For heavier trailers, the 6x139.7 15x6 and the eight-lug 8x165.1 16x6 cover the top of the range. If your trailer uses a five-lug wide pattern, there's also a 5x127 option in a 15x6.

Finishes

The 860M Mamba Trailer comes in Black and Machined along with a set of coded factory finishes (A216329, A216330, A201418, A201419, A201420, A201421) that vary by size and pattern. If a particular look matters, browse black Raceline wheels and silver Raceline wheels to see the tones side by side.

Price and Who It Suits

Pricing runs from $119 for the smaller five-lug sizes up to $264 for the eight-lug 16-inch. That makes it a sensible pick for anyone replacing tired trailer wheels or spec'ing a new build who wants a durable, no-drama wheel across a range of hub patterns. If you also run passenger or truck rigs, siblings like the 145M Encore BMF, the machined-face 146S Matrix, the blacked-out 131B Evo Black, and the off-road RT951M Ryno serve different jobs entirely.
