Have some fun with your regular mountain bike (straight 1 1/8" head tube OR OS head tube will work with this fork) or upgrade your current fat bike.
Black Sheep ti fork accommodates 135QR front hub, with 224mm (over 8.75") there is plenty of steerer tube to fit any bike. Have used it on both 27.5 and 29er frames. Great addition to any rigid non-fat bike (think Surly Krampus only lighter). The velcro-like hook-up of the light front wheel in fast turns is amazing.

The fork has an 1.5 King baseplate for an OS or tapered head tube (or can be swapped to an 1 1/8 one if you have an 1 1/8" headtube) and includes an adaptor for post mount brake. With the star nut, brake adaptor and base plate the fork is a svelte 850g. The Hodag tire mounts up tubeless super easy on the Jackalope wheel. Nice light combination! The wheel with tape and valve is 1290g, rim is have a broad 75 internal width. The Hodag tire is 1190g, measures just shy of 4 inches mounted up. Wheel and tire are the absolute easiest to get set tubeless of any tire/rim combo I've dealt with. This wheel set up tubeless in one quick snap and doesn't need sealant to do it.
Half dozen rides on it (less than 50 miles total), the nubbins are still on the tire.
Plenty of details on the wheel/tire in the review on mtbr
