Text excerpt from the catalog:
These Primo offset front pulley inserts allow custom bike builders the freedom to offset the transmission allowing the use of a wider rear wheel-tire assembly. There are two different insert styles available, a 2 1/2" diameter insert to fit Primo Brute III 1 3/4" and early style Brute IV 3" belt pulleys, the other a 3 1/2" diameter insert that fits late style Brute IV 3" wide belt pulleys. All inserts come with 5 countersunk screws and 2 dowel pins. You will need to select an outside guide, an insert and corresponding motor nut and the special washer.
