Bassett's 15 x 8 spun shell beadlock wheel is the only IMCA legal beadlock utilizing 100% spun-form shells and rings. Spun-form shells and rings are stronger, lighter and have less runout than roll-formed beadlock wheels.
Another important feature of the Bassett beadlock is the stepped design of the two rings, which self-centers the tire and makes mounting a breeze. The Bassett beadlock also uses 18 high grade bolts, which clamps more consistently and prevents premature wear and air leaks.
