Acme is committed to the concept of manufacturing our bushings without a counterbore. We believe this produces a better, longer lasting and more versatile bushing (especially if you require modified or special bushings). Even though No-Counterbore bushings are more difficult and costly to produce, because close tolerances are required the full length of the bushing, No-Counterbore Bushings Are Standard With ACME! Counterbored bushings will be supplied only upon special request.
