The compression limiter includes a tubular bushing extending from a first end to a second end. The tubular bushing includes an exterior surface and an interior surface extending from the first end to the second end to define an aperture through the tubular bushing. The compression limiter also includes one or more detents formed in at least one of the first end of the bushing and/or the second end of the bushing. In some examples, the compression limiter includes a first pair of the detents formed in the first end and a second pair of the detents formed in the second end. ## Claims ### Claim 1 A compression limiter comprising: a tubular bushing extending from a first end to a second end, the tubular bushing including a cylindrical exterior surface and a cylindrical interior surface extending from the first end to the second end to define an aperture; and one or more detents formed in at least one of the first end of the bushing and/or the second end of the bushing; wherein each of the one or more detents includes a cylindrical end and a pair of sidewalls connecting the cylindrical end to one of the first end or the second end of the bushing; wherein a distance from the cylindrical end to the one of the first end or the second end defines a depth of the detent and a distance from a first one of the sidewalls to a second one of sidewalls defines a width of the detent that is equal to the depth of the detent. ### Claim 2 (depends on 1) The compression limiter of claim 1, wherein the interior surface defines an inside diameter of the bushing and the exterior surface defines an outside diameter of the bushing. ### Claim 3 (depends on 1) The compression limiter of claim 1, wherein each of the one or more detents extends through the bushing from the exterior surface to the interior surface. ### Claim 4 (depends on 1) The compression limiter of claim 1, wherein the one or more detents includes a pair of detents formed in the first end of the bushing. ### Claim 5 (depends on 4) The compression limiter of claim 4, wherein the one or more detents further includes a second pair of detents formed in the second end of the bushing. ### Claim 6 (depends on 1) The compression limiter of claim 1, wherein the bushing includes a chamfered edge at an intersection of the exterior surface with at least one of the first end and the second end. ### Claim 7 (depends on 1) The compression limiter of claim 1, wherein the bushing includes a metal alloy. ### Claim 8 (depends on 7) The compression limiter of claim 7, wherein the bushing is zinc plated. ### Claim 9 A compression limiter comprising: a tubular bushing extending from a first end to a second end, the tubular bushing including a cylindrical exterior surface and a cylindrical interior surface extending from the first end to the second end to define an aperture; and a plurality of detents including a first detent formed in the first end of the bushing and a second detent formed in the second end of the bushing; wherein each detent of the plurality of the detents includes a cylindrical end and a pair of sidewalls connecting the cylindrical end to one of the first end or the second end of the bushing; wherein a distance from the cylindrical end to the one of the first end or the second end defines a depth of the detent and a distance from a first one of the sidewalls to a second one of sidewalls defines a width of the detent that is equal to the depth of the detent. ### Claim 10 (depends on 9) The compression limiter of claim 9, wherein the interior surface defines an inside diameter of the bushing and the exterior surface defines an outside diameter of the bushing. ### Claim 11 (depends on 9) The compression limiter of claim 9, wherein each of the first detent and the second detent extend through the bushing from the exterior surface to the interior surface. ### Claim 12 (depends on 9) The compression limiter of claim 9, wherein the plurality of detents further includes a third detent formed in the first end of the bushing and a fourth detent formed in the second end of the bushing. ### Claim 13 (depends on 12) The compression limiter of claim 12, wherein the first detent and the third detent are diametrically opposed to one another. ### Claim 14 (depends on 9) The compression limiter of claim 9, wherein the bushing includes a chamfered edge at an intersection of the exterior surface with at least one of the first end and the second end. ### Claim 15 (depends on 9) The compression limiter of claim 9, wherein the bushing includes a metal alloy. ### Claim 16 (depends on 15) The compression limiter of claim 15, wherein the bushing is zinc plated.
