Listing details to confirm

The listing combines configuration-specific claims: the selected style and size are 2 inch Forward Offset and 34 mm diameter, while other dimensions and weights describe different centerline heights or versions. The stated 4-3 oz range is unclear as written, and the listing does not confirm the centerline height for this selected configuration. Check the exact variant and fit before purchase. The lifetime guarantee is a manufacturer claim.
