DescriptionSold as Pair. Unique per truck. – Lively & Responsive – Hand-poured into Custom-made molds – Super low-friction due to the reduced surface contact with the nose of the hanger – RipTide’s exclusive Internally Lubricated WFB Urethane in 96aRipTide Pivot Cups & Tubes are the result of two years of beta testing in every possible condition that Colorado’s high country can deliver. RipTide’s Pivots are specifically designed for each truck. We do not offer universal styles because of the compromises a universal pivot forces you to make and in some cases, we even offer both Tubes & Cups for the same truck. Both offer the smooth turning benefits of RipTide’s exclusive internally lubricated WFB Urethane in 96a, but the Tube offers even lower friction due to the reduced surface contact with the nose of the hanger.
