The WARN Premium Locking Hub is a no-compromise hub designed for the hardcore off-roader or truck owner who will accept nothing less than the industry standard in performance. The all-metal construction and ZA alloy dial ensure years of reliable functioning. This dial requires a full 9/10ths of a turn to ensure positive engagement of the inner drive gear to the clutch ring. To make sure they stay engaged, WARN Premium Hubs use a thick internal wave spring and heavy dial detents.• Heavy detents for positive engagement• Wave spring technology increases reliability over standard coil springs• All metal construction• ZA alloy dial with dual seals keeps contaminants out• Sold in pairsFitment1977-1986 Chevrolet K301988-1990 Chevrolet K35001987-1987 Chevrolet R301987-1988 Chevrolet V301989-1990 Chevrolet V35001990-1993 Dodge W2501990-1993 Dodge W3502000-2005 Ford Excursion1977-1996 Ford F-2501997-1997 Ford F-250 HD1999-2004 Ford F-250 Super Duty1978-1997 Ford F-3501999-2004 Ford F-350 Super Duty1977-1978 GMC K351979-1990 GMC K35001987-1987 GMC R35001987-1990 GMC V3500 Full 9/10ths of a turn ensures positive engagement of the inner drive gear Thick internal wave spring and heavy dial detents Sold in pairs | 38826 Premium Locking Hubs, 30-Spline
