Industrial EX4617 & EX4617-1 Oil Cooler Bracket

The Humvee-compatible oil cooler mounting brackets for the M1113, M1114, M1151, and M1152 family come as two mirrored parts: EX4617 (left-hand) and EX4617-1 (right-hand). They attach to the engine accessory mounting points to secure and align the engine oil cooler and its associated lines within the engine bay, helping maintain proper routing and clearance for hoses and fittings. In Humvee parts catalogs these items are listed as BRACKET, OIL COOLER with NSN equivalents 5342-01-475-6643 for EX4617 and 5342-01-475-6655 for EX4617-1, and they appear in 12K-series diagrams as the dedicated oil cooler brackets. Alternate part numbers include 6501180, and the EX4617/EX4617-1 combination is documented across multiple vendors, including Midwest Military Equipment and Royal Equipment, with listings also appearing on secondary marketplaces like eBay. These brackets are commonly sold as Humvee replacement parts for restoration or maintenance of the M1113/M1114/M1151/M1152 platforms; confirm the exact left- or right-hand orientation and mounting hardware required for your chassis before ordering to avoid fit issues.
