GM Connecting Rods

GM's engine range runs from three-cylinder city cars through 1.5 and 1.6 litre family sedans to 2.4 litre Ecotec fours and the 3.6 and 5.3 litre units used in larger Buick, Chevrolet and GMC models, so this category is organised around engine codes rather than a single platform. The rods here cover B10, B12, B15D, F16D3, L3G, LB8 and LW9, the LE5 and LE9 Ecotec family, and the 3.7 litre H3 and H3T applications.

Common fits include the Buick GL8 and Regal, Chevrolet Malibu, Equinox, Cobalt, Spark and Sail, and the GMC Terrain. Matching numbers listed on the product pages include 24509040, 12649190, 12663617, 24512528, 12613195, 25408535 and 12590584, with 25187599 for B15D and 25192178 for the 1.0 litre three-cylinder B10; the 2.4 litre Ecotec rods reference 12654958, 12598216 and 12611360.

Every rod is forged from alloy steel and precision machined, with dimensional checks performed batch by batch so that big-end bore, small-end bore and centre-to-centre length remain consistent from order to order. Stock models carry no hard minimum order quantity, so trial lots and sample orders are welcome. If you are unsure which code applies, send the engine number or the OEM number from the old rod and we will confirm the match before you buy.
