ISUZU Connecting Rods

Isuzu diesels are the default choice for light and medium trucks, forklifts, generator sets and small excavators, so the rods in this category are usually bought by fleet workshops and parts traders rather than by retail customers. Most enquiries arrive with a number such as 1-12230104-1 or 8-97062-300 already in hand, taken from a parts book or from the rod still sitting in the engine.

Our Isuzu range covers the 4BD1, 6BD1 and 6BB1 engines, the 4JB1, 4JB1T, 4JA1, 4JG2 and C240 units, the 4BE1 and 4BC2, the turbocharged 4HF1, 4HG1 and 4HJ1, the 4JH1 and 4JK1 diesels, the 4JJ1 common rail family, the 4LE1 and 4LE2 engines used in small excavators, and the heavier 6BG1, 6HH1, 6HE1, 4HK1 and 4HE1 units. Reference numbers shown on the product pages include 1-12230104-1 and 1-12230095-1 for the 4BD1 and 6BD1, 8-94329-692-0 for the 4JB1, 8-97062-300 and 8-97062-300-0 for the 4JB1T and 4JG2, 8-97135032-0 for the 4HF1, 4HG1 and 4HJ1, 8-97165301-1 and 8-97352-890-1 for the 4JH1 and 4JK1, 1-12230129-1 for the 6BG1, 5-12230039-1 for the C240, and 8-97388921-2 for the 4JJ1.

Each rod is forged from alloy steel and machined to close limits, then checked dimensionally in batches so that bore sizes and centre-to-centre length stay consistent from one delivery to the next. Stock lines are supplied factory direct with no minimum order, so single samples and small trial lots are practical. Where the application is unclear, send your VIN or engine code and we will verify the correct rod first.
