Industrial Injection 89-93 Dodge 4BT Mahle Piston .040 Oversized w/ Rings / Wristpins / Clips

If you're rebuilding the engine in your 1989-1993 Dodge with a 4BT engine, this Mahle piston set from Industrial Injection is a solid option. This set includes four pistons that are .040 inches larger than stock, along with matching rings, wristpins, and clips. Using oversized pistons is a common practice when the cylinder walls have been worn beyond the limits for standard-sized pistons, or if they've been bored out to a larger size to restore proper compression and sealing.

Mahle is a well-known name in engine components, and these pistons are built to meet the demands of the 4BT engine. They are cast from a durable aluminum alloy, designed to handle the stresses of diesel operation. The .040 inch oversize means these are intended for engines that have already been bored out to this specific dimension, ensuring a snug fit within the cylinders. This set comes complete with all the necessary rings, wristpins, and clips to get your engine reassembled, making it a convenient choice for a comprehensive rebuild.

When installing these pistons, ensure your cylinder bores are properly cleaned and measured to confirm they are within the specified tolerance for a .040 inch oversize piston. It's also a good idea to have the connecting rods checked and balanced if you're doing a full engine overhaul. This set is designed for a direct fit into the specified Dodge 4BT applications, simplifying the installation process for a mechanic or a dedicated DIYer.
