LS1 into 2WD S-10 Motor Mount Kit

The TRANS-DAPT LS1 into 2WD S-10 Motor Mount Kit (Part #4516) is a bolt-on steel mounting solution engineered to adapt LS-series engines into 2WD Chevrolet S-10 compact truck platforms originally equipped with 4.3L powerplants. This kit eliminates the guesswork in one of the most critical steps of an LS engine swap—solid engine-to-frame interface—and provides the mechanical foundation upon which all other drivetrain systems depend.

The mounting kit employs steel construction throughout, delivering the rigidity required to manage engine torque and vibration loads without deflection or stress fracture over extended use. Bolt-on design means no welding, no fabrication, and faster installation for shops and enthusiasts executing LS swaps on a timeline. The kit is engineered specifically for 2WD S-10 chassis geometry—a critical distinction, as suspension and frame rail spacing differs measurably between 2WD and 4WD variants. Proper engine location affects transmission alignment, driveshaft angles, and cooling flow, all of which depend on accurate positioning from the start.

This kit addresses the needs of compact truck builders stepping up from the 4.3L to modern LS power (5.3L, 5.7L, 6.0L, or earlier generation 5.3L variants). The LS platform is known for high-output-per-displacement efficiency and parts availability, making it the engine of choice for S-10 restorations and performance builds. Proper engine mounting is non-negotiable; inadequate support creates cascading problems in driveline harmonics and frame stress distribution that surface as vibration, noise, and premature component wear.

TRANS-DAPT is recognized in the powertrain adapter and mounting space for detailed engineering specific to model-year and chassis combinations. This kit reflects that focus—it is not a universal bracket adapted from another platform, but a purpose-built solution for the LS-to-S10 conversion sequence. Weighing 10.55 lbs, the kit is packaged for efficient shipment and handling during installation.
