LS1 into 2WD S-10 Motor Mount Kit

The TRANS-DAPT LS1 into 2WD S-10 Motor Mount Kit (Part #4516) is purpose-built for serious S-10 enthusiasts planning an LS1 engine swap into second-generation, two-wheel-drive Chevrolet S-10 pickups. This kit addresses one of the most critical challenges in LS engine conversions: proper engine positioning and structural support within the original S-10 chassis. Whether you're building a street machine, weekend warrior, or weekend track truck, engine mounts are non-negotiable for vibration isolation, driveline alignment, and long-term powertrain durability.

This complete mount kit solves the dimensional mismatch between the LS1 block and the S-10's original engine bay architecture. TRANS-DAPT engineered precision-fit brackets and isolator mounts that maintain correct engine height, angle, and lateral spacing relative to the frame rails, transmission tunnel, and hood clearance. The kit ensures proper load distribution across existing frame attachment points, reducing stress concentration that leads to frame cracking or engine movement under acceleration. High-durometer rubber isolators dampen harmonics and vibration transfer to the chassis, preserving structural integrity and driver comfort during extended cruising or high-rpm driving sessions.

This kit is essential for S-10 owners committed to a comprehensive LS1 engine swap without welding, custom fabrication, or frame modification. Compatibility is limited to two-wheel-drive S-10 models (4WD versions have different frame geometry and require alternative solutions). Installation pairs seamlessly with complementary TRANS-DAPT products including transmission adapter kits, cooling system mounts, and accessory drive brackets. Proper installation—following torque specifications and using new fasteners—takes approximately 3–4 hours with basic hand tools and a floor jack.
