Multi-Fit Frame LS Engine Mount Kit for 1973-1998 GM A, F, B Bodies & Trucks
Multi-Fit LS mounts are now available. These mounts are designed to be used with GM clamshell frame mounts and offer multiple choices for final positioning on the LS block. These mounts were designed to be used on chassis where a direct bolt-in kit is not available, but can be used on many different vehicles that use a GM clamshell mount setup.
Exact OEM Clamshell Frame Interface
By replicating the factory Chevrolet clamshell frame mount, this kit ensures the engine sits exactly where it was intended. That precise interface removes the need for custom brackets or spacers, preventing misalignment that can lead to premature wear on driveline components. With the mounting points keyed to OEM dimensions, installers gain confidence that the engine and transmission remain square to the chassis under load. This alignment fidelity reduces unwanted vibration and simplifies subsequent drivetrain hookups.
Robust Mild Steel Fabrication with Powder Coat Protection
Each mount is stamped from mild steel known for its excellent yield strength and resistance to bending under torque. After welding, the assemblies receive a uniform powder coat finish that guards against rust, chipping, and abrasion in harsh under-hood environments. The powder coat also provides a smooth surface that sheds debris and is easy to clean during routine maintenance. Together, the steel and finish deliver a durable mounting foundation designed to endure the stress cycles of daily driving and spirited use.
Seamless Integration with Sure-Fit Crossmember and Mid Length Headers
Engine placement is calibrated to work hand in glove with our Sure-Fit crossmember systems, ensuring consistent ground clearance and firewall setback. At the same time, the mounts accommodate mid length headers without interference, preserving optimal exhaust routing and flow characteristics. This unified approach eliminates the trial-and-error phase common to custom swaps and keeps installed components from rubbing or binding. The result is a cleaner engine bay and fewer fitment issues during assembly.
Broad Compatibility for GM Cars and Trucks
Designed and validated across 1973-1998 multiple GM platforms and full-size trucks, this kit covers the most popular chassis for LS conversions. One set of mounts addresses decades of model variations, dramatically cutting part selection complexity and installation time. Whether you're working on a Monte Carlo, Chevelle, Camaro, Caprice or C/K pickup, the same proven hardware delivers repeatable results. That multi-platform coverage minimizes inventory and offers a straightforward path to a reliable swap.
