LS Engine Mounts and Frame Bracket Kit for 1988-1998 GM Trucks
For builders converting a 1988 to 1998 GM four wheel drive truck to LS power, the 1988-1998 GM Truck 4WD LS Engine Mounts and Frame Bracket Kit delivers the precise positioning needed to preserve driveline angles and minimize vibration. Crafted from precision welded American steel, the brackets deliver exact engine placement within the factory chassis rails to maintain reliable torque transfer under both highway cruising and off road conditions. Complete with detailed instructions and every mounting fastener, this setup streamlines the swap process so shops and home builders can move quickly past trial and error. Heavy gauge American steel resists fatigue and flex so engine support remains consistent under sustained torque and varying chassis movement.
Precision Engine Alignment for Steady Driveline Angles
The custom-fit brackets in this kit position the LS engine with exact alignment inside 1988–1998 GM 4WD frames, eliminating guesswork and excessive shimming. By preserving correct driveline angles, the mounts reduce stress on universal joints and prevent early wear under load. Builders will notice less vibration through full suspension travel, whether accelerating on pavement or navigating uneven terrain. This level of accuracy ensures consistent torque transfer and maintains factory chassis dynamics throughout daily driving and trail use.
Robust American Steel Bracket Construction
Crafted from heavy gauge American steel, the frame brackets and engine mounts resist flex and fatigue under sustained torque and chassis movement. Precision welding at each joint delivers uniform strength and minimizes the risk of crack formation when subjected to off-road impacts or highway loads. The solid build keeps the powerplant firmly in place, preserving frame rail integrity over time. Users can expect dependable support that stands up to repeated cycles of acceleration, braking and suspension articulation.
All-Inclusive Installation Package for Swift Assembly
Designed as a complete bolt-on solution, this kit arrives with every bracket piece, mounting bolt and clear set of instructions needed for a straightforward swap. Step-by-step guidance streamlines the process, reducing reliance on specialty tools or extra fabrication. Whether tackling a first build or fitting multiple trucks in a shop environment, installers will appreciate the organized hardware and labeled mounting points. The result is a faster, more predictable installation that gets your LS-powered truck back on the road without delays.
