MuscleRods LT Engine Swap Kit for 1988-1998 Chevy/GMC C1500 and 1992-1999 Tahoe/Yukon 2WD
When you’re fitting an LT V8 into a 1988-1998 Chevy or GMC C1500 or 1992-1999 Tahoe and Yukon 2WD, delivering reliable fuel flow can make or break your project. MuscleRods engineered the 340 LPH Fuel Pump and Fitting Kit to deliver a true bolt-on fit within the factory tank, providing the high volume required for LT series engines while preserving original underbody clearances. A matched pressure regulator and stainless steel fittings maintain consistent pressure during sustained throttle openings and resist corrosion under constant vibration. With dedicated mounting brackets and plug in wiring harnesses, this solution eliminates line cutting and speeds up installation without complex modifications.
Precision Crossmember and Drivetrain Alignment for LT Conversions
The included transmission crossmember anchors the engine and transmission in a position that mirrors factory geometry, preserving the optimal driveline angle. Maintaining this angle is essential to reduce vibrations and extend the service life of u joint assemblies. Installers will appreciate that no floor tunnel modifications are necessary for common transmissions such as the 4L60E and 4L80E, while the design also supports the 6L90E and T56 with minimal alterations. The robust design accounts for factory fuel and brake lines, preserving underbody clearances and avoiding interference with chassis components. By keeping the driveline components spinning true under load, this solution prevents premature wear and enhances smooth operation across the rev range.
Integrated Mounting System Simplifies Engine Installation
This kit comes complete with engine mounts and frame mounts precisely engineered to work together with the crossmember, eliminating guesswork during setup. Each bracket installs directly onto factory frame rails and aligns with LT engine main bolt bosses, enabling a true direct fit. Mount bosses are machined to tight tolerances to minimize alignment adjustments and deliver consistent fit across multiple chassis. By unifying engine and transmission mounts in a single package, installers avoid sourcing multiple aftermarket parts and reduce the risk of mismatched components. This installation strategy streamlines labor and ensures consistent positioning for reliable operation on and off road.
Optimized Oil Pan Clearance for Extended Sump Applications
A key consideration for OBS GM truck conversions is sump clearance, and this kit is fully compatible with extended sump pans designed for LT engines. The crossmember and mounts clear the deeper pan profile, preventing potential interference that can lead to leaks or impact damage. In tandem with a cast aluminum pan kit, this layout maintains proper oil pickup even under hard acceleration or steep inclines. By maintaining factory ground clearance, the combined pan and mount arrangement supports both street and light off road use without risk of bottoming out. Proper oil control helps safeguard against starvation and keeps engine bearings lubricated under dynamic driving conditions.
Domestic Manufacturing and Quality Assurance
All components of this engine swap kit are designed and produced in the United States, enabling tight quality control at every stage of fabrication. This local production allows for inspection of welds, bolt tolerances, and fitment in real time, ensuring that each piece meets strict performance standards. Sourcing domestically also reduces lead times and logistical complexity, so kits arrive ready for installation. In addition, domestic manufacturing fosters closer collaboration with engineering teams to refine designs based on installer feedback, resulting in continuous product improvement. The result is a robust assembly that installers can trust to perform consistently in harsh driving environments.
