MuscleRods LS Engine Swap Kit for 1982-2005 S-Series Blazer/Jimmy 2WD
If you plan an LS powerplant swap into a 1982 through 2005 S Series Blazer or Jimmy two wheel drive, this LS conversion kit delivers a direct fit solution that holds the engine at the correct angle for smooth operation. Machined motor and frame mounts lock the powerplant in place to minimize driveline shudder under load. The included crossmember accepts T56 4L60E and 4L80E transmissions without floor modifications while preserving full LH8 oil pan clearance for dependable oil pickup. Built in the USA by MuscleRods, this kit streamlines assembly and maintains belt alignment for Corvette style accessory drives without custom work.
Precision Engine and Frame Mounts for Smooth Operation
The conversion kit's motor and frame brackets are machined to exact tolerances, anchoring the LS powerplant at the factory-recommended angle to eliminate vibration under load. By securing the engine to the original S-Series rails, these mounts minimize driveline shudder and reduce stress on transmission components. This exacting fit delivers a comfortable ride and extends drivetrain life by preventing misalignment. Installation is streamlined with direct fit attachments, so no custom welding or bracket fabrication is needed.
Adaptable Crossmember for Multiple Transmission Types
The included crossmember accepts T56, 4L60E, and 4L80E transmissions without requiring tunnel modifications, preserving interior structure and panel alignment. Constructed from reinforced steel and designed for a bolt in installation, it maintains chassis rigidity even under high torque. For other transmission options a simple flattening of the pinch seam provides clearance, making this crossmember a versatile solution for diverse build plans. Precise hole placement ensures quick alignment with factory mounting points and reliable support during spirited driving.
Engine Bay Clearance for LH8 Oil Pan and Accessory Drives
This kit is engineered to clear the LH8 oil pan, safeguarding full sump capacity and ensuring reliable oil pickup without risk of contact or leaks. It also integrates Corvette balancer and water pump assemblies with specially sized brackets that preserve belt alignment in the confined engine bay. By addressing these clearance challenges up front, the design eliminates the need for extensive cutting or custom trimming. The outcome is a robust oiling system and accessory drive that perform consistently in daily use or spirited runs.
