Precise LS Flexplate Spacer with OEM Grade Bolts

Optimized for 6.0L LS to 4L80E swaps, the CLEARANCE-LS Flexplate Spacer delivers OEM grade durability and precise fit with genuine GM OEM materials and factory spec level accuracy. Precision machining and supplied mounting bolts accelerate installation and guarantee smooth integration of non LS transmissions for dependable, hassle free operation. Integrated alignment minimizes install time and removes the need for extras, ensuring a quick and accurate swap on the first try.

LS Flexplate Spacer with Bolts for Proper Engine Swap Clearances

On 6.0L LS to 4L80E conversions, the CLEARANCE-LS Flexplate Spacer with Bolts ensures precise spacing between the flexplate and converter housing to prevent clutch interference. Crafted from genuine NOS GM OEM materials, it matches factory tolerances for concentricity and resists fatigue under heavy torque loads typical of a 6.0L powerplant. With all mounting bolts included and an exact thickness that removes the need for shims, installation takes minutes and delivers consistent crank control without vibration or noise. Its precise dimensions also remove guesswork when adapting early transmissions not originally designed for LS engines and preserve starter alignment for smooth, reliable engagement.

Genuine OEM Material for Unwavering Torque Durability

The CLEARANCE-LS spacer is crafted from genuine NOS GM OEM material, matching the original casting and alloy composition used by the factory. This precise metallurgy delivers superior resistance to warping under the high torque output of a 6.0L LS engine, preventing deformation that can compromise fit. In contrast to generic aftermarket options, it avoids material inconsistencies that can introduce stress points and lead to premature fatigue. Maintaining constant concentricity with the crank flange also helps control vibration, safeguarding bearings and transmission components. Technicians gain confidence knowing this spacer meets the same rigorous standards applied on the assembly line.

Precision Machining for Exact LS 6.0L to 4L80E Fitment

Each spacer undergoes precision machining to hold tight tolerances on bore diameter and overall thickness, eliminating clutch interference between the flexplate and converter housing. Its concentric design ensures the flexplate remains perfectly centered on the crank flange, removing the need for trial fits or shims. By matching factory clearance, it delivers smooth crank rotation and reliable starter engagement every time. The controlled tolerance also prevents uneven wear on clutch discs and transmission seal surfaces, extending component life. This exact fit mirrors GM's original specifications to preserve engine balance and drivetrain harmony.

Comprehensive Bolt Set Tailored for Accurate Installation

Every package includes a full complement of mounting bolts selected for the exact thread pitch and required tensile strength of the LS to 4L80E interface. These fasteners feature a corrosion resistant finish that holds specified torque over repeated thermal cycles and road conditions. By supplying all the hardware, the spacer kit removes the time spent sourcing and testing individual bolts, cutting installation steps down to minutes. With the correct bolts on hand, builders can adhere precisely to torque specs and reduce the risk of fastener loosening in service. This integrated approach streamlines any conversion project and ensures long term reliability.

Streamlined Integration for Early Non LS Transmissions

Early transmission housings were not designed with modern LS engines in mind, often resulting in contact between the flexplate and converter housing. The CLEARANCE-LS spacer solves this by introducing the exact gap required for a 6.0L block and 4L80E transmission pairing. Builders avoid the mess of stacking unreliable shims or fabricating custom adapters, preserving proper starter alignment for smooth engagement and disengagement. By setting the correct separation from the outset, it reduces downtime and keeps conversion projects on schedule. The result is a precise, factory style fit that performs consistently under real world driving conditions.

This spacer delivers a precision fit and dependable operation for any LS to 4L80E conversion.
