Stainless Steel Flexplate Adapter Spacer For GM TH350 TH400 LS1 LS2 LS3 LS6 5.3 6.0 LS7

When dropping an older automatic gearbox into an LS-powered project, the offset between the torque converter and factory curved flexplate often causes dangerous vibration or premature bearing wear. This stainless steel adapter spacer eliminates that guesswork by centering the converter nose precisely against your flywheel. You gain clean rotational balance and reliable mounting clearance without drilling new holes or buying an expensive replacement bellhousing.

Benefits & Practical Tips

• Wide Transmission Match Bridges the gap for TH350, TH400, 2004R, 700R4, 4L60, 4L60E, and 4L80E units.
• Fast Swap Ready Slips directly onto your LS or LT motor block to replace tedious custom fabrication.
• Fit Check Tip Skip this spacer entirely if you are working on a 1999–2000 6.0L engine, as that variant aligns natively.

Specifications

• Construction Machined from tough stainless steel to resist torsion stress and track heat during heavy loads.
• Engine Coverage Calibrated for Gen III, IV, and V LS/LT platforms built between 1998 and 2004, covering LS1, LT1, LS2, LS3, LS6, LQ4, and LS7 configurations.
• Primary Function Corrects converter-to-flexplate alignment on curved flywheels for cross-era transmission conversions.

Package Includes

• 1 x Flexplate Adapter Spacer
