Flexplate Spacer Shims GM 86-96 kit

The Quick Time Flexplate Spacer Shims GM 86-96 kit is a precision engine component designed to adjust flexplate-to-converter spacing on General Motors 4.3L, 5.0L, 5.7L, and LS-series engines from 1986 through 1996. Proper flexplate spacing is critical for smooth torque converter engagement, transmission longevity, and preventing converter-to-bellhousing contact that can result in catastrophic damage during high-performance operation or engine rebuilds.

This kit includes five precision-machined steel shims with zinc-oxide coating: 0.030", 0.036", 0.048", 0.060", and 0.075" thickness options. Each shim features a 4.600" outer diameter and 2.066" inner center hole, engineered to match factory GM flexplate and bell housing specifications exactly. The multiple thickness options allow installers to dial in exact clearance during engine installation, transmission swap, or converter replacement—a critical variable that cannot be ignored when changing transmission types, flexplates, or converters.

This flexplate spacer kit is essential for engine builders, transmission specialists, and performance enthusiasts executing LS swaps into GM vehicles, upgrading transmissions, or rebuilding engines where original spacing tolerances must be restored. The shim-stack approach lets technicians fine-tune clearance to factory specs without custom machining, reducing installation time and ensuring proper converter function across different transmission combinations.

Quick Time Manufacturing is recognized for precision drivetrain components, and this spacer kit reflects that focus on OEM-correct dimensions and repeatability. Installers working on 1986–1996 GM applications—whether small-block Chevy, big-block, or modern LS powerplants retrofitted into classic platforms—rely on accurate spacing to prevent converter noise, slippage, and transmission damage.
