Chevy Transmission Space r Shim .25in

The Chevy Transmission Space r Shim .25in from ICT Billet is a precision-engineered bellhousing plate designed for classic and modern Chevy V8 engine swaps using Powerglide transmissions. This quarter-inch aluminum spacer solves a common fitment challenge: when retrofitting a Powerglide into vehicles with tight engine bay geometry, transmission-to-block clearance becomes critical. Whether you're building a street rod, restomod, or vintage race car, this shim ensures proper spacing without compromising structural integrity or creating binding issues during installation.

Machined from high-grade aluminum and finished in natural mill appearance, the Chevy Transmission Space r Shim .25in measures 12.4 x 17.9 inches—substantial enough to span the bellhousing mounting surface while maintaining a lightweight footprint at just 0.75 lbs. The 0.25-inch thickness provides the exact offset needed to move the transmission rearward and prevent interference with the engine block, oil pan, or motor mounts. ICT Billet's reputation for precision billet work means this plate is flat, deburred, and ready for bolt-on installation without secondary machining.

This shim is essential for engine swap enthusiasts running small-block or big-block Chevy V8s with Powerglide transmissions in vehicles originally designed for different drivetrain configurations. Installation is straightforward: position the plate between the transmission bellhousing and engine block, then secure it using existing bolt holes. Verify clearance between the transmission tailshaft and driveline components before final torque-down. Compatible with all Chevy V8 engine families and standard Powerglide mounting patterns, this shim transforms a problematic fit into a professional, reliable installation.
