This .375-inch transmission spacer plate can be used on Tremec T-56, TR6060, & the T56 Magnum transmissions and is constructed of 6061 T-6 Aluminum. The RM-193 fits between the Bellhousing and Transmission to adjust where the input shaft falls for engines where the crank does not have enough depth or more clearance for certain clutch/flywheel setups or throwout/release bearings (ideal for some pressure plate styles or multi-plate clutch assemblies.)

Longer transmission dowel pins and bolts are included. Spacer is made out of 6061-T6 Aluminum.

If installing a T-56 to L83-L84 Gen V GM Engine, we already provide a kit for this swap in Lakewood Transmission Installation Kit #50375 that uses the proper plate and necessary hardware.

Information on choosing the proper pilot bearing for custom setups that may be useful on LS Swaps:

There are three different LS pilot bearings, each with a different outside diameter. The size you need will depend on the distance that your transmission input shaft protrudes past the front of the bellhousing.

Small pilot bearing (1.094 inch) - Typically used with GM LS1-powered vehicles from 1998 to 2002. Medium pilot bearing (1.652 inch) - Typically used with GM LS3, LSA, LSX, and LS9-powered vehicles from 2003 to 2012.

Oversize pilot bearing (1.705 inch) - Can be used with some aftermarket crankshafts and GM crate engines where the crankshaft pilot bearing bore is oversized.

Important safety notes

• Use a straight edge or yardstick to measure the distance that your transmission input shaft protrudes past the front of the bell housing. -If the measurement is between 3/4 and 1 inch (19mm and 25.4mm), use the small diameter (1.094-inch) pilot bearing. -If the measurement is between 1/4 and 3/8 inch (6.3mm and 9.5mm), test fit the medium outside diameter (1.652-inch)pilot bearing. The bearing should be a slight press fit into the crankshaft. -If the medium diameter bearing is a loose fit, please use the large outside diameter (1.705-inch) bearing for a slight press fit into the crankshaft.
• Remove the old pilot bearing using a mechanical pilot bearing puller. Do not use a hydraulic method to remove the old bearing. -Clean the crankshaft pilot bearing bore with a clean rag. -Install the new pilot bearing into the crankshaft by driving or pressing on the outermost part of the bearing only. The bearing must be straight and fully seated into the crankshaft. Do not force the installation. -Once the bearing is installed, spin the inner portion of the bearing to make sure it rotates freely and smoothly.
• Do not move or disturb the press-in oil plug deep inside the crankshaft flange. -Do not use a hydraulic method to push-out or remove the old pilot bearing. -Be sure to install the new pilot bearing into the crankshaft by driving or pressing on the outermost part of the bearing only. The bearing must be straight and fully seated into the crankshaft. Do not force the installation.

Associated Comments:

If installing a T-56 to L83-L84, we already provide a kit for this swap in Lakewood Transmission Installation Kit #50375. When reinstalling dowel pins, use a small amount of oil/grease to install into a clean, rust-free hole. Re-torque to factory specs.
