Aluminum gearbox adapter plate designed to simplify gearbox installation as much as possible, eliminating radical measures such as cutting off the entire bellhousing – only the starter motor pocket needs to be prepared. Custom flywheels dedicated to PMC Motorsport adapters are made of aluminum with a replaceable friction surface, checked and balanced prior to shipping, and equipped with a pilot bearing that supports the transmission input shaft and minimizes vibration. Flywheel designed for a 240 mm pressure plate (GS5-39DZ / GS6-53DZ / BZ BMW OE). Flywheel weight: 6.0 kg (13.23 lbs), adapter thickness: 35 mm (1.37").

Additional information
PMC Motorsport parts are intended for motorsport use on closed race circuits.
These parts are designed to be installed by qualified professionals experienced in engine swaps and automotive conversions – in proper workshop facilities and with suitable tools.
The adapter installation manual provides only the fundamental guidelines required to physically join the engine and transmission outside the vehicle chassis.
Depending on the specific chassis, additional modifications may be necessary, including: adapting engine mounts, transmission crossmembers and bushings, clearance on the firewall, transmission tunnel modifications, propshaft length adjustments, etc.
We manufacture our adapters using fully recyclable materials.
Installation manual
The custom flywheel requires an automatic version flexplate (starter ring gear) from a Chevrolet LS OE 12654640, 12553054, 12563136, 12580709, 12602448, 12606620, or 12637677 (not included in the kit). Bolt the flywheel to the crankshaft using the supplied bolts torqued to 80 Nm (59 lb⋅ft) with medium threadlocker applied. To complete the adapter installation, the original Chevrolet LS starter motor (OE, not included in the kit) must be used.
Frequently Asked Questions
Which engines does this adapter fit?
GM Chevrolet V8 Small Block LS family engines: LS1 (5.7), LS2 (6.0), LS3 (6.2), LS6 (5.7), LS7 (7.0), and LSX (6-bolt crankshaft), as well as Vortec 4800, 5300, 6000 (VortecMAX), and 6200 engines.
Which gearboxes does this adapter fit?
5-speed manual ZF GS5-39DZ transmissions from BMW M57 diesel applications in variants THBA, THBC, THBG, THBK, and THBM (E39 525d / 530d, E46 330d). The transmission features a 28x35-10N spline.
Do I need to cut the gearbox bellhousing?
No. The adapter is engineered to eliminate cutting off the bellhousing – only an opening for the starter motor needs to be prepared.
What additional parts are required for installation?
An automatic transmission flexplate (starter ring gear) from a Chevrolet LS OE 12654640, 12553054, 12563136, 12580709, 12602448, 12606620, or 12637677. You will also need: a 240 mm clutch pressure plate and clutch disc, release bearing, clutch fork, and clutch slave cylinder dedicated to your specific gearbox, as well as an original Chevrolet LS starter motor (OE). These parts are not included in the kit.
Which clutch pressure plate fits the PMC flywheel?
A 240 mm (9.45") BMW OE type pressure plate – from BMW M57 (including the stock GS5-39DZ pressure plate) / M57N / M57N2 / N54 / B58 / E46 M3, Sachs XTend 3000 951 877 (BMW M57), or Sachs Performance 883082.001243. ACT / Spec / Tanaci clutches are also commonly used – any aftermarket pressure plate must match the BMW OE flywheel bolt pattern (M57 / M57N / M57N2 / N54 / B58). For the GS5-39DZ gearbox, use a 240 mm clutch disc with a 28x35-10N spline, a matching release bearing assembly, and a slave cylinder.
Which starter motor should be used?
The original Chevrolet LS starter motor (OE). The starter motor is not included in the kit.
What is included in the kit?
An aluminum gearbox adapter plate with mounting hardware, custom PMC Motorsport aluminum flywheel with replaceable friction surface and pilot bearing (6.0 kg / 13.23 lbs), crankshaft bolts, pressure plate bolts, and a clutch pivot pin – replacement for BMW OE 21 51 1 223 328. The clutch disc, pressure plate, release bearing, clutch fork, and clutch slave cylinder are not included and must be sourced to match your transmission.
Can I purchase only the adapter plate or only the flywheel?
Yes. Every component of the kit is available individually.
Does the price include customs duty for shipments outside the European Union?
No. The product price and shipping quote do not include import customs duties, tariffs, or local fees that may apply in the recipient's country.
Can I purchase with 0% VAT?
Yes, if you are a registered B2B customer outside of Poland with an active EU VAT number (validated via VIES) or if placing an export order outside the EU.
Is the included manual sufficient to complete the installation?
The manual covers mating the engine to the transmission outside the vehicle chassis. Depending on your car chassis, additional custom modifications may be required: engine mounts, crossmembers, firewall clearance, transmission tunnel modifications, driveshaft sizing. We strongly recommend professional installation.
Please note that a lightweight single-mass flywheel delivers uncompromising throttle response by eliminating factory dual-mass damping components. This results in a more direct drivetrain connection, which can naturally increase the audible operating noises of the transmission gears. This is a normal and sought-after characteristic in performance and motorsport applications resulting from the rigid mechanical connection between the engine and the drivetrain.
