The 21-795-1000 is a Pure Drivetrain Solutions one-piece SUPER-FLEX flexplate built for Gen 3 Hemi V8 engines with a 131 tooth integral ring gear.
Which engines does this flexplate fit?This flexplate is designed for Gen 3 Hemi 5.7L, 6.1L, 6.2L, and 6.4L V8 engines used across Dodge, Jeep, and Ram vehicles.
Is this flexplate SFI certified?The flexplate is tested to 20,000 RPM, which exceeds SFI safety standard 29.2.
What material is the flexplate made from?It is machined from hand-selected aerospace grade alloy steel sourced from USA steel mills and put through a 3-stage heat treating process.
Does this flexplate work with multiple torque converter bolt patterns?Yes, the flexplate accommodates multiple torque converter bolt patterns for broad transmission compatibility.
Will this flexplate reduce rotating mass?Yes, lightening pockets are machined into the flexplate to reduce weight without sacrificing strength.
What finish does the flexplate have?The flexplate has a matte black finish with a laser etched logo.
Is professional installation recommended?Yes, flexplate installation involves engine and transmission separation and is recommended for an experienced installer or machine shop.
Does the 21-795-1000 require a spacer for installation?No, the 21-795-1000 is designed to bolt directly to the Gen 3 Hemi crankshaft flange without requiring a spacer.

Flex discs, also called guibo couplings, are the rubber-reinforced fabric driveshaft couplings used on rear-wheel-drive and all-wheel-drive vehicles with transaxle layouts to connect the driveshaft or propeller shaft to the transmission output flange, absorbing torsional vibration and minor angular misalignment between the gearbox and driveshaft while transmitting full drivetrain torque without the vibration penalty of rigid shaft coupling. These components are particularly common on BMW, Mercedes-Benz, Volvo, Porsche, and other European rear-wheel-drive platforms where the guibo design has been standard for decades, and worn flex discs are one of the most frequently overlooked causes of drivetrain vibration, clunking on throttle application, and accelerated universal joint wear on vehicles where the flex disc has hardened or cracked from age. Replacement with a quality rubber flex disc restores smooth power delivery and protects the driveshaft's universal joints from the shock load...

Flexplates are the thin stamped steel or billet aluminum rings that connect an automatic transmission-equipped engine's crankshaft to the torque converter, serving the dual function of providing the ring gear teeth that the starter motor engages for engine cranking and creating the flexible coupling between the rigid crankshaft flange and the torque converter's fluid-driven impeller housing. Unlike the flywheel used with manual transmissions, a flexplate is intentionally designed to flex slightly to absorb minor dimensional misalignment between the crankshaft centerline and the torque converter mounting face, preventing stress concentration at the crankshaft flange. High-performance SFI-certified flexplates are required by NHRA and IHRA for automatic transmission-equipped competition vehicles where the rotating assembly mass and launch forces exceed the safe limits of stock stamped steel flexplates. This collection covers replacement and performance flexplates for domestic and impor...
