Before You Buy Drivetrain Upgrades
Why does the drivetrain matter on a performance build?
Engine power is irrelevant if it can't reach the road efficiently. The drivetrain — differential, clutch, and driveshaft — is the mechanical chain between your engine output and wheel traction. A limited slip differential alone can transform how a high-power build feels on the street, making every other modification more usable. An upgraded clutch prevents the stock unit from becoming the weakest link in a Stage 2 or higher build.
Upgrade priority order
(1) Limited slip differential — the highest single-component traction gain on any open-diff car. (2) Performance clutch — essential for manual builds at Stage 2+ power. (3) 1-piece aluminum driveshaft — for high-power builds experiencing vibration or driveline stress. (4) Short-throw shifter — quality-of-life improvement for manual builds, should pair with clutch upgrade.
Drivetrain and tires work together
An LSD only works as well as the tires under it. Running performance street tires amplifies LSD traction gains significantly. The Charger Scat Pack tire guide covers the compound and sizing decisions that maximize what your LSD can deliver on the LC platform. Planning a full drivetrain swap? Use our engine swap finder to match donor engines to compatible chassis before you buy.
Common mistakes to avoid
- Skipping clutch break-in after installation — kills the disc within 500 miles
- Ordering a clutch-pack LSD without buying the correct friction modifier additive
- Installing a 2-disc clutch on a car that won't be tuned — too aggressive for stock engagement
- Ignoring driveshaft vibration on high-power builds — it's a warning, not a quirk
