Description
If you’re building a high-revving street or strip setup, a 4.88 gear ratio transforms your power delivery by maximizing acceleration off the line and keeping engine RPM in the sweet spot through mid-range. This complete kit eliminates the guesswork of sourcing individual components—you get everything needed for a bolt-in installation on your GM 10-bolt rear end. Whether you’re chasing better 60-foot times or sharper throttle response, this ratio delivers the mechanical advantage serious builds demand.
