C5 C6 Corvette 3.90 Gears Motive Performance Ring & Pinion

If you’re looking to sharpen throttle response, improve acceleration, and get more out of your 1997–2004 C5 or 2005–2013 C6 Corvette, swapping to a 3.90 gear ratio is one of the most effective drivetrain upgrades you can make. The factory 3.42 ratio leaves performance on the table — the 3.90 closes that gap by keeping the engine deeper in its powerband through the gears, delivering a noticeably more aggressive and responsive driving experience on both the street and the track.While a few other manufacturers produce 3.90 ring and pinion sets for the C5 and C6 platform, Motive Gear is our recommended choice after years of hands-on experience in our shop. Competing options tend to cost more while delivering less — Motive Gear consistently offers the best combination of quality, durability, and value.Manufactured from 8620 alloy steel — the industry standard material for performance ring and pinion sets — this gear set is engineered for quiet, smooth operation despite the more aggressive ratio. No excessive gear whine, no compromise in refinement, just a direct confidence-inspiring upgrade that transforms how your Vette pulls through every gear.
