The Corvette Comeback
In 1984 a new Corvette made 205 horsepower and showed its speed on a digital dash. By 2009 a Corvette made 638 horsepower and lapped the Nürburgring with exotic cars. Three generations did that work. We part out all three, and they make up the biggest shelf in our yard.
- 1C4 Corvette1984–1996 · 205–405 hp · ZR-1 with Lotus-designed LT5
- 2C5 Corvette1997–2004 · 345–405 hp · LS1 and LS6
- 3C6 Corvette2005–2013 · 400–638 hp · ZR1 claimed 205 mph
The theme: from malaise to world class
The Corvette came out of the 1970s heavy and down on power. Over the next three generations, Chevrolet rebuilt it piece by piece: a modern chassis, then a modern engine and architecture, then real supercar performance. Each step solved the last generation's biggest problem, which is also why parts rarely cross between them.
C4 Corvette
1984–1996
The C4 was so late that Chevrolet skipped the 1983 model year entirely and launched the new car early as a 1984. It was a clean-sheet design with a stiff new chassis and a digital LCD instrument cluster that looked like the future in 1984. Power started at 205 hp and climbed steadily through the L98 years, reaching 300 hp with the LT1 in 1992 and 330 hp with the 1996 LT4.
The headline was the ZR-1. After GM bought Lotus in 1986, Lotus helped design the 32-valve, quad-cam LT5, which Mercury Marine assembled in Stillwater, Oklahoma. It made 375 hp at launch and 405 hp from 1993. On March 1, 1990, a stock ZR-1 set a 24-hour world endurance record, averaging 175.885 mph. Only about 6,900 ZR-1s were built.
Owner's notes: On 1992–96 LT1 and LT4 cars, the Optispark ignition sits under the water pump, so a leaking pump can kill it; replace them together. Watch for head gasket and cooling-system wear on high-mileage cars. Fiberglass bumper covers in factory colors are some of our most-requested C4 parts. And if you own a ZR-1, know that its engine computer is no longer made new. A used unit from our ECU and module collection is the replacement.

C5 Corvette
1997–2004
The C5 is the generation that changed everything underneath. It debuted the all-aluminum LS1 V8, the engine family that went on to power half the swap projects in America. It used a hydroformed steel frame that was far stiffer than the C4's, and it moved the transmission to the rear axle, connected to the engine by a torque tube, for near-perfect weight balance.
The LS1 started at 345 hp. For 2001 the lighter, fixed-roof Z06 arrived with the LS6, making 385 hp and then 405 hp from 2002. The C5 also put the Corvette back in serious racing: the C5-R won Daytona outright in 2001 and took class wins at Le Mans. Built in Bowling Green, Kentucky, the C5 ran through 2004.
Owner's notes: The "Service Column Lock" no-start is the best-known C5 problem. Watch for ABS/traction module (EBCM) faults, a wobbling harmonic balancer, and noise from worn torque tube couplers. Some 2002–03 Z06 LS6 engines had valve spring concerns, so ask about the history. We list C5 modules and fuse boxes and suspension parts with their part numbers, plus hoods and panels in factory colors.

C6 Corvette
2005–2013
The C6 took the C5's foundation and sharpened it. It was shorter, with exposed headlamps for the first time since 1962, and launched with the 400-hp LS2, followed by the 430-hp LS3 in 2008. Then came the specials. The 2006 Z06 had a hand-built 7.0L LS7 making 505 hp. The 2009 ZR1, nicknamed "Blue Devil" in development, used the supercharged LS9 to make 638 hp, and Chevrolet claimed a 205-mph top speed.
The ZR1 also lapped the Nürburgring in 7:26.4, putting a Corvette among the world's fastest production cars. The last C6, a white 427 Convertible, rolled off the line on February 28, 2013.
Owner's notes: Valve-guide wear on LS7 engines (Z06 and 427) is the big one: have the heads checked or rebuilt. Check the harmonic balancer for slippage by marking it. 2005 cars were covered by a steering column lock recall. Electronic door releases and battery-tray corrosion are other common gripes. Wheels look similar across years but sizes and offsets vary, so match by part number, or grab a matched factory wheel set.

Where the Corvette went next
The C7 arrived for 2014, reviving the Stingray name with a 455-hp 6.2L LT1, and the C8 finally moved the engine behind the driver for 2020. But the C4, C5 and C6 are where most Corvette owners and builders live today, and where used OEM parts matter most.
