MUSCLE PERFORMANCE ’69 CAMARO
we learned that three important players in the hot rod industry—Chip Foose, Unique Performance and Year One—were coming together for a unique collaboration. Their combined goal was to build a limited-production-built car. Unique Performance already has just such a business, as it builds and sells its continuation Shelby Mustangs.

70 Years of Cool: The Tri-Five Chevy Turns Platinum
In 1955, Chevrolet didn’t just redesign a car—they ignited a movement. The Tri-Five Chevys (that’s shorthand for the 1955, 1956, and 1957 models) arrived like a thunderclap and never really left. These machines were leaner, lower, and louder—in both looks and performance—ushering in a new era of V8-powered excitement. The shoebox shape, the tailfins, the grille teeth…every detail had attitude. And the world noticed.

TPI: TODAY’S PERFORMANCE INCREASE
There are few modifications that can be made to an engine that can give both increased performance and better fuel economy. In these days of increased gasoline prices (nearly $4.50 per gallon), fuel mileage is an important consideration for vintage trucks that owners consider their daily drivers. For many reasons, vintage pickups are becoming not just weekend toys but also weekday workers. And one of the best ways to increase both performance and mileage is with an electronic fuel-injection system.

Built for the Street, Ready for Action
The McLeod RST clutch was designed for real-world performance — not dyno queens or trailer-only builds. It thrives in daily-driven cars that see boost, hard pulls, and aggressive driving, while still behaving in traffic. This twin disc clutch kit gives you the freedom to push your build without constantly worrying about slip or drivability issues.
Why the RST Hits the Sweet Spot
Race clutches can hold power, but they usually come with harsh engagement, heavy pedals, and zero forgiveness. The McLeod RST Twin Disc Clutch strikes the perfect balance — strong enough to support serious upgrades, smooth enough to enjoy every mile. It’s the clutch you install when you’re done replacing stock parts and ready for real performance.
What to Expect
Like most high-performance twin disc clutches, some light noise or chatter during initial break-in is normal. Follow McLeod’s recommended break-in procedure and you’ll be rewarded with consistent engagement, long-term durability, and confidence under load.
Bottom Line
The McLeod RST Twin Disc Clutch Kit delivers serious holding power, smooth street drivability, and no-excuses performance. If your build is making power and you still want to enjoy driving it, this is the clutch that keeps up.
