HD Clamps

The HD Clamp system is a leak-proof, quick-release alternative to silicone couplers on intercooler, intake and turbo piping. This collection covers the Vibrant Performance HD clamp assemblies with weld ferrules and O-rings, the newer pinless HD clamps, and titanium and anodized versions.

How the HD clamp works

Two ferrules are welded to the ends of the tubes. O-rings sit in grooves on the ferrules, and a hinged clamp pulls them together. The O-rings seal the joint, and the clamp locks it mechanically so it cannot blow apart under boost.

Pinless HD clamps

The pinless design uses an integrated latch in place of a removable pin, so there are no loose parts to drop and the clamp opens and closes faster.

Sizes and materials

Clamps are sized to tubing outside diameter. Aluminum ferrules weld to aluminum charge pipes, stainless ferrules to stainless, and titanium options suit titanium systems.

Common questions

Why use HD clamps instead of silicone couplers? They do not blow off, they do not swell under boost and they look clean. They are popular on high boost race cars.

Do HD clamps allow any movement? They allow a small amount of misalignment and movement through the O-rings, but long runs between an engine and a chassis-mounted intercooler may still need a flexible section.

Can I buy replacement O-rings? Yes. Replacement O-rings are available and should be changed whenever they look flattened or cracked.

How to Choose

Match the inlet and outlet size to your exhaust tubing, then think about sound and space. Mufflers control overall volume, resonators knock down drone and rasp, flex sections absorb engine movement, and a good clamp or hanger keeps everything sealed and supported.

More Questions

What causes exhaust drone?

Drone usually shows up at highway cruising speed when the exhaust frequency matches the cabin. A resonator placed in the right spot is the most common fix.

Do I need a flex section?

On engines that move a lot on their mounts, especially turbo setups, a flex section near the engine helps prevent cracked welds and broken hangers.
