60 Degree Aluminum Bend, 2.75" O.D. - Polished

Matching bends from one supplier make a charge pipe far easier to fabricate, because the diameter, wall and finish line up at every joint. Vibrant 2818 is the 60 degree piece in the company's 2.75 in O.D. polished aluminum family, which also includes a 90 degree bend (2881) and a 120 degree bend in the same size. It is mandrel bent from 6061 aluminum and polished, and Vibrant describes its aluminum tubing as suited to both pressurized and naturally aspirated systems.

Where a 60 degree bend earns its place

A 60 degree change of direction rescues a lot of awkward intercooler routes. Two 60s offset a pipe around a radiator support or frame horn with less restriction than a pair of 90s, and a single 60 often lines a throttle body up with a front-mount core that sits lower than the intake. The 2.75 in size falls between the common 2.5 in and 3 in kit sizes, which makes it useful when a system needs more flow without stepping all the way to 3 in couplers and clamps.

Working with the polished finish

The mirror polish looks finished out of the box, but it scratches easily. Tape the outside before marking and cutting, deburr the cut edges, and clean the weld zone back to bare metal with a stainless brush kept only for aluminum. Bead-roll any end that will take a silicone coupler, because a smooth polished tube can push out of a hose under boost.

Frequently Asked Questions

What are the exact radius and leg lengths?

Vibrant dealer spec sheets differ slightly, listing a centerline radius of 4.125 in or 4.25 in and legs of 5.5 in or 6.0 in. Measure the bend when it arrives before you lay out cuts on a tight route.

Which 2.75 in bends pair with it?

Vibrant makes the same polished 2.75 in O.D. tube as a 90 degree bend (part 2881) and a 120 degree bend, so a full charge pipe can be built from one matched family. Straight 6061 tubing in the same size fills in the long runs.

Does the bend come with couplers or clamps?

No. Part 2818 is a single 60 degree aluminum bend. Pair it with silicone couplers sized for a 2.75 in O.D. tube and a T-bolt clamp on each joint.
