Helpful Notes

• Tubing size: Most 98.5–02 intercooler piping uses 3.0" OD; big-power setups may step to 3.5".
• Material choice: 304SS for heat/corrosion and welding; aluminum for light weight and easy bead-rolling.

• Weld bungs: Add -AN bungs for clean plumbing of returns, vents, and sensor ports.
• Traction bars: Weld-on brackets reinforce the axle/spring perch and curb wheel hop on tuned/towing rigs.

Frequently Asked Questions

What size tubing should I use for custom intercooler pipes?

Most 24-valve builds are 3.0" OD. Use quality bends from the Fabrication Components catalog for clean routing.

Which V-band fits my HX40 outlet?

The 4" HX40 turbine outlet uses a clamp like Cummins 3905216 (or the CPP equivalent).

Can I bead-roll aluminum and stainless?

Yes—our CPP 2990 bead roller works on common aluminum and thin-wall stainless to keep couplers from blowing off.

Do the traction bar brackets fit a 2nd-Gen Ram?

They’re universal weld-on—match to your axle tube diameter and bar design. See the rear brackets and front mounts.

Is there a direct-fit option if I don’t want to fab my own pipes?

Yes—choose our stainless 98.5–02 kit or the polished version.
