    Why Buy from CPP Diesel

    • 2nd-Gen Focus: Parts sized for 24-valve packaging—radiator support, battery tray, and A/C clearance.
    • Pro Materials: 6061 aluminum & 304 stainless in common 2.5"–4.0" sizes for intercooler/exhaust builds.
    • Everything in One Cart: Bends, bungs, V-bands, brackets, and bead-rolling tools.
    • Fast Shipping: Popular bends, clamps, and kits ship quickly from U.S. warehouses.

    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.
    • V-bands: Match the flange profile and diameter to your turbo outlet (e.g., HX40 uses 3905216-style 4" clamp).
    • 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.
