50-State Legal (CARB EO D-553-30)
SEMA Cert. SC-BDD01-0138
Thicker Casting • Anti-Warp

Why This Kit Works

Factory HEMI manifolds are prone to bolt failures, leaks, and warping. These upgraded manifolds use a thicker, uniform-wall casting and longer bolts with spacers to manage thermal expansion. The heat shield mounts independently—reducing stress on fasteners—while machined mating surfaces ensure a secure, long-term seal.

  • High-silicon ductile iron resists cracking and heat fatigue
  • Uniform wall thickness combats distortion and warping
  • Independent heat-shield mounting reduces bolt stress
  • Precision-machined flanges for reliable sealing

About This Product

Engineered specifically for Dodge/Ram 5.7L HEMI trucks, these manifolds address the root causes of leak-prone OE units. Thicker, stress-relieved castings and revised hardware geometry keep the sealing surfaces flat and fasteners happy—even after repeated heat cycles—so your truck stays quiet, efficient, and ready to tow.

Vehicle Fitment & Important Notes

  • Fits: Ram 1500 DS (2009–2024), 2500 DJ (2009–2018), 3500 D2 (2013–2018), 3500 DC (2011–2015)
  • Does NOT fit 2019+ DT body style — use 1041467 (search our site for PN).
  • VIN quick check: 6th digit “6” or “7” = 1500 Classic (DS) → these manifolds fit.
  • OE interchange: Left 68045559BA/AB, 53034137AC, 68045559AA/AB • Right 5045486AA, 68045560AB, 53034138AC, 68045560AA
  • Replaces OEM: Left 68591573AB, 68591585AA • Right 68591572AB, 68591586AA
Emissions: Covered under CARB EO; legal for sale and use in all 50 states.
SEMA Certification: SC-BDD01-0138 • CARB EO: D-553-30

Frequently Asked Questions

  • Are these manifolds 50-state legal?

    Yes. They’re covered by CARB EO D-553-30 and are legal for sale and use in all 50 states.

  • How do I know if my Ram 1500 is DS or DT?

    Check your VIN: if the 6th digit is a 6 or 7, it’s a 1500 Classic (DS) and this kit fits. DT (2019+) requires PN 1041467.

  • What problems do these manifolds solve?

    They address common issues like broken bolts, warping, and exhaust leaks by using thicker ductile iron castings, longer bolts with spacers, and independent heat-shield mounting.

  • What’s included in the kit?

    New manifolds, bolts, nuts, spacers, and gaskets—everything needed for a clean install.

  • Can I buy just one side?

    Yes. Left (Driver) is PN 1041465; Right (Passenger) is PN 1041464. The kit on this page is the DS/DJ/D2/DC fitment.

  • How long is installation?

    Plan about 2 hours 18 minutes with standard tools.

  • What’s the warranty?

    36-month / 75,000-mile parts warranty. Keep your proof of purchase and follow install best practices.
