The SPOOLOGIC Pro-Series V-Band Clamp Kit SL-330-055 bundles 1× Cast Iron Elbow to Downpipe clamp and 1× Turbo to Cast Iron Elbow clamp for a complete 2003-2004 Dodge Ram 2500 3500 5.9L Cummins; Fits 2004 Model Trucks Built Before 12/31/04 V-band joint replacement. Engineered to last a lifetime — stainless from band to latch on every clamp, with no stamped or carbon-steel failure points.

Every clamp in this kit is built from corrosion-resistant 304 stainless steel: a mandrel-formed 304SS band, floating V-segments, a heavy-gauge 304 stainless T-bolt, a flanged stainless lock nut, and a Pro-Series Stainless T-Bolt Latch with Quick-Release Action. The upgraded latch is the critical difference — OEM and budget aftermarket clamps use a thin-gauge stamped sheet-metal latch loop that tears under thermal cycling and clamp tension. That stamped loop is the #1 failure point on factory V-band clamps. The Pro-Series latch eliminates it on every clamp in the kit.

Common V-Band Clamp Failure Symptoms

If your 5.9L 24v Cummins truck is showing any of these symptoms, the factory or budget aftermarket clamps are most likely the cause:

• Latch loop tearing or stretching — the thin-gauge stamped sheet-metal loop on factory and budget clamps tears, lets the T-bolt slip, and the clamp loses tension
• Exhaust or boost leak at the V-band joint — ticking, hissing, or sooting around the clamp under load
• Clamp band stretching or warping from heat cycling — thin OEM bands lose clamping force over time
• Corroded T-bolt or seized nut — non-stainless OEM hardware rusts in place and breaks during service

Complete V-Band Service in One Box

Every joint replaced at the same time means no mixed-old-and-new tension across the exhaust system. Each clamp is application-specific to its joint — no guesswork, no universal-fit compromises. Pro-Series build quality on every clamp, all backed by the same Lifetime SPOOLOGIC Warranty.
