Diamond Eye 3-1/2in Band Clamp with Metric Hardware Aluminized Steel for 1998.5-2018 Dodge Ram Cummins 3.5" Exhaust
The Diamond Eye BC350A band clamp secures 3.5" outer diameter exhaust pipes on Dodge Ram 2500 and 3500 Cummins diesel trucks along with SUVs and performance vehicles. It creates a tight seal that resists vibration and high heat for consistent exhaust flow in demanding conditions. Built for custom exhaust fabrication and reliable replacements this clamp handles road abuse with precision fit.

Clamps
Exhaust clamps, hose clamps, and line clamps are the small hardware that keeps performance systems sealed and rattle-free. Whether you are finishing an exhaust build, routing coolant lines, or securing boost piping on a turbocharged engine, the right clamp makes the difference between a clean install and a leak.Popular UpgradesBand clamps and slip-fit exhaust clamps are the most popular choice for performance exhaust work, providing a tight seal without crushing the pipe. T-bolt clamps are preferred for silicone couplers on intercooler and intake piping where high boost pressure demands extra clamping force. Stainless steel construction is standard on quality performance clamps for corrosion resistance under heat cycling.What clamps work best for exhaust connections?Lap-joint exhaust clamps and two-bolt band clamps are the most common choices for slip-fit exhaust connections. For a cleaner look with leak-free performance, v-band clamps paired with matching flanges offer the best res...

Diamond Eye Performance
Diamond Eye Performance manufactures mandrel-bent exhaust systems and components for diesel trucks, with a catalog that spans DPF-back, turbo-back, and cat-back exhaust for Cummins, Duramax, and Power Stroke platforms. CNC mandrel bending maintains full internal tube diameter through bends from 3/8-inch to 5-inch OD in both aluminized and stainless steel, ensuring exhaust gas flow is not restricted by collapsed bends common in lesser exhaust systems.Popular UpgradesDiamond Eye 4-inch DPF-back exhaust systems for the Cummins 6.7L and Duramax 6.6L diesel trucks are the most popular products, providing a meaningful reduction in exhaust restriction over the factory 3.5-inch outlet section. Stainless steel mandrel-bent kits are available for the Ram 2500, Ram 3500, Ford Super Duty, and GM HD truck platforms with direct-fit connections and tip options. Aluminized exhaust kits offer the same mandrel-bent quality at a lower price point for builds in drier climates where corrosion is less of...

Start with tubing (304 or 321 stainless, titanium, or aluminum) in the right diameter and wall thickness, then add mandrel bends, flanges, V-bands, and clamps to complete the joint work. AN plumbing follows the same pattern: match dash size to horsepower target, pair the right hose (PTFE or CPE) with matching hose ends, and use adapters, bulkheads, and distribution blocks to route fuel, oil, and coolant cleanly. Shop by material (stainless, titanium, aluminum), fitting type (AN, ORB, NPT), diameter, or brand (Vibrant, Ticon, Stainless Bros, Radium, Fragola, DEI, ATP). ...
