Royal Enfield Silencer Clamp Black (Exhaust Joint Band)

Royal Enfield Silencer Clamp Chrome (Exhaust Joint Band) 

Fix exhaust leaks and rattles at the header-to-silencer joint with the genuine Royal Enfield Silencer Clamp — Part No. 1040747/A. This factory clamp delivers the correct band width, radius and fastener spec for a gas-tight seal on UCE BS4 slip joints—no warped bands or uneven pressure like copy clamps.
Fitment is confirmed across Classic 350 ABS BS4 color/trim variants, Classic 500 BS4 special editions (Pegasus, Redditch, Tribute, Stealth, etc.), and Thunderbird X 500 ABS BS4. Use it whenever the joint has been disturbed, after a silencer swap, or when chasing popping on over-run caused by tiny leaks. Clean the slip joint, seat the can fully, then tighten the OE clamp evenly and re-torque after a heat cycle.
