Model-specific aftermarket replacements
Biker Bling selects these replacements for the listed original fixing positions. The Triumph references identify the original components replaced, not Biker Bling product codes. These are aftermarket replacement parts, not genuine Triumph-branded components.
Materials and appearance: The supplied nuts are stainless steel. Their appearance may differ from the originals. Material alone does not establish equivalent mechanical strength.
When should you replace these fixings?
- Corroded or damaged nuts: Inspect the nuts and stud threads before exhaust removal.
- Worn tool flats: Damaged nuts can make future exhaust servicing difficult.
- Header servicing: Check the studs, flanges and sealing arrangement before reassembly.
New nuts cannot repair damaged studs, distorted flanges, leaking exhaust gaskets or cracked exhaust components.
Fitting information
Work on a cold exhaust and follow Triumph’s procedure for header support, gasket condition, flange alignment, fastener specification and tightening sequence. Start nuts by hand and use the specified torque and thread condition. Do not force a binding nut or use extra tightening to compensate for an exhaust leak. Use anti-seize only where appropriate under the specified procedure. Check the assembly is secure and inspect for leaks after fitting.
For general guidance, read our guide to threadlocker and anti-seize on motorcycle bolts. Triumph’s workshop procedure takes precedence.
Customer questions
