Our selection focuses on the parts that matter most for day-to-day ownership and service work.
Valve Shims & Adjustment Components
Correct valve clearance is critical for power, smoothness, and engine longevity. We carry K&L Supply valve shim kits and individual shims sized for Triumph’s shim-under-bucket systems on liquid-cooled twins and triples, as well as air-cooled models. These hardened-steel shims help restore factory clearances without guesswork.
Oil Filters & Lubrication
Protect the heart of your Triumph with high-quality spin-on and cartridge oil filters, including Maxima ProFilter options with M-Pleat technology for greater contaminant capacity and longer service life. Pair them with the right oil capacity and change interval for your model.
Carburetor & Fuel System Parts
For carbureted Triumphs (and select EFI support items), we stock complete K&L carb repair kits, float needles, float bowl gaskets, drain screws, and petcock rebuild kits for Keihin and Mikuni carbs. Restore smooth throttle response and reliable starting.
Gaskets & Seals
Stop leaks and protect internal components with quality gaskets, including Cometic clutch cover gaskets and other sealing solutions designed to handle heat and pressure.
Ignition & Maintenance Essentials
NGK nickel and iridium spark plugs, cam chain tensioners (including upgraded billet options), oil filler caps, and related service items round out the selection so you can complete common jobs in one stop.

Engine Parts Frequently Asked Questions (FAQs)
What Triumph models do these engine parts fit?
Most parts are designed for modern Triumphs (roughly 1992 onward), including Bonneville, T100/T120, Thruxton, Scrambler, Street Triple, Daytona 675, Tiger, Speed Triple, and Rocket III. Always verify year, model, and engine size on the individual product page or contact us with your VIN for confirmation.
How often should I check valve clearances on my Triumph?
Triumph typically recommends checking valve clearances every 12,000–18,000 miles (or as specified in your service schedule), more frequently under hard use. Many liquid-cooled models use a shim-under-bucket system; having the correct K&L shim kit on hand makes the job straightforward.
Which oil filter should I use?
We carry OEM-style replacements and upgraded options such as Maxima ProFilter spin-on filters. Choose based on your model’s filter type (spin-on or cartridge) and follow Triumph’s oil and filter change intervals (usually every 5,000–6,000 miles or annually).
Do you carry carb rebuild kits for older Hinckley Triumphs?
Yes. K&L carb repair kits, float needles, bowl gaskets, and petcock kits are available for many carbureted models (Keihin and Mikuni). These are ideal when restoring throttle response or fixing leaks on pre-EFI bikes.
Are these parts suitable for both street and higher-mileage bikes?
Yes. The majority of our engine parts are high-quality replacements or mild upgrades that meet or exceed OEM specifications, making them appropriate for daily riders and higher-mileage machines alike.
Can I use these parts with synthetic oil?
Most oil filters and gaskets in this collection are fully compatible with conventional, semi-synthetic, and full-synthetic motorcycle oils that meet Triumph’s API and JASO specifications.
Where can I find the correct service intervals and procedures?
Refer to your model’s official Triumph service manual for torque specs, clearances, and procedures. You can also check Triumph’s owner resources for general maintenance guidance.
