KustomTech Spinner oil filler cap with dipstick: stay in control in style
Checking the oil level is fundamental to motorcycle maintenance. But who says checking your oil has to be ugly? With this polished brass Spinner KustomTech cap and stainless steel dipstick, you combine practicality and aesthetics at the highest level. Every time you check it, it's a little moment of added visual pleasure.
Brass and stainless steel: the winning duo
The cap body is machined from solid billet brass with KustomTech's signature mirror-polished finish. The dipstick, on the other hand, is made of stainless steel, resistant to corrosion and the heat of engine oil. This combination of premium materials guarantees exceptional durability and a timeless look.
Compatible with Harley 2000 and later
This cap is specifically designed for Harley-Davidson side-fill oil tanks on 2000 and later models. The threads and dimensions are perfectly calibrated for a direct fit without modification. It installs in seconds and instantly transforms the look of your engine area.
The recognizable Spinner style
The Spinner profile with its distinctive fins isn't just about style. It also offers an excellent grip for screwing and unscrewing the cap, even with greasy hands after a day of tinkering. Pair it with the Spinner fuel caps from the same range for a perfectly coordinated look on your Harley.

FAQ — Fuel and oil caps
Is it waterproof?
Yes. High-density nitrile rubber O-ring + precision machined threads = not a leak. E10 fuel and 4-stroke engine oil resistance tested.
Is the thread compatible?
Standard Harley Davidson thread (left-hand thread for the fuel cap on most models). Check the exact model on the product page before ordering.
Difference between screw-on and weld-on?
The screw-on cap = 30-second installation, plug-and-play. The weld-on cap = total customization, requires welding on a custom tank (chopper bobber).

This little oil cap transforms the look of my 2008 Softail. The polished brass contrasts beautifully with the black frame. The stainless steel dipstick is handy for quickly checking the oil level. A must-have for modern Harleys.

Good product, beautiful polished brass. The threading fits my 2003 Fat Boy perfectly. The dipstick is a real plus for checking the oil level without getting your fingers dirty.

Erstklassige Qualität, passt perfekt auf meinen Heritage 2004. Das polierte Messing sieht fantastisch aus neben dem verchromten Motor. Sehr empfehlenswert!
