Gauge Accessories

Gauge Accessories: the small parts that make a gauge read right

Gauge accessories are the adapters, interface modules, replacement gauges and faceplate hardware that get an instrument reading correctly and looking right in the dash or on the bars. A tach adapter takes a signal a factory system does not hand off cleanly and turns it into something a tachometer can count. A GPS speedometer interface pulls vehicle speed from satellite data when there is no usable sender to tap. A replacement speedo swaps a dead or wrong-face unit. And faceplate and anti-glare kits keep a tuner display readable and protected. If you have ever chased a jumpy tach on a distributorless engine or fought a speedo with no signal, this is the box those problems get solved in.

What ThreePiece stocks

This category holds 16 products from 3 brands: AutoMeter (7 in the sample), Bikers Choice (6) and COBB (3). Prices currently run from $29 to $331 for what is in stock, which is a snapshot of live inventory rather than a fixed promise. At the top end sits the AutoMeter Universal GPS Speedometer Interface Module 5289, with the AutoMeter Tach Adapter for Distributorless Ignitions 9117 filling the signal-conditioning role. Bikers Choice covers Harley hardware with parts like the L84-90XL replacement speedo with black face and the Big Twin & XL 8000 RPM electronic mini tachometer. At the low end, COBB parts like the Accessport V3 black faceplate and the Accessport V3 anti-glare film and cleaning kit handle tuner display cosmetics and protection.

How to choose

Start with the job. If a gauge reads wrong or not at all, you want a signal fix - a tach adapter or a GPS interface, not a new gauge. If the gauge itself is dead or wrong-faced, a replacement speedo or tach is the call. If your display works fine and you just want it cleaner or protected, the COBB faceplate and anti-glare parts are the cheap end of the range. The spread here is real: the sub-$45 COBB items are cosmetic and protective, while the AutoMeter modules over $150 are doing electrical work. Match the part to the fault, not to the price tag.

What else you need with it

Gauge work rarely happens alone. If you are wiring a signal adapter, the Electrical Accessories category covers the connectors and hardware around it. Bar-mounted riders reworking a cockpit will also want Handlebars, Grips and Quick Release Levers. Browse the full Interior section for the rest, or check Audio Systems if the dash rebuild is going further.

Fitment and ordering

Fitment data here is limited - only 2 of these products carry it, and it points to Harley-Davidson XL, FX, FXR and FXRS models across roughly 1983 to 2013. Most items are universal or application-specific by part number, so confirm before you buy. Use our fitment calculator for wheel work, or call fitment help at 813-535-5801 to check a gauge accessory against your vehicle. Every order ships free, and Affirm and Katapult financing is available. Questions on a part number? Reach us through contact us.
