V-Twin Throttle Sleeve — Dual Nylon Throttle Tube for 1" (25.4 mm) Bars, Harley Fit

This durable replacement throttle sleeve from V-Twin is made of molded nylon and built for compatibility with a range of Harley-style models. It replaces worn or damaged inner throttle tubes to restore the proper rotational feel and secure grip fit for dual-throttle setups. The 35-9870 is paced for riders who want a direct swap that works with standard 1" handlebars and common throttle housing geometries.

Which motorcycles will this throttle sleeve fit?

The throttle sleeve is specified for many V-Twin-compatible Harley models from the mid-1990s onward. It fits the most common 1" bar applications used on these bikes and matches factory-style dual-throttle assemblies. Always verify part compatibility with your bike's year and handlebar configuration before ordering.

• FXST models 1996 and up
• FLST models 1996 and up
• FXD models 1996 and up
• XL models 1996 and up
• FLT models 1996–2007

How does a dual-type nylon throttle tube perform compared to alternatives?

Nylon throttle sleeves offer a good balance of strength, wear resistance, and low friction for cable-actuated throttles. The dual-type design accepts two grip halves and maintains alignment under load, delivering predictable throttle response without binding when installed correctly.

• Molded nylon resists abrasion and handles heat and humidity well
• Dual-type profile keeps both grip halves aligned for smooth rotation
• Low-friction surface helps reduce throttle stiffness over time
• Lightweight construction minimizes added handlebar mass

What should I check before installing the 35-9870 throttle sleeve?

Inspect your handlebar inner diameter, throttle housing clearance, and cable routing to ensure the sleeve will seat correctly. Look for worn bearings or housing cracks and replace any damaged components to prevent premature wear on the new sleeve.

• Confirm handlebars are standard 1" (25.4 mm) inside diameter
• Verify throttle housing is compatible with dual-type tubes
• Check throttle cables for fray or slack and replace if necessary
• Clean mounting surfaces and lubricate lightly if recommended

How easy is installation and what tools are typically needed?

Installation is straightforward for most mechanically minded riders and can often be completed with basic hand tools. You may need a flat screwdriver, Allen keys or socket set for housing removal, and a cloth to clean mating surfaces before assembly.

• Remove grips and throttle housing to access the old tube
• Slide out the worn sleeve and compare new part for orientation
• Reinstall throttle tube, grips, and housing, then verify free play
• Adjust cable tension to factory specifications after assembly

Who this is for: Riders maintaining or restoring late-model Harley-style cruisers who need a reliable, OEM-compatible replacement throttle tube. The V-Twin 35-9870 suits mechanics, custom builders, and DIY enthusiasts who require a durable nylon dual-type sleeve for 1" handlebars on FXST, FLST, FXD, XL (1996+), and FLT (1996–2007) models. Choose this part when you want a direct-fit, long-wearing option to regain smooth throttle rotation without modifying your bars or housings.
