Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Transmission Complete Gear Sets
- Compatibility: Ensure gear sets match your Harley's model (e.g., Big Twin with Cruise Drive 6-speed, 4-speed or 5-speed transmissions) and year (e.g., 1946-1984 FL/FLH, 1986-2006 Softail). Use the vehicle selector for precise fits, including engine sizes like 96 ci, 103 ci, 110 ci to avoid shifting or power transfer issues.
- Type of Use: For easier parking or reverse functionality, opt for mechanical reverse kits; performance tuning or overdrive benefits from 6/7-speed gear sets for smoother shifting and optimized torque/power in street or touring conditions.
- Components and Upgrades: Select complete sets with gears, shafts, trap doors, bearings, detent components, gaskets, and hardware; upgrade to reverse kits with electronic cut-off switches for added safety and no exhaust modifications.
- Brand and Quality: Choose BAKER DRIVETRAIN for dyno-tested 6/7-speed sets with roller detent drums, ANDREWS for high-nickel alloy steel gears (heat-treated/shot-peened), or MOTOR TRIKE for lightweight aluminum reverse kits. Prioritize USA-made quality for durability and performance.
- Installation and Cost: Sets are direct replacements or case fits with included components; reverse kits install without exhaust changes. Prices range from $1,018.95 for 4-speed sets to $3,695 for 7-speed—factor in made-in-USA quality and free shipping over $99 for value.
Frequently Asked Questions (FAQs)
- What Harley models do these transmission complete gear sets support? Sets support Big Twins with Cruise Drive, 4/5/6/7-speed transmissions, and models like FL/FLH (1946-1984), Softail (1986-2006)—use the year/make/model filter for exact compatibility.
- How do overdrive gear sets improve performance? They lower RPM at cruising speeds with optimized ratios (e.g., 3.76:1 first, 1.00:1 seventh) for better torque/power on 96/103/110 ci motors.
- What is typically included in a gear set? Sets include gears, mainshaft, countershaft, trap doors, bearings, snap rings, gaskets, hardware; reverse kits add electronic switches and aluminum housings.
- Are reverse kits suitable for all exhausts? Yes, designed with no modifications needed for OEM exhaust, making them ideal for parking assistance on heavy bikes.
- What if a set doesn't fit my Harley? Verify transmission type (4/5/6-speed), engine size, and model before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related drivetrain parts? Yes—explore clutches, belts, sprockets, or full drivetrain kits in the Harley drivetrain category to complement your gear set upgrade.
