Description

Richmond Gear Internal Rail 5-Speed Transmissions R502064C – Product Overview

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C is a performance-focused 5-speed manual transmission from Richmond Gear. It belongs to the Richmond Gear Internal Rail 5-Speed Transmissions product line and is supplied as a new, non-remanufactured transmission assembly sold individually.

This product is identified by Manufacturer’s Part Number R502064C, Summit Racing Part Number RMG-R502064C, and UPC 698231347508. These identifiers help buyers, mechanics, and parts departments confirm the correct transmission before ordering.

The transmission uses a 1.125-inch input shaft diameter with 26 input splines. It also uses a 31-spline output shaft with a 1.389-inch output shaft spline diameter. These specifications are important for selecting the correct clutch disc and output yoke.

This model has a 5-speed gear layout with a 2.87 first gear, 1.00 fourth gear, and 0.64 fifth gear. The fifth gear provides overdrive capability for buyers who want performance manual control with improved cruising behavior.

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C has an aluminum case and a slip-on yoke style. The yoke is not included, so buyers should select the correct compatible yoke separately.

This transmission does not include a bellhousing, does not include a yoke, and does not include a shifter. It requires a Long-style shifter, and the supplied notes list the shifter location as center position.

Fitment and Application Details

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C is intended for compatible performance applications requiring a 5-speed manual transmission with a center-position shifter layout.

Fitment should be confirmed before purchase by checking the original transmission configuration, bellhousing pattern, clutch disc spline count, pilot bearing, flywheel, clutch release setup, output yoke, driveshaft length, transmission mount, crossmember position, tunnel clearance, and shifter location.

Because the input shaft uses 26 splines, this transmission requires a compatible 26-spline clutch disc. Because the output shaft uses 31 splines, the yoke must be selected to match the correct output shaft configuration.

The slip-on yoke style is an important driveline detail. Since the yoke is not included, buyers should confirm the correct yoke before installation.

The transmission requires a Long-style shifter, but the shifter is not included. The supplied note states center position shifter location, so buyers should verify that this location works with the intended interior layout, console position, and transmission tunnel.

The bellhousing is not included, so buyers should confirm engine compatibility and select the correct bellhousing before ordering.

For buyers browsing the manual transmissions category, this product fits naturally with related drivetrain parts such as clutch kits, flywheels, pilot bearings, bellhousings, Long-style shifters, slip-on yokes, driveshaft parts, transmission mounts, and installation hardware.

Build Quality and Reliability

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C is built with aluminum case material, giving the transmission a strong and practical housing for performance use.

Richmond Gear describes its Internal Rail 5-speed transmissions as being packed with power and speed. The product line is built around ongoing research and development, along with extensive testing at Richmond’s facilities.

This focus on development and testing gives buyers confidence that the transmission is designed for serious manual drivetrain performance.

The internal rail design is part of the product line identity and supports a focused 5-speed manual transmission layout. Buyers who require this Richmond Gear transmission configuration should confirm fitment details carefully before ordering.

The gear ratio spread includes 2.87 first, 1.89 second, 1.28 third, 1.00 fourth, and 0.64 fifth. This provides performance-focused lower gears with an overdrive fifth gear for improved cruising.

The transmission is listed as not remanufactured, meaning it is not supplied as a rebuilt used unit.

What Makes This Transmission a Strong Choice

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C is a strong choice for buyers who need a 5-speed manual transmission with clear performance specifications and overdrive drivability.

One of its strongest features is the 0.64 fifth gear. This overdrive ratio can help reduce engine rpm during cruising when matched with the correct rear axle ratio, tire size, and vehicle setup.

Another important feature is the 2.87 first gear ratio, which supports strong low-speed acceleration in compatible applications.

The 26-spline input shaft and 31-spline output shaft give installers clear requirements for clutch disc and yoke selection. This helps reduce confusion during drivetrain planning.

The center position shifter location is another key detail. Shifter location matters in performance builds because it affects driver reach, console alignment, tunnel clearance, and overall driving comfort.

The aluminum case adds value by supporting strength while keeping unnecessary weight lower than heavier case materials.

For buyers who want a Richmond Gear 5-speed manual transmission with overdrive, internal rail construction, and clearly supplied drivetrain specifications, the R502064C offers a focused transmission solution.

Ideal Buyers and Use Cases

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C is best for vehicle owners, performance builders, mechanics, drivetrain installers, and restoration shops working on compatible manual transmission applications.

It is suitable for buyers who need a 5-speed manual transmission with a 2.87 first gear, 0.64 fifth gear overdrive, 26-spline input shaft, and 31-spline output shaft.

This product is also useful for builds requiring a center position shifter location and a Long-style shifter.

It is not a complete installation kit. The bellhousing is not included, the yoke is not included, and the shifter is not included. Buyers should confirm all supporting drivetrain parts before ordering.

The best buyer for this product is someone who has already confirmed bellhousing fitment, clutch disc spline count, yoke requirements, shifter style, center shifter placement, driveshaft length, and vehicle installation needs.

Technical Specifications

Ordering Support and Fitment Guidance

Before ordering the Richmond Gear Internal Rail 5-Speed Transmissions R502064C, buyers should confirm the full drivetrain setup for the intended application.

Important details include bellhousing compatibility, clutch disc spline count, flywheel, pilot bearing, clutch release system, output yoke, driveshaft length, transmission mount, crossmember position, tunnel clearance, shifter style, and shifter location.

This transmission uses a 26-spline input shaft, so the clutch disc must match that spline count. It also uses a 31-spline output shaft with a slip-on yoke style, so the yoke must be selected correctly.

The bellhousing is not included, yoke is not included, and shifter is not included. A Long-style shifter is required.

The supplied note lists a center position shifter location, so buyers should verify that this placement works with the vehicle’s interior and tunnel layout.

For a complete drivetrain installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, bellhousing, slip-on yoke, driveshaft parts, Long-style shifter, transmission mount, fluid, and installation hardware.

The Richmond Gear Internal Rail 5-Speed Transmissions R502064C is built for buyers who want a Richmond Gear manual transmission with performance gearing, overdrive capability, aluminum case construction, and clear fitment specifications.
