Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 – Product Overview
The Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 is a performance-focused 5-speed manual transmission package from Bowler Performance Transmissions. It is designed, tested, and built for the aftermarket, giving GM LS builders a package that combines a TKX transmission with important supporting drivetrain components.
This product belongs to the Bowler Performance GM LS TKX 5-Speed Transmission Packages line and is identified by Manufacturer’s Part Number 1517805 and Summit Racing Part Number BTM-1517805.
The package is built around the Tremec TKX transmission platform, which offers 600 lb-ft of torque capacity and supports engine speeds up to 8,000 rpm, with shifts at up to 7,500 rpm. This makes it suitable for performance-focused LS applications when the complete drivetrain is correctly matched.
The transmission uses a 5-speed gear layout with 2.87 first gear, 1.00 fourth gear, and 0.68 fifth gear overdrive. This combination gives buyers strong low-speed engagement with overdrive capability for more relaxed cruising.
The transmission uses a 1.125-inch input shaft diameter with 26 input splines. It also uses a 31-spline output shaft with a 1.360-inch output shaft spline diameter. These details help confirm clutch and yoke compatibility.
Unlike transmission-only listings, the Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 is sold as a kit. The supplied special attention note states that it includes the transmission, bellhousing, clutch, hardware, hydraulic throwout bearing, fluid, pigtails, yoke, and transmission mount.
Fitment and Application Details
The Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 is designed for GM LS RWD applications using a Chevy bellhousing bolt pattern. The supplied application details list the Transmission Manufacturer Code as Tremec TKX, Drivetrain as RWD, and Bellhousing Bolt Pattern as Chevy.
This package is intended for aftermarket GM LS manual transmission conversions where a TKX 5-speed transmission and supporting components are required.
Fitment should be confirmed before ordering by checking the engine, bellhousing pattern, clutch requirements, flywheel compatibility, pilot bearing, hydraulic clutch setup, transmission mount location, crossmember position, driveshaft length, tunnel clearance, shifter mounting pattern, yoke requirements, reverse light wiring, electronic speedometer setup, and overall drivetrain layout.
The package includes a cast aluminum bellhousing, RAM single disc clutch kit, billet steel flywheel, Tilton 6000 Series hydraulic throwout bearing, roller pilot bearing, slip-on yoke, and other supporting components. These included parts make the package more complete than a standalone transmission.
The shifter is not included. The supplied notes state that the package requires a shifter with 0.890-inch center-to-center 3/8-inch diameter mounting holes. Buyers should confirm the correct shifter before installation.
The TKX platform is designed for multiple applications with three shifter locations and a compact, end-loaded design that provides clearance in most transmission tunnels without floor modifications in many applications.
Build Quality and Reliability
The Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 is built around the Tremec TKX, a modern 5-speed manual transmission platform designed for strength, compact fitment, and performance drivability.
The TKX offers 600 lb-ft torque capacity, which gives the transmission strong power-handling ability when the complete drivetrain is properly matched. It is also capable of engine speeds up to 8,000 rpm, with shifts at up to 7,500 rpm.
The transmission case is made from aluminum, supporting a strong yet manageable transmission housing. Aluminum case construction is commonly valued in performance drivetrain applications because it provides strength without unnecessary weight.
The included RAM single disc clutch kit uses spring hub discs and includes a billet steel flywheel with required hardware. The supplied product details state that this clutch package is good for up to 550 hp.
The package also includes a Tilton 6000 Series throwout bearing with -4AN inlet and remote bleeder, supporting a modern hydraulic clutch setup.
The included Energy Suspension transmission mount helps complete the drivetrain installation package, while the Royal Purple Synchromax fluid supports the transmission’s fluid requirement from the start.
This package also includes reverse light and electronic speedometer pigtail connectors, giving installers important wiring components for a more complete setup.
What Makes This Transmission Package a Strong Choice
The Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 is a strong choice for buyers who want more than a standalone transmission. It includes many of the major parts needed to plan a GM LS TKX manual transmission conversion.
One of its strongest advantages is the complete package format. The kit includes the GM TKX 5-speed transmission, cast aluminum bellhousing, clutch kit, billet steel flywheel, hydraulic throwout bearing, roller pilot bearing, fluid, pigtails, yoke, and transmission mount.
The 600 lb-ft torque capacity gives the TKX platform serious performance capability, while the 0.68 fifth gear overdrive helps reduce engine rpm during cruising when the drivetrain is properly matched.
The 2.87 first gear supports strong low-speed engagement, while the 1.00 fourth gear provides direct-drive operation.
The included Chevy bellhousing and GM LS-focused package layout make this kit especially useful for buyers working on compatible LS swap or LS retrofit projects.
The package also provides practical installation support through the included reverse light pigtail, electronic speedometer pigtail, transmission mount, hydraulic throwout bearing, and fluid.
For builders who want a strong 5-speed manual transmission package with Bowler Performance preparation and Tremec TKX capability, the 1517805 offers a focused GM LS drivetrain solution.
Ideal Buyers and Use Cases
The Bowler Performance GM LS TKX 5-Speed Transmission Packages 1517805 is best for LS swap builders, GM performance vehicle owners, custom drivetrain installers, restoration shops, hot rod builders, and professional mechanics working on compatible RWD GM LS applications.
It is suitable for buyers who need a Tremec TKX 5-speed transmission package with a Chevy bellhousing bolt pattern, 26-spline input, 31-spline output, slip-on yoke, and 0.68 overdrive.
This product is also useful for buyers who want a kit that already includes major supporting components such as the bellhousing, clutch kit, flywheel, hydraulic throwout bearing, yoke, pigtails, fluid, pilot bearing, and transmission mount.
It is not a fully universal installation kit. The shifter is not included, and the package requires a shifter with 0.890-inch center-to-center 3/8-inch diameter mounting holes.
The best buyer for this product is someone who has already confirmed LS engine compatibility, vehicle tunnel clearance, shifter position, crossmember setup, driveshaft length, hydraulic clutch routing, electronic speedometer needs, and complete installation requirements.
