Precision Shaft Technologies Drive Shaft Slip Yoke
PST Drive Shaft Slip Yokes: Performance-Built for Street and Race
When it comes to driveline integrity, few components are as critical — or as frequently overlooked — as the drive shaft slip yoke. It connects your transmission's output shaft to the driveshaft, allowing for the axial movement that naturally occurs as your suspension cycles through its travel. A poorly made slip yoke introduces slop, vibration, and wear into an otherwise solid driveline. That's why serious builders turn to Precision Shaft Technologies (PST) when it's time to specify this component correctly.
A Manufacturer Rooted in Driveline Expertise
Founded in 2002 and based in Clearwater, Florida, Precision Shaft Technologies has built its reputation as a leader in performance driveshaft manufacturing. The company's expertise spans the full driveline system — from complete custom shafts to the individual components that tie everything together. That holistic, system-level knowledge is exactly what informs the design of their slip yokes: these aren't generic catalog parts, but components engineered to work in harmony with high-performance driveshafts under real-world stress.
Slip Yoke Specifications That Match Your Build
PST's slip yoke lineup covers a wide range of popular GM and performance transmission applications. Their steel yokes are offered in both 27-spline and 32-spline configurations, accommodating transmissions such as the TH350, TH400, 4L80E, 4L85E, Muncie, Powerglide, Super T10, T56, Borg Warner T5, and Richmond units. U-joint series compatibility spans the common 1310 and 1350 series, allowing builders to properly match their yoke to their torque requirements — a detail PST's own technical documentation emphasizes as essential for long-term durability.
For example, PST's 1310-series steel slip yoke for 32-spline T400/4L80 applications features a 5.5" length to the center of the U-joint, a 1.885" barrel diameter, and a 4" barrel length — dimensions engineered for proper engagement and smooth sliding action under load. Their 27-spline version for Borg Warner and GM applications uses the same 1310 joint series but with a 1.5" barrel diameter optimized for lighter-case transmissions like the T350 and T-56. PST also offers a dedicated dirt track racing slip yoke for use with Brinn, Bert, Falcon (Winters), Muncie, and Powerglide transmissions — a nod to their deep roots in circle track and drag racing applications.
Why PST Slip Yokes Stand Out
- Steel construction: All slip yokes are manufactured from steel for strength and wear resistance, unlike some budget alternatives that use softer alloys.
- Broad transmission compatibility: Coverage spans the most popular domestic performance and race transmissions, from the venerable TH400 to modern electronically controlled units like the 4L80E.
- Proper U-joint series matching: PST's lineup is organized by U-joint series (1310, 1350) so builders can correctly match the yoke to the torque capacity of the rest of the driveline.
- Race-proven pedigree: PST's components are trusted by championship-level drag racers and circle track competitors — the same engineering discipline carries through to every slip yoke they produce.
Whether you're performing an LS swap, building a dedicated drag car, or refreshing the driveline on a high-power street machine, PST's slip yokes deliver the fit, finish, and strength that demanding applications require.
