Steering Universal Joint (U-joint)
This heavy-duty steering universal joint is precision-engineered for custom steering systems, classic truck builds, hot rod applications, and LS swap projects. Available in Black or Silver finish, it covers a wide range of shaft combinations — from smooth bore to DD (Double-D) and splined configurations — so you can find the exact match your build requires.
Each joint is offered in two color/finish options and spans four connection categories:
- Smooth Bore: 3/4" and 1" smooth bore on either or both sides — ideal for slip-fit column and shaft connections.
- Spline × Spline: Combinations of 3/4"-30, 3/4"-36, 11/16"-36, and 13/16"-36 spline shafts on both sides — perfect for direct spline-to-spline steering column connections.
- DD × DD / DD × Smooth Bore / DD × Spline: Double-D shaft on one or both sides, compatible with 3/4" DD and 1" DD configurations — the go-to choice for GM columns, rack-and-pinion conversions, and aftermarket steering shafts.
Key Features:
- Heavy-duty steel construction — engineered for strength and long-lasting durability under real driving conditions
- Multiple shaft interface options: Smooth Bore, Double-D (DD), and Spline (30T & 36T) on both Side A and Side B
- Available in Black (powder coated) and Silver (polished/nickel) finish
- Reduces slop and play in the steering linkage for tighter, more responsive steering feel
- Compact design fits tight engine bay and firewall clearances common in C10 trucks, muscle cars, and swap builds
