SKU 2016

Category: Volkswagen IRS High-Performance Axles

A specialized, long-reach axle solution for high-performance Volkswagen IRS (Independent Rear Suspension) vehicles. At 16 1/4" in length, SKU 2016 is designed for custom "wide-track" setups or off-road applications where increased suspension travel requires a longer shaft than the standard factory length. Like the shorter versions in this series, it features a "floating" spline design to eliminate the mechanical binding that frequently destroys CV joints in modified Volkswagens.

Performance & Fitment

  • Application: Long-Travel / Wide-Track IRS Rear Axle Set
  • Length: 16 1/4"
  • Spline: 33-Tooth (1.062" OD, 2 3/8" spline length)

    • VW Type 1 (Beetle/Bug): Ideal for "Baja Bug" builds or long-travel sand rails.

    • VW Type 2 (Bus/Transporter): Heavy-duty replacement for customized IRS rear ends.

    • VW Type 3: Fits IRS-equipped models requiring extended axle length.

    • Compatibility: Designed for standard 33-spline CV joints (Type 1, 924/944, or 002/Bus styles).

    • Premium Construction

    • Material: Forged from high-strength solid alloy steel, engineered to withstand the high-torque demands of performance air-cooled or water-cooled conversion engines.

    • Extended Spline Design: By removing the inboard shoulder, the CV joint is allowed to "float" along the 2 3/8" spline. This accommodates the natural change in axle distance as the trailing arm moves through its vertical arc, preventing the CV cage from bottoming out and shattering.

    • Heat Treatment: Through-hardened for maximum torsional strength and durability.

    • Manufacturing: Centerless ground for a perfectly consistent outer diameter, ensuring smooth operation and the elimination of surface-level stress risers.

    • Finish: Industrial powder coating for superior corrosion resistance.

    • ⚠️ Technical Installation Notes

  • Measurement is Critical: The 16 1/4" length is specifically for modified or wide-track suspensions. Installing an axle that is too long for your track width will cause it to bottom out inside the CV joints, leading to immediate transmission or hub damage.

  • CV Boot Selection: Because the joint "floats" across a 2 3/8" spline, use high-articulation silicone or heavy-duty rubber CV boots to ensure they do not tear during extreme extension.

  • Lubrication: Use high-moly content CV grease. The floating action requires constant lubrication on the splines to prevent "notching" and ensure the joint slides freely. 

What’s Included

  • Pair of VW IRS axles
  • Spirol Lock circlips to secure the CV joint
