Chevrolet Impala Window Crank Handle Guide: 1958-1966
Replace your worn, stripped, or broken window crank handles to restore your classic Impala's interior function and style.
- The most common failure is stripped splines, which causes the handle to spin without moving the window.
- Aftermarket options include premium billet aluminum handles from brands like Lokar or OE-style die-cast reproductions.
- Be cautious with low-cost reproduction handles, as some have fitment issues due to poorly made splines.
- Replacement is a very easy DIY job that requires removing a simple C-clip behind the handle.
Signs of a Failing Window Crank Handle
On a classic car like the 1958-1966 Impala, window crank handles fail from decades of use. The most common issue is stripped splines inside the handle, causing it to spin freely without moving the window. You might also find the knob has broken off, or the handle itself is cracked. Often, the chrome finish becomes pitted and worn, detracting from your interior's appearance.
Choosing the Right Aftermarket Handle
Since new original GM parts are not available, you'll be choosing from aftermarket options. These fall into two main categories: premium custom handles and standard OE-style reproductions.
Premium Custom: Billet Aluminum
For owners looking for a high-end, durable upgrade with a modern custom look, billet aluminum handles are the top choice. Lokar is a leading brand in this category.
- Material: Machined from solid blocks of billet aluminum for superior strength and a precise fit.
- Quality: Known for excellent craftsmanship, made in the USA, and backed by a lifetime warranty.
- Design: Lokar offers various styles (like windowed or lakester) and finishes (polished or black) to match other custom interior parts. They feature a splined design for fine adjustment of the handle's position without unsightly set screws.
Standard Reproduction: OE-Style
If you want to maintain a factory-original look, OE-style reproduction handles are available. These are typically made from die-cast zinc with a chrome finish and a plastic or chrome knob, designed to mimic the original appearance.
A Note on Reproduction Part Quality
Be aware that the quality of reproduction handles can vary. Some owners have reported issues with lower-cost, unbranded parts having poorly cast splines that do not engage the regulator shaft correctly. This can cause the new handle to feel loose or slip after a short time. Choosing a reputable reproduction brand like OER can improve the chances of a good fit.
Installation Overview
Replacing a window crank handle is a simple DIY job that takes only a few minutes per door. The handle is held onto the regulator shaft by a small C-shaped clip.
- Push the door panel in around the base of the handle to expose the clip.
- Use a window crank removal tool to push the clip off.
- Pro Tip: If you don't have the special tool, you can often hook the ends of the clip with a shop rag and pull it off.
- Once the clip is off, the handle and the protective washer behind it will slide right off the shaft.
- To install the new handle, place the clip onto the handle first, then simply align the splines and push it firmly onto the shaft until it clicks into place.

Frequently Asked Questions
Do I need a special tool to replace my window crank?
A window crank removal tool makes the job easier and is inexpensive, but it's not strictly necessary. Many people successfully use a shop rag, two small hooks, or a paper clip to remove the retaining clip.
Why do my new reproduction handles feel loose?
This is a common complaint with some lower-quality reproduction parts. The splines inside the handle may not be deep enough or cast correctly to fully engage the regulator shaft, causing a sloppy fit. Consider higher-quality reproductions or a billet aluminum option for a more secure fit.
Will a handle from a different GM car fit my Impala?
Yes, in many cases. GM used the same splined shaft design on its window regulators for many decades across various models. While the handle's appearance may differ, the fitment on the shaft is often the same. However, for a correct look, it's best to buy a handle specified for your Impala's year range.
What is the difference between a window crank and a vent window crank?
They are different parts. The main window crank is larger and operates the main side glass. The vent window crank is smaller and operates the small triangular vent window. They attach to different regulators and are not interchangeable, though brands like Lokar offer matching styles for both.
Technical Specifications
The primary specification is the GM-style splined shaft attachment, which was common from the 1940s to the 1980s. Handles are held in place with a C-clip.
