Porsche 944 Clutch Assist Spring Part Number: Complete Guide

If you own a Porsche 944, you know that even small components can have a big impact on driving experience. The clutch assist spring is one such part—a simple coil spring that reduces pedal effort and smooths engagement. When it fails, the clutch pedal may feel heavy or inconsistent, and finding the right replacement starts with the correct part number. This guide covers OEM and aftermarket options, how to identify the right spring for your 944, and what to expect during replacement.

What Is the Clutch Assist Spring and What Does It Do?

The clutch assist spring is located inside the clutch pedal assembly. It works with the clutch master cylinder to reduce the force needed to depress the pedal. Over time, the spring can fatigue, break, or lose tension, leading to a stiffer pedal or a pedal that doesn’t return fully. The spring is specific to the 944 platform and is not interchangeable with springs from other Porsche models.

Why the Correct Part Number Matters

Using the wrong spring can cause improper pedal feel, premature wear of other clutch components, or even difficulty engaging the clutch. The Porsche 944 went through several updates during its production run (1982–1991), and the assist spring changed accordingly. While some aftermarket parts may claim universal fit, the safest route is to match the OEM or equivalent part number to your car’s VIN or build date.

OEM Part Numbers for Porsche 944 Clutch Assist Spring

Porsche used several part numbers for the clutch assist spring across different years and transmissions. Here are the most common OEM numbers:

944 116 059 00

This is the early production spring, used on 1982–1985 944 models with the original 2.5L engine and 5-speed manual transmission. It has a specific coil diameter and length. If you have an early car, this is likely what you need.

944 116 059 01

Introduced around 1985.5 (the “late” 944), this spring has a slightly different tension rate to match the revised clutch pedal design. It fits 1985.5–1987 non-turbo and 1986–1988 944 Turbo models. Many owners find that this spring also works well as an upgrade for earlier cars if the clutch pedal feels too light.

944 116 059 02

A later supersession that replaced both previous numbers in some markets. Check with a Porsche dealer or parts specialist to confirm if this is the current production part. If in doubt, provide your VIN to get the correct match.

Always verify with a parts diagram—the spring sits behind the pedal and is held in place by a retaining clip. Replacing it is straightforward but requires careful removal of the clip to avoid damage.

Aftermarket Alternatives

If OEM springs are unavailable or too expensive, several aftermarket manufacturers offer replacements that meet or exceed OEM specifications.

URO Parts

URO makes a direct replacement for the 944 clutch assist spring (part number 944 116 059 00). It is made from high-tensile spring steel and is priced competitively. Many DIYers report good results, though some note that the finish is not as polished as OEM.

Sachs

Sachs is a well-known OEM supplier for clutch components across many European brands. They offer an assist spring (Sachs 2294 600 028) that matches the 944 application. It is often slightly more expensive but comes with a reputation for durability.

Febi

Febi Bilstein also produces a replacement (Febi 10196) that fits 1982–1991 944 models. It is a budget-friendly option that generally works fine, though some users have reported a slightly lighter pedal than OEM.

When choosing aftermarket, stick with brands that explicitly list the Porsche 944 in their fitment. Avoid generic or universal springs, as they may not have the correct tension or dimensions.

Symptoms of a Failing Clutch Assist Spring

A worn or broken spring can manifest in several ways:

• Heavy clutch pedal – The spring no longer provides assist, so the pedal feels significantly stiffer.
• Inconsistent engagement – The clutch may grab abruptly or slip because the pedal doesn’t return smoothly.
• Creaking or popping – A broken spring can make noise inside the cabin when the pedal is depressed.
• Pedal stays partially down – In rare cases, a broken spring can jam the pedal, requiring manual return.

If you notice any of these symptoms, inspect the spring before blaming the master or slave cylinder. A simple spring replacement can restore proper pedal feel for under $20.

Steps to Replace the Clutch Assist Spring

Replacing the spring is a DIY-friendly job that takes about 30 minutes. Here’s a general outline:

1. Remove the lower dash panel under the steering wheel to access the pedal assembly.
2. Locate the clutch pedal and the assist spring. It is attached to a bracket and the pedal arm.
3. Use a small flathead screwdriver to pry off the retaining clip that holds the spring in place. Be careful—the clip can fly off.
4. Remove the old spring and compare it to the new one (length, coil count, diameter).
5. Install the new spring in the same orientation. The spring may be pre-loaded, so compress it slightly to fit.
6. Reinstall the retaining clip and ensure it seats fully in its groove.
7. Test the pedal before reassembling the dash. Pump the clutch several times to confirm smooth operation.

Note: If the spring feels too tight or too loose, double-check the part number. An incorrect spring can cause binding or insufficient assist.

Where to Buy

You can purchase the correct spring from:

• Porsche dealership parts departments – They can pull up the exact number using your VIN, but expect higher prices.
• Specialist online Porsche parts retailers – Sites like Pelican Parts, ECS Tuning, or FCP Euro stock both OEM and aftermarket options. These often provide detailed fitment guides and diagrams.
• Local auto parts stores – Some may carry Sachs or Febi springs if they have a European car section, but stock is spotty.

Avoid generic hardware store springs. They are not designed for automotive pedal applications and may fail quickly.

Final Recommendation

For most owners, the best choice is to buy the OEM spring that matches your 944’s production date. Use VIN lookup to determine whether you need the early (00) or late (01) version. If cost is a concern, aftermarket options from Sachs or Febi are reliable alternatives. Always inspect the retaining clip and pedal bracket for wear when replacing the spring—a few extra dollars on those small parts can prevent future issues. With the right part number and a basic tool set, you can restore your 944’s clutch to its original light, precise feel.
