Rear Main Seal air‑cooled 911s (930, 964, 993)

🐎 DaringColt Rear Main Seal Fitment Kit:

For the legends tinkering with air‑cooled 911s (930, 964, 993), here’s a 3-piece tool set designed to nail the rear main seal fitment every time no mucking about.

• Centering guide: bolts straight to the crank using stock hardware, keeping the seal bang‑on target.

• Punch #1: seats the seal flush with the case clean, precise, no drama.

• Punch #2: drops it under flush by 1 mm, perfect if your crank surface has seen a few too many laps.

How to use:

Care must be taken when using this tool. While it’s designed to make seal installation as easy as possible, incorrect use can still damage the seal or engine. DaringColt accepts no responsibility for misuse. Always confirm with digital calipers or another measuring device to ensure the seal is installed at the correct depth.

Built tough:

The tool is 3D printed from hard, black plastic, solid, durable, and ready for repeated use. It’s aimed at DIYers and hobbyists thanks to its low cost compared to the official Porsche tool, but it’s equally at home in small independent garages since it can be reused many times without damage.
