Product Details

The Proform Parts 66784 Valve Spring Compressor is an on-engine stud-mounted tool designed for quick and easy valve spring removal without disassembling the entire engine. This professional-grade compressor mounts directly to rocker arm studs, allowing technicians to service valve springs, replace valve stem seals, or perform valve keeper maintenance while the cylinder head remains installed on the engine.

Key Features:

  • Compatible with both 3/8 inch and 7/16 inch rocker arm studs for versatile application
  • On-engine design eliminates the need for cylinder head removal, saving significant time and labor
  • Stud-mounted configuration provides stable, secure compression for safe valve keeper removal
  • Durable construction ensures reliable performance for professional and enthusiast use
  • Simple operation: compress the coil spring, remove valve keepers, and release slowly

This valve spring compressor is an essential tool for engine builders, mechanics, and DIY enthusiasts who need to service valve train components efficiently. Perfect for checking valve spring condition, replacing worn springs, or installing new valve stem seals without the expense and complexity of removing the cylinder heads.

Awesome, thanks!

Product exactly as stated but once again..... All my items were shown in stock, my card was charged for full amount and yet again my order trickles in over several days in several shipments.

I like how these headlight look , i can not wait to see how the output is on them. 4 stars for now (:

Great!

GREAT THANKS

order received within time that was expected and as described.

great pricing and received my purchase quickly. the box was a bit torn up, but the contents were fine.

Lowest price I can find! Sent tracking number via FedEx without trouble! Would recommend!

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!

Quick and easy

easy enough so far

Autoplicity had the lowest price online for the product I needed. I will definitely buy from them again.

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>

Very easy to order on line and excellent communication, very good price.
