Valve Spring Compressor SUM-906784

SUM-906784
This spring compressor is a dream. I first saw one used on U-Tube and could see the obvious upsides. The way it locks down allows your full attention and the use of both hands to play with those keepers and tricky little seals. HOWEVER it's fingers seem to be a few degrees off the best angle because it compresses the retainer off center and I had to improvise a shim deal to prevent it from damaging the new stem seals when releasing the spring pressure. Now maybe I'm doing something wrong but there was no instructions included to help with some of the fine points. ...read more

Good product at good price

Summit RacingSummit Racing Verified Purchase

A good tool with a long lever handle to make spring compression easy. The only reason I didn't give this five stars is that the fingers of the saddle piece that straddles the valve while pressing down on the spring wasn't at quite the proper angle for compressing springs on my Pontiac heads. It would press down unevenly on the spring, causing it to push the valve stem to the side tight against the guide. This was easily fixed by unscrewing the saddle from the tool and putting it in a vice to bend the fingers slightly to reduce the finger angle. Took about two minutes to get right. ...read more

Summit Valve spring compressor SUM-906784

Summit RacingSummit Racing Verified Purchase

This spring compressor works great for replacing springs with the heads installed. I love the way it over-centers compressing the valve springs so you can work hands free while installing the new springs, keepers & locks. It was a good tool to replace the springs in my '64 Lemans convertible for my new Lunati voodoo cam. These springs were very stout (triples) and it compresses them easily. The only issue & the only reason I do not give it 5 stars is for the same problem everyone previously stated. The angle is a little off. I simply put it in a vice and smacked it with a 5lb. sledge to adjust the angle. You could also put shims under it to correct for this. ...read more

Made easy work of my giant solid roller springs. The handle locks and allows use of both hands. The right tool for the job.

makes a difficult job easy

Locks securely making removing and reinstalling valve springs and retainers easy! Very strong too, held up to high strength solid roller springs. Works with 3/8" & 7/16" studs. Did need to tweak compression plate to ensure straight compression though.

As others have said you need to bend the fork to set properly. Works great.

Needs adjustment

It works but needs to be modified otherwise it compresses the spring sideways and there is no way to install the locks. I had to shim it with a folded piece of cardboard just to make it work.

Awesome Spring Compressor

Summit RacingSummit Racing Verified Purchase

SUM-906784
Easy and simple to use. Was set to 7/16 studs when I got it but removed one clip , a pin and it flips over to fit 3/8 studs. That simple!!! You can set it perfectly and it locks down holding pressure on the retainer and springs so you can use both hands if needed.
