VINCOOL will provide professional and sincere service. This Valve Spring Compressor Tool will greatly help you!
- Fit all LS engines with 14mm / 18mm diameter spark plug holes
- The 1/4" female NPT can easily be connected to air hose quick connect fittings. 14mm is the standard spark plug size for most vehicles
- while the cylinder head is installed on the engine,you need this tool to install valve springs
- The tool keeps the cylinder with compressed air, causing the valve to remain closed when the valve spring is replaced
- Just thread the tool into the spark plug hole, and fill the cylinder with compressed air
These main components are heat treated to increase their service life

Worked great for my LS build. Took me a sec to figure out, as it did not come with instructions. But tool held up.

Might want to spend more money on a nicer one. Every time I compressed a valve it would shred a little metal because of how cheap it was. It worked enough for one top end build but it’s pretty ruined and I had to flush all the little metal shavings out the top end. For the price it was fine I’ll vacuum and flush the top end but next time I’ll spend double the money and get a better one.

Several problems with this item that are not clear in the description.(1) [MINOR ISSUE] Cannot use with 7/16" rocker studs. It is machined to fit 3/8" rocker studs. I was able to machine the pieces to fit 7/16" studs, which lead me to the next problem...(2) [MAJOR ISSUE] The pieces are milled to fit cylinder heads held on with bolts, not studs. My SBC 350 Gen 1 ARP studs (ARP234-4301) protrude too high, interfering with the aluminum base and steel T pieces. Show stopper for me.(3) [MINOR ISSUE] The piece that caps the valve spring O.D. locator is machines to fit 1.00", but my AFR Eliminator 180 heads have 1.380".The pictures and description do not make these issues clear. Carefully research this tool if you intend to buy. Ultimately, I was not able to use this. According to other reviews, it looks like it works well on factory heads with bolts.Quality of craftsmanship = good

Used this on a 2011 Chevrolet Suburban with an LQ9 5.3L LS motor. Extremely easy to use and fast. I will recommend this to all those doing valve springs on an LS motor.
