My engine builder was very impressed with this product he confirmed they are the best and strongest single spring he has seen. And they are better then some double springs- further confirmed the spring rate is about 88/90 to set and 200 at 10mm. Awesome product.
Great price always a pleasure to Buy from ZZPerformance always shipped out immediately, fast delivery and if you’re looking to get rid of valve float these are your springs
Had these fitted to my Saab b207xwd for around 6 months now . It’s hitting soft cut limiter 7700 rpm with no issues. These are a great upgrade
I put the springs in and have not ran it yet but the car runs alot better. And it pulls all the way thur the rpm. Definitely if I need more parts I will be looking on zzp
Had the head off the LSJ when I installed these and it was a PITA to install these springs Had to bolt the head to my workbench to prevent it from moving, then use an extended pole to really push pressure down on them because they are so stiff! (which is a good thing) This isn't a job for a newbie, it's difficult but not impossible I recommend a small magnet for the keepers, a small flat blade, and some really stick assembly lube squirted into the top hats. Then stand the keepers straight up and around the valve before pressing down That's the easiest way I could install them Also wear safety glasses....if you slip it could save your eye lol
