Kelford KVS253 Valve Spring Set for 3.5L Ecoboost V6 Ford Gen 2, Performance Upgrade - KVS253

If you're looking to really unleash the potential of your Ford Gen 2 3.5 litre V6 Ecoboost, you might want to check out the Kelford Valve Spring Set. I?ve had my hands on these PACALOY beehive springs, and let me tell you, they?re a game changer for anyone who's serious about performance upgrades.

These springs are specifically designed to work seamlessly with high-performance camshaft upgrades and are perfect for those running high boost applications. The engineering behind them is solid; they?ve got a seat pressure of 90 lbs, which means they?re built to handle some serious power without flinching. The installed height is at 43.0mm, and they deliver a strong 246 lbs at 13mm lift. That?s some serious muscle right there!

One of the things I really appreciate is the coil bind at 25.0mm. It gives you that extra bit of assurance when you?re pushing your engine to its limits. You can feel confident that these springs will hold up under pressure, whether you?re tearing up the track or just cruising around town.

These springs fit perfectly in the Ford F-150 models from 2017 to 2020, so if you?re looking to boost your ride?s performance, the Kelford Valve Spring Set is definitely worth considering. You?ll notice the difference in responsiveness and power delivery right away. It?s a solid upgrade for any enthusiast who wants to get the most out of their Ecoboost V6.
