If you’re diving into a serious valvetrain overhaul, the Supertech Spring/Retainer kits are where it’s at. These kits are crafted for folks who really care about performance and want to get the most out of their ride. I’ve had my hands on these, and let me tell you, they deliver. You’re not just getting a bunch of parts; you’re getting a precision-matched set that’s built for those who appreciate the finer details of engine performance.
What’s cool about these springs is that they’re dual springs, which means you’re getting that extra stability and control, especially when you’re pushing your engine to the limits. The press seat is rated at 92lbs at 39.6mm, which is solid for keeping everything in check. And if you’re worried about max lift, these babies can handle up to 14.9mm without breaking a sweat. That’s crucial when you’re trying to squeeze every last bit of power from your setup.
Now, let’s talk about the coil bind. At 24.7mm, you’ve got a good margin to work with, and the rate of 12.5lbs/mm means you’re getting a balanced feel that’s not too stiff but still responsive. The retainers are the RET-M65/T1, and they fit perfectly with the SPR-M1007D springs, ensuring everything works together seamlessly. Plus, they come with seat locators and valve seals that are designed to fit right into your setup without any hassle.
These kits are a perfect match for a few models, including the Eagle Talon from '95 to '98, the Mitsubishi Eclipse from '95 to '99, and the Mitsubishi Lancer from '03 to '06. So if you’re rolling in one of those rides, you’re in luck. Overall, if you’re looking to upgrade your valvetrain and really feel the difference in performance, you can’t go wrong with the Supertech Spring/Retainer kits. They’re built to last and designed for those who know what they want from their engine.
