If you're diving into a valvetrain overhaul, you’ll want to check out the Supertech Spring and Retainer kits. These aren’t just any springs; they’re precision-engineered sets designed for those who really care about performance. I’ve used these on my own builds, and let me tell you, they deliver. Whether you're pushing your Honda Civic or Del Sol to the limit, these kits are built to handle the heat and keep your engine running smooth.
What I love about these springs is the balance of quality and value. They’re not just designed for the weekend warrior; they’re crafted for serious enthusiasts who want the best. The single spring design is straightforward but effective. With a seat pressure of 60 at 49.50mm, they’re ready to take on some serious RPMs without breaking a sweat. And if you’re curious about lift, these babies can handle up to 14.90mm, giving you that extra edge you’re looking for in performance.
Now, let’s talk about some specs that matter. The coil bind is at 34.60mm, which means you won’t have to worry about them collapsing under pressure. The rate is a solid 8.50 lbs/mm, so you know they’re going to hold up. Plus, with the RET-H1002/T1 retainers and SPR-H1002S springs, you’re getting a matched set that works seamlessly together. Just keep in mind, if you need a seat locator, the SEAT-HD/F is sold separately.
These kits fit a range of models, specifically the Honda Civic from 1992 to 2005 and the Honda Civic Del Sol from 1993 to 1997. If you’re running a D16Z, D16Y8, or D17 engine, you’re in luck—this kit has got you covered. So if you’re looking to give your ride a serious boost in performance, these Supertech kits are a solid investment. Trust me, your engine will thank you.
