If you're diving into the world of performance upgrades, you might want to take a good look at the Supertech Spring / Retainer kits. These aren’t just any springs; they’re a solid choice for anyone looking to overhaul their valvetrain without cutting corners. I’ve seen plenty of kits out there, but let me tell you, Supertech really knows how to deliver on performance and durability.
So, what’s the deal with these springs? For starters, they’re dual springs, which means they’re designed to handle some serious lift without losing their cool. You’re looking at a seat pressure of 77 lbs at 34.30mm, which is pretty impressive. They can take a max lift of 14.30mm before hitting coil bind at 20.00mm. The rate sits at a solid 9.60 lbs/mm, making them responsive enough for spirited driving while still being tough enough for daily use.
Here’s a quick breakdown of the specs:
And let’s talk fitment. These kits are compatible with a range of vehicles, especially if you’re working with Mazdas or Fords. Just to give you an idea, they fit everything from the Mazda B-Series (2001-2010) to the Ford Focus (2004-2018). If you own a Mazda Miata from 2006 to 2015, you’re in luck—these springs will fit right in. Here’s a more detailed list:
So, if you’re serious about getting the most out of your engine, these Supertech kits are worth considering. They’re built for enthusiasts who want quality without breaking the bank. Trust me, your engine will thank you for it!
