Supertech Dual Valve Spring Kit for Opel Vauxhall Z20LET 16V - SPRK-TS1012-Z20 - SPRK-TS1012-Z20

Alright, let’s talk about the Supertech Spring / Retainer Kit—a solid choice for anyone looking to give their Opel or Vauxhall Z20LET 16V a serious upgrade. If you’re the kind of gearhead who loves to tinker and push your engine to new levels, this kit is right up your alley. It’s designed specifically for those who want to ensure their valvetrain is not just functional but optimized for performance.

What sets these springs apart? For starters, they’re dual springs, which means you get a more stable and reliable setup when things start to rev up. With a press seat of 64 at 35.10mm, these springs can handle some serious lift—up to 15.10mm, to be exact. That’s crucial for keeping your valves in check when you're pushing the limits. Plus, with a coil bind of 20.00mm, you won’t have to worry about them bottoming out when the engine's screaming. The spring rate is 9.60 lbs/mm, which strikes a nice balance for spirited driving without compromising comfort too much.

Let’s not forget about the retainers. This kit comes with the RET-TS5.5/T5 retainers and the SPR-TS1012/Z20 springs, along with a seat locator (SEAT-TS-Z20) that makes installation a breeze. Seriously, if you’ve got some mechanical skills, you’ll appreciate how straightforward it is to swap these in.

And here’s the kicker: this kit is tailored for the Opel and Vauxhall Z20LET 16V. So, if that’s what you’re working with, you can be confident that these components will fit like a glove. Just a heads-up, though—if you’re thinking about cranking up the power, these springs are ready to handle it without breaking a sweat.

In short, if you’re looking to overhaul your valvetrain and want something that won’t let you down, the Supertech Spring / Retainer Kit is a no-brainer. It’s all about getting that performance you crave while keeping things reliable and easy to install. Happy wrenching!
