Unmatched Valve Control

The lifeblood of any performance engine is valve control, and this kit delivers in spades. With spring specs of 155 lbs @ 1.780″, 380 lbs @ 1.180″, and a whopping 400 lbs @ 1.130″, you’re looking at stability that doesn’t flinch under extreme RPMs or power loads. The coil bind at 1.070″ is engineered to perfection, giving you confidence no matter how hard you push that throttle.

Whether you’re running a nasty N/A stroker, a big-boost turbo build, or just a stout cammed street car, keeping your valves in check at high RPM is crucial. And this dual-spring setup? It’s like having a bouncer for your valvetrain—rowdy but controlled.

Top-Shelf Components

Brian Tooley Racing doesn’t mess around with second-rate materials, and neither should you. This kit comes packed with:

• Dual polished springs: Designed for maximum durability and consistency.
• Titanium or chromoly steel retainers: Light yet strong, the perfect combo for high-performance applications.
• Valve locks and seals: Built to keep things tight and leak-free.

Oh, and did I mention it’s all designed to work seamlessly with stock rocker arms? That’s right, no extra surprises or costly modifications needed. This is a drop-in solution for 15° LS heads, and if you’ve got LS7 heads, just toss in a .045″ shim, and you’re good to go.

No-Nonsense Installation

Even if you’re not wrenching full-time, this kit is as user-friendly as it gets. With everything included, there’s no chasing down extra parts or playing compatibility roulette. Whether you’re a seasoned builder or tackling your first LS upgrade, the BTR Platinum Dual Spring Kit lets you get the job done without pulling your hair out.

Proven Performance

Here’s the deal: it’s been tried, tested, and thrashed in everything from daily drivers to 1,000 hp turbo monsters. This kit’s been engineered to withstand the abuse we all know these engines can dish out. High-lift cams demand precision and durability, and the SK001 delivers both in spades.

So whether you’re hunting 600 hp with a naturally aspirated build or turning up the boost on your turbo setup, this spring kit is the MVP of your valvetrain upgrade. It’ll handle the heat, the abuse, and the late-night dyno sessions—no sweat.
