LS Valve Spring Installation & Removal Tool – Billet Aluminum (3/8” Drive)

If you’ve ever fought with a traditional valve spring compressor, this tool will ruin all the others for you.

This LS Valve Spring Installation & Removal Tool bolts directly in place of the factory rocker arm and uses a 3/8” square drive so you can compress the valve spring with a simple ratchet or breaker bar. No awkward clamps, no sketchy leverage — just smooth, controlled compression.

I use this tool every time I do valve springs. It’s significantly faster, easier on the cylinder head, and makes both spring removal and installation stupid simple.

🔧 How It Works:

• Bolts on in place of the rocker arm

• Insert a 3/8” ratchet or breaker bar

• Use the ratchet as a lever to compress the spring

• Remove or install valve keepers with ease

• Works on intake and exhaust valves

🔩 Features:

• Fits LS cylinder heads without offset rocker arms

• Originally designed for cathedral port heads, but works on most LS heads that use standard rocker geometry

• Billet aluminum construction

• Much faster than traditional valve spring compressors

• Easier on the head casting than clamp-style tools

• Ideal for on-head spring swaps

• Available colors:

  • Red

  • Blue

  • Black

⚠️ Notes:

If you do LS valve springs more than once, this tool pays for itself immediately.

Fast. Simple. No frustration.
LS Swap Everything. 🔥
