Product Overview
A broken spring, cam swap, lifter repair, or valve-stem seal job does not always require cylinder-head removal. This tool bolts to the rocker mounting points and compresses the spring from above while the valve is supported in the cylinder.
The tool only controls the spring. Compressed air or an approved rope method must prevent the valve from dropping, and offset rocker layouts require careful centering over the retainer.
Confirm engine family, cylinder-head layout, tool mounting holes, and access. Do not confuse Gen III HEMI engines with unrelated older HEMI designs.

Frequently Asked Questions
Q: Can I change springs without removing the head? A: Yes, on compatible heads when each valve is securely supported and the service procedure is followed.
Q: Does it hold the valve up? A: No. The tool compresses the spring; the valve needs separate support.
Q: Will it fit an older 426 HEMI? A: No. The listed application is the modern Gen III engine family.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
