Makes spring changes super easy and fast. The springs come packed as shown and it’s a pain to separate them. Wish they made one without the choke cable clamp. Going to cut it off after a few heat cycles.

All the springs are twisted together in the packaging and then shrink sealed! Nearly impossible to separate them without ruining them! Took longer to get the springs out than it did to install the kit...

Cheap material along with missing removable cover screws. Really! How much extra would it cost to add two screws?

The quick change housing is great and works perfectly. The white spring was supposed to be the lightest, but it is exactly the same stiffness as the plain spring. All the other springs were fine. The lightest spring is arguably the most important spring, so it's very disappointing that it is not included in this kit. For this reason, I wish I had purchased the genuine Holley kit (Holley 20-59 Quick Change Vacuum Secondary Housing Kit) and the genuine Holley springs (Holley 20-13 Vacuum Secondary Spring Kit)

Still fine tuning my Holley 4150, but this looks to make the secondaries way easy to tune.

It took less time (but was close) to install this than it did to change a spring, from here on it is all gravy!

Work as claimed. Save so much time and work when changing vacuum secondary spring for Holley carburetor tune.
