Product description

Ferrea Valve Spring Kits bring together some of the best valvetrain components to help maximise performance specific to your engine application. Ferrea knowledge and expertise have allowed them to build valve spring kits using components of premium quality and durability that exceed standard industry requirements.

 

  • Valve Springs – Ferrea Valve Springs provide the stability needed for high lift, high RPM racing engines, while minimising the load loss for today’s aggressive valvetrain combinations. Ferrea springs are heat-treated and stress relieved, which dramatically increases the spring’s life.
  • Retainers – Ferrea retainers are fully heat-treated and finished to exact tolerances, adding strength while offering a weight reduction over conventional steel retainers. Precision CNC-machined from aerospace quality titanium materials.
  • Seat Locators – Ferrea Seat locators are fully CNC machined in-house from 4140 chromoly steel alloy for different applications. Heat treatment consists of a hard Nitrided surface for unmatched toughness and anti-wear characteristics.
  • Valve Locks – Ferrea Valve Locks are manufactured from high quality 4140 chromoly bar stock and machined to exact tolerances. The locks are heat-treated for a maximum strength and finished with the black oxide for an attractive appearance.

This kit contains:

 

  • Dual Springs (24)
  • Titanium Retainers (24)
  • Seat Locators (24)
  • Valve Locks (24)

Excellent fit and value - recommended buy
Size: 3+12+12+2+1 pack
I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake. Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha. I can recommend getting this kit for your robot vacuum, if it's the right set for your model.

Good option for an aftermarket replacement solution.
Size: 3+12+12+2+1 pack
I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.

Eufy Brushes wear out with daily use
Size: 4 Pack
These brushes help the Eufy continue to run efficiently. I have 2 dogs and run 2 Eufies daily. It is surprising how much sand, dust, gravel and hair gets vacuumed. My furniture isn't as dusty and my floor doesn't need mopping as often.
