Product Details

The Manley 221421-16 Nextek dual valve springs are engineered for high-performance engine applications requiring superior valvetrain control. These springs feature a 1.324-inch outer diameter and utilize Manley's advanced Nextek material technology for enhanced durability and resistance to valve float at elevated RPM.

Key Features:

  • Nextek construction provides superior strength and heat resistance compared to conventional chrome silicon materials
  • Dual spring design offers increased load capacity and reliability
  • 1.324" outer diameter fits a wide range of performance cylinder heads
  • Precision wound for consistent pressure characteristics
  • Ideal for street performance and racing applications

Manley Performance valve springs are manufactured to exacting tolerances to ensure proper valve control and extended service life. Each spring is tested to meet strict quality standards for load rate, installed height, and coil bind specifications.

I was having difficulty finding EGR Fender Flares that were available, but Autoplicity not only had the exact set I needed but had them at the lowest price I'd seen and had super fast shipping - thank you Autoplicity!

Quick and easy. Could have left or right side in description though. Other than that 1 phone call cleared up the left and right confusion and placed my order. Great service. I even used again for my rear Lateral arms I just purchased

So far the order seems to be fine, lets just wait for the part.

Thankyou so much

very good so far. waiting to see how delivery goes. thanks

Easy ordering great price.

Great shopping experience except I did not receive the discount promised by the web site because I could not find any place to enter the coupon code during check out. Otherwise I'm glad to find your site. One other small issue. I did not receive any trac

Autoplicity has great prices on all your car modification needs.

Had exactly what I wanted. Shopping cart did not have an update button for new quantity

So far I am happy with Autoplicity's order status updates. I like when shipments are in process and with the updates I know progress is happening. When an order doesn't seem to be moving along a customer wonders what the hold up is. Well so far I don't have to wonder which makes me more patient in waiting for my order. Thank you, I will explore Autoplicity's website for more cool stuff for my car.
