Will –
I bought the valve spring kit a while back and it’s been working great, the springs are good quality and can handle high lift and rpm which is perfect for my engine, overall it’s a solid kit that offers good performance for the price.
Glen –
The Sidewinder valve spring kit is a good product that allows higher valve lift and rpm for more power. I recommend it for anyone looking to increase performance.
Moe –
The Sidewinder valve spring kit was a letdown with inconsistent spring rates, quick failure of two springs, and poor quality control – for a premium brand I expected much better so would not recommend this kit for any performance builds.
Conrad –
Wow, I’m thrilled with this valve spring kit! Installation was a breeze and it really woke up my engine – the performance and quality can’t be beat, especially for the price.
Sidney –
Yo, the Sidewinder valve spring kit is sick for high lift, high rpm builds – it’s got everything you need and the springs can handle big lifts and high speeds without any issues, I put them in and could totally feel the difference right away in power and response, shipping was faster than I thought too, overall they’re a solid kit for the price if you’re building a monster ride.
Elmo –
These valve springs are awesome, they really improved my engine’s performance and got rid of that annoying valve float problem.
Quincy –
This valve spring kit is just your average kit, with common specs and okay performance – nothing to get too excited about.
