Bruce –
The Sidewinder 650 spring kit seems pretty decent for a budget upgrade, it went in easy and has held up for 500 miles of weekend cruising with my bigger cams.
Clay –
The Sidewinder springs are high quality parts that perform great in my big cam Twin Cam build. Even with the shipping delay, I’d buy these again for a high-revving motor.
Rod –
These springs from XYZ handle my Twin Cam’s high lift cam nicely. Install was easy and so far performance has been impressive.
Archie –
These valve springs are a great upgrade if you want more lift for higher rpm power with a performance cam in your Twin Cam engine.
Todd –
I’m thrilled with my new Sidewinder valve spring kit which really wakes up my engine compared to other kits I’ve tried. If you want to upgrade to .650 lift springs, I’d definitely recommend giving these a shot.
Nick –
I recently put some Sidewinder valve springs in my Twin Cam and I’m thrilled with how much more power I’m getting throughout the rpm range, the quality is top notch too.
