FAQ
Q: When should I upgrade to these 95 lb springs?
A: They’re a smart upgrade once you’re consistently running 45+ PSI boost and/or spinning above ~3200 RPM. This helps control valve motion and reduce float at higher load.
Q: Do I need upgraded retainers or keepers?
A: Many builds reuse quality factory hardware, but higher-RPM or higher-spring-rate setups often pair springs with performance retainers/locks for best durability.
Q: Daily driver or towing OK?
A: Yes—these are a common reliability-minded upgrade for tuned/towed trucks that see higher boost while still prioritizing longevity.
