How Many Springs Should a Strat Tremolo Have? Three vs. Five, From the Bench
Short answer: use the fewest springs that hold the bridge plate where you want it with your strings tuned to pitch. For most players who actually use the bar, that is three. Five springs aren't wrong, but they are a decision to stop using the tremolo as a vibrato, and many players make that decision without realizing it.
It's a common story: a Strat has five springs hooked up, the owner says the bar "feels stiff," and the fix is often just taking two springs off and backing out the claw screws.
What the springs are actually doing
A Strat tremolo is a tug-of-war. Six strings pull the bridge plate up and toward the neck. The springs in the back cavity pull the tremolo block the other way. When the two forces balance, the plate sits still and the guitar stays in tune. Press the bar and you tip that balance on purpose.
Illustration: the strings and springs balance around the pivot screws. It shows the general mechanism, not any specific guitar.
Everything else follows from that. More springs, or tighter claw screws, mean more tension pulling the plate down toward the body. Heavier strings pull harder the other way, so they need more spring tension to hold the same position. Raising the saddles changes the leverage too, which is why a big action change can move your float. It all interacts, so check the rest whenever you change one.
Three springs vs. five: what you'll feel
Going from three springs to four is a noticeable jump in stiffness, and five is stiffer still. Players on the forums who tried five often describe it as nearly locking the bridge in place. The practical effect is less subtle, shimmery vibrato and more resistance in the bar. In exchange you get a bridge that is harder to knock out of tune with a stray palm.
Three springs give you the classic feel: a bar that moves easily, gentle vibrato, and some room to pull up as well as dive. The trade-off is that the bridge needs to be set correctly, and a broken or stretched string will shift the tuning on the remaining strings more.
Two things I'd keep in mind:
- String gauge matters. Players on heavy sets often need more spring tension to keep the plate level. Players on light sets usually need less, and often find five springs unusable.
- Every guitar is a little different. Spring behavior varies between guitars and between spring brands, so the same count can feel different from one Strat to the next.
Does the spring count change your tone?
This is the part that gets argued about online. Some players swear five springs plus a tight bridge adds sustain or snap, and some hear a little spring ring when the guitar is unplugged. Most of the experienced players I've read hear no difference through an amp, and that matches what I'd expect to hear. I can't point to a measurement that settles it, so I'll just say this: if you chose five springs for tone, you may be paying for it in feel. If you want a locked-down bridge, the real fix is a decked or blocked tremolo, and I cover that in Should You Float, Deck, or Block Your Strat Tremolo?
What I see in a real cavity
A good example is the 2022 Fender American Vintage II '57 Stratocaster I currently have. It has no back cover, so the spring cavity is open to view, and in my listing photo I count five springs hooked to the claw.

That guitar passed my inspection with spot-on intonation and a comfortable medium action, so five springs is clearly working for how it is set up. The point is not that five is wrong. It is that the count you find in the cavity tells you how the last person wanted the guitar to behave.
How to find the right number on your own Strat
- Tune up and check where the plate sits. A commonly quoted Fender spec is about 1/8 inch of lift at the back edge of the plate for a floating setup. A decked plate works for down-only bends.
- Change one thing at a time. Add or remove a spring, then re-tune and adjust the claw until the plate returns to where it was. The bridge position stays the same, so your intonation should not change.
- Use the claw to fine-tune. Tightening the screws pulls the plate down; loosening lets it rise. If you have run out of adjustment, you probably need a different spring count.
- Re-check after any string gauge change. New gauge, new balance. I wrote about this in If You Change String Gauge, Do You Need a New Setup?
If your tremolo is a two-point design rather than a six-screw vintage unit, the balance works the same way but the pivot is different. My comparison in 2-Point vs. 6-Point Strat Tremolo explains what changes.
My take
If you use the bar even a little, start with three springs and the claw screws set so the plate floats slightly. If you never touch the bar, five springs and a decked bridge is a perfectly honest setup, but at that point consider blocking it and stop paying in stiffness for stability you could get another way.
If you are shopping for a used Strat, open the back cover and look. Springs that are rusty, stretched, or mismatched in length are a sign of a guitar that has been adjusted by guessing. You can browse what I have in stock in the guitars in stock collection.
FAQ
How many springs should a Stratocaster tremolo have?
Three is the usual starting point for players who use the bar. Four or five make the tremolo much stiffer and are better suited to heavy strings or players who rarely use it.
Do more tremolo springs make a Strat stay in tune better?
They can, because a stiffer bridge is harder to move by accident. But a properly set up three-spring tremolo with a good nut should stay in tune fine for normal playing.
Can I change the number of springs myself?
Yes, it is a reversible job that needs only a screwdriver. Re-tune and adjust the claw after each change, and keep the original springs in case you want to go back.
Do tremolo springs affect tone?
Most players hear no difference through an amp. A few report small changes in sustain with a tighter bridge, but it is a debated point and I would not choose a spring count for tone alone.
