Ravin Crossbow Maintenance:
The Real Replacement Intervals
Inspection basics, plus the specific numbers Ravin actually publishes — string/cable replacement intervals that vary by model, and the serving fluid spec most guides skip entirely.

Most crossbow maintenance advice is generic — "check your manual" without saying what the manual actually says. Ravin publishes real numbers: strings and cables should be replaced every 2 years or a set shot count, whichever comes first — and that shot count is different depending on which Ravin you own. Here's the inspection basics, plus the specifics.
Fast Checklist (60 Seconds, Before Every Session)
- Check string/serving for fray, separation, or glazing.
- Check limbs (top/bottom/edges) for cracks or splintering.
- Verify all hardware is snug — stirrup, stock, scope mount, quiver mount.
- Wipe the rail/flight track clean.
- Confirm arrows are straight, fletching intact, broadheads tight.
String & Cable Replacement — By Model
Ravin's own guidance: replace strings and cables every 2 years, or sooner based on shot count — and that count isn't the same across the lineup.
| Your Model | Replace Every | String & Cable Set | Price |
|---|---|---|---|
| R9, R10, R10X, R10 Pro, R10X Pro, R15, R20, R29, R29X, LR | 2 years or 400 shots | R190 | $129.99 |
| R26, R26X, R5X | 2 years or 400 shots | R191 | $129.99 |
| R470, R470 XK7, R470E XK7, R500 series (all variants) | 2 years or 200 shots | R192 | $129.99 |
| R18 | 2 years or 200 shots | R193 | $129.99 |
Serving Fluid: The Spec Most Guides Skip

A non-wax polymeric lubricant applied specifically to the center serving of the string — not the rail, not the limbs. Odor-free and waterproof. Ravin's own guidance: apply at least once a year, or before use in weather below 32°F.

String + Serving
The serving is the wear surface. Watch for fraying or fuzzing you can catch with a fingernail, separation or unwrapping in the center serving, glazing or burn marks from friction, or uneven wear that wasn't there last session.
Limbs + Riser
Damage here is a stop condition — don't take "one more shot." Watch for hairline cracks, splinters, delamination, odd stress lines that grow session to session, or new creaks/pops under load.
Rail / Flight Track
Grit acts like sandpaper on the rail; over-lubing traps grit. Watch for visible grit or metal shavings, nicks or sharp edges that can cut the serving, and build-up at the latch/trigger area.
Hardware + Optics
Loose parts cause "mystery" accuracy problems. Check scope rings and base screws (a shift here means a drifting zero), stirrup/stock bolts, and quiver mount hardware before assuming your ammo or tune is the problem.

When to Stop Immediately
Bottom Line
The inspection habits matter more than any single product — check hardware, string, and limbs before every session. But when it's actually time to replace strings and cables, match the correct set to your exact model (they are not interchangeable across model families), and remember Ravin's own numbers: 400 shots for the R10/R26/R29/LR families, but only 200 shots for the R18 and R470/R500 series — both capped at 2 years regardless of shot count.
Frequently Asked Questions
How often should I replace my Ravin's string and cables?
Ravin recommends replacement every 2 years or after a set number of shots, whichever comes first. That count is 400 shots for the R9/R10/R10X/R15/R20/R29/R29X/LR family and the R26/R26X/R5X family, but only 200 shots for the R18 and the R470/R500 series.
Can I replace Ravin strings and cables myself?
Ravin's own instructions recommend having this done at a pro shop or the Ravin Service Department, using only the Ravin Press — and explicitly warn against using the Ravin Bow Press on any other crossbow brand. Read the included instructions and warnings carefully before attempting it yourself.
Is Ravin Serving Fluid the same as rail lube?
No. Serving Fluid is a non-wax polymeric lubricant applied specifically to the center serving of the string, not the rail. Apply it at least once a year, or before use in weather below 32°F.
What's the most common cause of "mystery" accuracy problems?
Loose hardware and mount movement, especially on optics, is a common cause, followed by serving wear and rail contamination. If groups suddenly open up, inspect and tighten hardware before changing arrows or chasing a tune issue.
What should I do if I see a small limb crack?
Stop shooting immediately and follow the manufacturer's service process. Limb damage is a safety risk, not a cosmetic issue.
