Nice Apollo SPAMG091A00 Spring Kit for M3BAR, M5BAR and PARK / PBar Barriers
The Nice Apollo SPAMG091A00 spring kit is a counterbalance service kit for smaller M-BAR barrier systems such as M3BAR and M5BAR, with supporting references also tying it to PARK / PBar-style applications. Barrier springs do more than make the arm easier to lift; they reduce load on the motor and gearbox, help control speed, and keep the arm from slamming or dragging through travel. A weak, broken, or incorrect spring can make the barrier run hard, stop on obstruction errors, drift, or wear the drive system prematurely. Because spring balance depends on arm length and accessories, this part must be matched to the barrier model and the installed arm setup.
Common replacement signs include a broken spring, heavy manual arm movement, arm drift, uneven travel, motor strain, slow operation, or poor balance after a new arm or accessory was installed.

Technician Note
After replacing a spring kit, the barrier arm must be balanced according to the operator manual. Adding lights, rubber edge strips, reflectors, or a longer boom can change the correct spring setting.
Before Ordering Checklist
- Confirm whether the barrier is M3BAR, M5BAR, or a supported PARK / PBar model.
- Verify arm length and installed accessories.
- Compare the original spring kit number to SPAMG091A00.
- Check the balance chart and spring mounting hole positions.
- Do not install M7BAR or LBAR springs on an M3BAR/M5BAR unless the chart specifically calls for it.
Professional Advisory
Barrier spring service can be hazardous because springs are under load. A qualified gate technician should handle spring replacement, balance adjustment, and testing if the arm is heavy or the operator is in active service.
Important Ordering Warnings
Spring kits are not chosen by appearance alone. The wrong spring can overload the operator or make the barrier arm unsafe to release manually.
Product Questions & Answers
Which operators commonly use SPAMG091A00?
SPAMG091A00 is commonly associated with M3BAR and M5BAR barrier operators, and some references also list PARK / PBar applications when confirmed by parts documentation.
Is this the correct spring for M7BAR?
No. M7BAR commonly uses SPAMG092A00, which should be kept separate from SPAMG091A00.
Is this the correct spring for LBAR?
No. LBAR commonly uses SPAMG093A00, not the M3BAR/M5BAR spring kit.
Why does arm length matter?
Longer arms and added accessories change the counterbalance load, so the correct spring and adjustment position must match the installation.
What happens if the spring is weak or broken?
The operator may run hard, move slowly, drift, stop on errors, or place extra load on the motor and gearbox.
