BRGMAX snowmobile idler wheels 4-pack 5.63" with 20mm bearings direct-fit for Arctic Cat

BRGMAX 4-pack idler wheels are a direct-fit replacement for many Arctic Cat snowmobiles, each 5.63" in diameter and pre-fitted with a 20mm bearing for fast installation.

These metal idler wheels from BRGMAX are built to restore smooth track motion and dependable support to your snowmobile's rear suspension. Sold as a set of four, the wheels are engineered to match OEM dimensions and fit common Arctic Cat part references, making them a practical service or emergency-repair option. Their complete assembly with 20mm bearings eliminates the need to press bearings separately, saving time during maintenance.

Will these idler wheels fit my Arctic Cat model?

If your snowmobile uses the listed part references, these BRGMAX idler wheels are designed as direct replacements. They match the 5.63-inch outside diameter and come with a 20mm bearing already installed, reducing fitment guesswork.

• Replacement reference: 541-5031 for quick identification.
• Compatible with part numbers: 1604-837, 2604-196, 3604-039, 3604-043, 3604-047, 3604-048, 3604-386, 3604-420, 3604-486, 3604-681, 3604-807.
• Measure existing idlers: 5.63" O.D. and 20mm bearing bore to confirm fit.
• Sold as a set of four to refresh the entire suspension run.

How do these wheels affect ride performance and durability?

The wheels are constructed from metal for enhanced strength and wear resistance compared with lightweight or brittle alternatives. Properly functioning idler wheels keep track tension steady and reduce unwanted vibration, improving overall handling and reducing stress on the suspension components.

• Metal construction resists chipping and deformation under load.
• Preinstalled 20mm bearings reduce friction for smoother track travel.
• Matching all four wheels helps maintain even wear along the track.
• Helps prevent foreign-object damage by keeping track aligned and supported.

What should I expect during installation?

Installation is straightforward because the wheels come complete with bearings already pressed in. You will typically remove the old idlers, transfer any spacers or collars, and mount the new wheels to the same shafts—no bearing-pressing step required unless your machine uses different spacers.

• Pre-assembled wheels save time—no bearing press needed in most cases.
• Use factory torque specs and any original spacers for proper alignment.
• Inspect shafts and hardware for wear before reassembly.
• Contact BRGMAX support within 24 hours for fitment questions.

How do I choose between replacing one wheel versus the whole set?

Replacing in matched sets is recommended because wheels wear together; mixing new and old idlers can create uneven track tension and premature wear. If only one wheel shows damage, a single replacement will work temporarily, but a full set provides the most consistent performance.

• Full set restores uniform ride characteristics and track alignment.
• Single-wheel replacement is a short-term repair option.
• Evaluate wheel surfaces and bearings for rust, gouges, or flat spots.
• Choosing four at once reduces downtime and maintenance frequency.

Who is this for: BRGMAX 5.63" idler wheels are aimed at Arctic Cat owners, snowmobile mechanics, and DIY riders who need reliable, ready-to-install replacement idlers. They suit anyone restoring suspension performance, preparing a machine for the season, or replacing worn idlers to maintain safe, predictable track tension.
