M MATI Front Left & Right Brake Caliper Assembly for Polaris ATV Sportsman/Magnum Pair — OEM Fit, Pre-Assembled with Pads

M MATI front left and right brake caliper assemblies are a direct-replacement set engineered to restore braking performance on compatible Polaris ATVs without modifying the original mounting.

These two-piece caliper assemblies (left and right) match Polaris OEM mounting points and thread standards so they bolt in using the stock hardware. Each caliper arrives pre-assembled with pads and the correct bracket geometry, offering a straightforward swap for a range of Polaris models from late 1990s through mid-2000s. The units are constructed from robust materials to withstand off-road conditions and are supplied as a pair so both front sides are renewed at once.

Which Polaris models and years do these calipers fit?

The assemblies are designed to fit numerous Polaris ATVs across model families including Sportsman, Magnum, Xplorer, Xpedition, Ranger and others. Compatibility covers many 1999–2005 year models — always verify specific model and year before ordering. The listing references many manufacturer and replacement part numbers so you can cross-check against your vehicle.

• Common fits: Sportsman 335/400/500/600/700, Magnum 325/330/500, Xplorer 400, Xpedition 425
• Also fits: Ranger 500, Big Boss INT'L, Worker 500 and several 6x6/4x4 variants

How easy is installation and what hardware is required?

Installation is intended to be bolt-on using the original mounting points and American-standard thread sizes; no custom machining is required. The calipers come with the mounting bracket and pads in place so most installations are simple replacements for a mechanic or competent DIYer. Basic hand tools and a torque wrench are typically all that’s needed for a safe install.

• Includes: front left caliper and front right caliper, both pre-assembled
• Tools: common hand tools, torque wrench, brake fluid for bleed if needed
• Time: most front caliper swaps take about 1–2 hours for both sides

What materials and quality features are included?

The calipers are made from durable metal alloys chosen for corrosion resistance and strength under off-road stress. They are produced to match OEM specifications for fit and function, including correct pad fitment and threaded mounting points. The assemblies are built for long-term use and designed to accept standard replacement pads when service is required.

• Construction: sturdy metal caliper bodies with protective finish
• Fitment: manufactured to OEM spec for direct replacement
• Serviceability: standard brake pads and hardware compatible for future maintenance

If you’re unsure about compatibility, consult your Polaris parts diagram or match one of the referenced manufacturer part numbers. The product listing includes cross-reference numbers to help confirm fit for many ATV variants.
