We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • 2000–2006 Polaris Trail Blazer 250

Product Overview

A Trail Blazer opened for piston service, low compression, a leaking base joint, or head-gasket trouble needs new seals. Gaskets cannot correct a warped head, scored bore, damaged piston, crank seal leak, lean carburetion, oiling fault, or cooling problem.

The package typically covers the head, cylinder base, and exhaust joints shown. Verify bore size and every opening because 72 mm, 73.5 mm, and 74 mm gasket families exist for Polaris 250 engines.

Key Features & Performance

  • Top-end sealing package for matching Trail Blazer 250 engines
  • Supports piston, cylinder, or compression repair
  • Bore and gasket material must be matched before assembly

Common Uses

  • Resealing the cylinder during piston replacement
  • Repairing compression leakage after surface checks
  • Completing a two-stroke top-end overhaul

  • Product Type: Top-End Gasket Kit
  • Engine: Polaris 250cc two-stroke
  • Model Years: 2000–2006
  • Condition: New aftermarket

Installation & Fitment

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.

Frequently Asked Questions

Q: Why must I verify bore size? A: Polaris 250 gasket kits are sold for different finished bores; the gasket opening must suit the actual cylinder.

Q: Can a base-gasket leak cause a lean condition? A: Yes. An air leak can raise temperature and damage a two-stroke piston.

Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.

Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
