Why Choose the TruRyde® Defender Oil Cap?

• 360-Degree Seal — All sealing elements are on the inside, not the outside. No gaps. No exposed hardware. Nothing for day-to-day abuse to compromise.
• Fewer Failure Points — Other caps have as many as 13 individual components. The TruRyde® Defender does the job with fewer parts, which means fewer ways for things to go wrong.
• Heavy-Duty Die-Cast Aluminum Housing — Significantly more robust than traditional Lexan caps and can stand up to impacts that would crack or shatter a plastic housing.
• Particle-Capturing Magnet — The built-in magnet captures metal particles so they cannot wear down bearings.

The TruRyde® Defender Thread-On Oil Cap is available in both Oil and Grease versions. Choose from bulk packaging or retail-ready two-cap packs complete with labeling and barcode for easy merchandising.
