A blown seal is one of the most common and most destructive shock problems riders face. Once a seal fails, oil leaks out, nitrogen pressure drops, and your shock stops doing its job. At T2 Shock Garage, our seal replacement service restores your shock’s ability to hold pressure, stay lubricated, and perform safely at every speed. If you see oil on your shock body, dust cap, or floor, your seal is done and it’s time for replacement.

A worn or blown seal causes:

• Oil leaks
• Nitrogen loss
• Inconsistent dampening
• Harsh or unpredictable suspension
• Rapid internal wear
• Shock fade
• Increased risk of catastrophic shock failure

In Southern California, where heat, sand, and dust are brutal on suspension, seals wear out fast. Replacing them early saves the shock, the shaft, and your wallet.

At T2 Shock Garage, we don’t just slap in a new seal and hope for the best. Every seal replacement includes:

• Full shock inspection

• Removal of old seals

• Installation of high-quality replacement seals

• Cleaning of the shock body and shaft

• Check for shaft scoring (rehoning recommended if needed)

• Fresh shock oil if required

• Nitrogen recharge (if pressure loss is detected)

If the seal failed because the shaft is scratched or damaged, we’ll catch it and fix it.

Common causes:

• Heat cycling in Coachella Valley desert conditions
• Sand abrasion
• Shaft scratches or pitting
• Old or contaminated shock oil
• Worn bushings or misalignment
• Riding with low nitrogen pressure
• Long intervals between rebuilds

Your seal is the barrier that keeps the oil where it should be. When it goes, the shock can’t do anything correctly.
