Losi TLR243005 16mm Shock Pre Load Collars w/O Rings 4 8ight 3.0

The Losi TLR243005 is a set of 16mm shock pre-load collars with o-rings, sold as a pack of 4, built for the 8IGHT 3.0. Pre-load collars sit on the shock body and let you adjust spring pre-load, changing ride height and initial suspension stiffness without swapping to a different spring rate entirely.

This is one of the simplest and most effective tuning adjustments available on a shock, letting you fine-tune your 8IGHT 3.0's stance and initial suspension response for different track conditions or personal preference. The included o-rings create a seal against the collar, helping keep the threads clean and the adjustment moving smoothly rather than binding up with dirt over time. Worn or missing collars can leave your pre-load setting inconsistent from corner to corner, so keeping fresh collars on hand helps maintain accurate, repeatable adjustments. This genuine Losi set matches the factory 16mm shock body diameter, installing directly onto your existing shocks.
