Big Bore Performance for Micro-B™ & Micro-T™

The Big Bore High Performance Rear Shocks for Losi® Micro-B™ and Micro-T™ from UpGrade RC are designed to significantly enhance suspension performance and vehicle control. Built for drivers who want smoother handling and improved consistency, these shocks deliver premium performance in a compact package. Featuring the largest bore size available for these platforms, they provide superior damping and impact absorption. Engineered in the USA, they are a high-quality upgrade you can count on.

About the Big Bore Shocks


Unmatched Damping Control

These Big Bore rear shocks feature an oversized shock body that allows increased oil flow for smoother, more consistent damping. The high oil volume helps reduce fade during extended runs, keeping suspension performance predictable and controlled. This results in improved stability and confidence across a wide range of driving conditions.

Plush, Controlled Landings

Designed with balanced compression and rebound characteristics, these shocks absorb impacts more effectively during jumps and hard landings. The suspension remains composed over uneven terrain, helping maintain traction and chassis balance. This improved control translates into smoother driving and reduced chassis slap.

Engineered for Durability and Performance

Precision engineered in the USA, these shocks are built using premium materials and tight manufacturing tolerances. The robust big bore design is made to withstand repeated impacts while maintaining smooth operation. This combination of strength and performance ensures long-lasting reliability for demanding RC use.

I have tried all of them including the new Pro-Line shocks and these are hands down the best option for the Micro B & T.

What reviewers say

Three reviews, two of them rating the shocks 5/5 and one rating them 1/5. The two positive reviewers say the shocks did not leak and describe them as the best option for the Losi Micro-B and Micro-T, one comparing them favourably with Pro-Line shocks. The negative reviewer reports leaking after filling, which they attribute to a possible dent in the shock shaft. Reviewers agree on the shocks' suitability for these models, but the leak report is a single account, and the sample is small.

  • + No leaks reported
  • + Considered best option for Micro-B and Micro-T
  • + Favourably compared with Pro-Line shocks
  • − Leaking after filling reported by one reviewer
  • − Possible dent in shock shaft suspected
