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

The Big Bore High Performance Front Shocks for Losi® Micro-B™ and Micro-T™ from UpGrade RC are designed to significantly enhance suspension performance and vehicle control.

About the Big Bore Shocks


Unmatched Damping Control

These Big Bore front 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.

Im not sure what star rating to give these yet. Firstly they dont come with oil, so when if you order them you will need to open them up and fill and bleed them. thats no problem, just a little FYI. However, for the life of me I cannot get these things to not infiltrate with air. in my most recent attempt i let them sit for over a day, very carefully assembled everything under bright lights and did it slowly to try and make sure they would be smooth and with no air but every damn time i assemble these damn little things the shocks are crunchy and make noise when they compress, then are just absolutely filled with air bubbles when i take the top off. its getting extremely frustrating. i want to use these shocks with my bug body cuz they look great but im tempted to switch to the losi threaded shocks and just be done with it. If i can figure these things out ill revise my review.
