HPI Bullet 3.0 MT/ST Suspension Upgrade Adjustable Dampers BMT3100F/R by GPM  [BMT3100F/R]

Front and rear adjustable shocks tailored to Bullet 3.0

The BMT3100F/R is an aluminium alloy front and rear adjustable spring damper set intended for HPI Bullet 3.0 MT and ST nitro chassis. Delivered as a single pair, the dampers use a 3.5mm steel shaft mated to an aluminium body to improve durability over typical plastic housings while keeping weight appropriate for model suspension.

These dampers give adjustable spring support so you can tune ride height and spring preload at each corner. The hardware matches the Bullet 3.0 MT and ST mounting layout and stroke, enabling direct swap-in of aftermarket shocks without altering chassis mounting points.

During setup focus on spring rate and preload changes before swapping pistons or oil; the alloy body and sturdy shaft are aimed at strength and straight shafts, while oil grade and piston choice remain the main way to adjust damping characteristics. Use common RC tools, confirm correct thread engagement and pivot operation, and ensure smooth shaft travel before running.

A practical metal-bodied shock set for hobbyists who want a thicker shaft and improved durability on HPI Bullet 3.0 MT/ST nitro machines without complex modifications.
