Overview
Bring race-grade damping to your 1/10 off-road build with the Hot Racing 90mm Aluminum Heavy Duty Big Bore Shocks. CNC-machined from 6061-T6 aluminum and built with a 'big bore' threaded body, these shocks deliver smoother damping, more consistent rebound, and a substantial durability upgrade over stock plastic-bodied shocks. The threaded design also makes ride-height and pre-load adjustment quick and precise.
Designed to fit dozens of 1/10 off-road platforms that use 90mm shocks — including Traxxas Bandit, Nitro Rustler/Slash/Sport/Stampede, Rustler, Slash 2WD, Slash 4x4, Stampede 2WD, and Stampede 4x4 (front position) — these shocks are one of the most versatile suspension upgrades on the market.
Key Features
- CNC-machined 6061-T6 billet aluminum bodies, collars, caps, and spring retainers
- Big bore threaded shock bodies
- CNC-machined 11mm Delrin pistons
- 3.5mm stainless steel shock shafts
- Silver and blue anodized aluminum components
- Vented shock caps with bladder seals for consistent rebound damping
- Threaded shock collars with O-rings to prevent unwanted movement
- Composite plastic lower shock ends with aluminum balls
- Fully assembled — just add shock oil and bleed
Performance Benefits
- Smoother, more consistent damping than stock shocks
- Better small-bump compliance and big-hit control
- Precise ride-height and pre-load adjustment via threaded collars
- Massive durability upgrade over plastic stock bodies
- Big bore design provides more consistent oil flow at high shaft speeds
Usage Notes
Requires silicone shock oil (modeler's choice) and proper bladder bleeding. Use shock o-ring grease (such as Team Associated Green Slime) when rebuilding lower seals. Snap ring pliers required for lower-seal rebuild. Use included spacers as needed for installation. Compatible with optional Hot Racing springs HRASLF48FS261 (progressive), HRASLF48MR268 (linear), and HRASLF48RS286 (progressive). Replacement parts: HRARTDS90X (shafts/pistons), HRARTD910BN (ends), HRARTD910RB (pistons/o-rings), HRARTD1010X (bladders/lower seals).
