Overview
Get pro-grade damping for your 1/10 off-road build with the Hot Racing 100mm Aluminum Heavy Duty Big Bore Threaded Shocks. CNC-machined from billet aluminum with a big bore threaded body, this set delivers smoother damping, more consistent rebound, and a massive durability upgrade over stock plastic-bodied shocks.
Designed as a direct replacement for Traxxas Big Bore EX Long Shocks (TRA2661, 3762, 3762A, 2662) and a versatile fit on most 1/10 off-road platforms using 100mm shocks. Threaded collars allow precise ride-height and preload adjustment, while heavy-duty 3.5mm steel shafts and dual-rate springs handle aggressive bashing without breaking a sweat.
Key Features

Performance Benefits
- Smoother, more consistent damping than stock shocks
- Big bore design improves oil flow consistency
- Precise ride-height adjustment via threaded collars
- Major durability upgrade over plastic stock shocks
Usage Notes
Requires silicone shock oil and proper bleeding. Compatible with any vehicle running 100mm shocks (mounting hardware included). Compatible with optional Hot Racing springs SLF63FS261, SLF63MR268, and SLF63RS286. Bleeding tip: if shaft pushes out more than 6mm or won't push fully in, there's too much oil — loosen the cap a half turn and pump out excess. After final bleed, the shaft should sit about 3-4mm extended with the cap fully tightened.
