Jackshaft Sprockets 40/41/420 Chain 3/4 Bore 14T/10T – pinkhatcat

Description

Product Overview

The pinkhatcat Jackshaft Sprockets are purpose‑built for high‑performance 40/41/420 chains commonly used in go‑karts, mini bikes, and other lightweight powersports vehicles. Each sprocket is machined from premium alloy steel that has been heat‑treated to achieve a balance of hardness and toughness, ensuring the teeth retain their shape under aggressive acceleration and deceleration cycles. The 3/4 inch bore provides a precise fit for standard jackshaft shafts, while the 3/16 inch keyway guarantees secure torque transfer without slippage. The dual‑tooth configuration—14 teeth on the primary wheel and 10 teeth on the secondary wheel—optimizes gear ratios for rapid power buildup and smooth power delivery across a wide RPM range. Detailed specifications include a compact package size of 3.03 x 2.68 x 2.09 inches and a lightweight mass of just 10.23 ounces, making the sprockets easy to handle during installation and service. Designed by pinkhatcat, a brand known for reliable powersports components, these sprockets have earned a solid reputation reflected in a 4.4‑star rating from 33 verified customer reviews. The product’s best‑seller rank of #93 in Powersports Sprockets underscores its popularity among enthusiasts seeking a cost‑effective yet high‑quality upgrade.

Usage

These jackshaft sprockets excel in environments where rapid acceleration, precise handling, and durability are paramount. Whether you are racing a go‑kart on a tight indoor circuit, navigating a mini bike through off‑road trails, or customizing a hobby‑grade motorbike for track days, the sprockets provide consistent power transmission that translates into smoother throttle response and improved traction. The 3/4 inch bore aligns perfectly with most standard jackshaft assemblies, allowing for quick swaps without the need for additional adapters or machining. The 3/16 inch keyway ensures that the sprocket remains locked to the shaft even under high torque loads, reducing the risk of gear disengagement during hard launches. Users have reported noticeable gains in acceleration times and a more predictable handling feel after installing these sprockets, making them an ideal choice for both competitive racers and casual riders who demand reliability from their drivetrain components.
