Connecting Rod Balancer Stand / Jig Black
Balance Your Rotating Assembly to Within a Gram — Without the Machine Shop Price Tag.
Vibration kills power. If your connecting rods aren't matched by weight, your high-performance engine is leaving horsepower on the table — and shaking itself apart while doing it. This precision balancer stand lets you weigh big and small ends accurately, create bob weight sheets, and dial in your assembly at home. The same results as a $300 aluminium jig, built to last, for a fraction of the cost.
Accurately balance connecting rods and build bobweight sheets with this durable balancing stand.
Designed for engine builders and performance enthusiasts, this jig helps you precisely measure the big end and small end of your connecting rods for a smoother, better-matched rotating assembly.
Ideal for 4-cylinder, 6-cylinder, and 8-cylinder builds, it can be used for rod balancing, piston and rod matching, and crankshaft bobweight calculations. A practical tool for reducing vibration and improving consistency in high-performance engine setups.
Key Features & Your Benefits:
Precision Where It Counts: Accurately weigh the big end and small end of each connecting rod to match them within a gram. Essential for high-performance, high-RPM engines where imbalance equals rapid wear and lost power.
Create Bob Weight Sheets at Home: Calculate exact bob weights for crankshaft balancing, or simply match piston and rod assemblies before installation. No more guesswork — just numbers you can trust.
Anti-Bind Bearing Design: Bearings integrated into both the swing arm and rod holder minimise friction and binding, delivering more consistent, repeatable measurements across all your rods.
Wide Rod Compatibility: Handles connecting rods with housing bores from as small as 1.800 inches up to 2.500 inches. A dedicated small-end round piece with bearing is included for wrist pins larger than .940 inch. For smaller wrist pins, simply bottom out the screw and use the round piece on the screw end for small-end weighing.
Built from ABS — Not PLA: This is critical. ABS withstands workshop conditions far better than PLA.
Higher heat resistance — won't warp or soften in a hot garage or near a running engine.
Superior impact strength — handles accidental knocks without cracking.
Better dimensional stability — holds calibration longer, giving you consistent accuracy over repeated use.
Quality Checked Before Shipping: Every printed set is inspected before dispatch to ensure your jig arrives straight, true, and ready to use out of the box.
