Custom Ball Specification Requests

When purchasing your bowling ball here at BowlersMart.com, we’re happy to try and accommodate specific requests you may have including pin placement, top weight and gross weight. Our expert team understands that precise specifications can make a significant difference in your ball performance.

Our Specification Tolerances

When making your request, please be advised that our ball spec tolerances are as follows:

Tolerance: +/- 0.5 inches

Example: If you request a 3″ pin placement, we will send a ball with pin placement between 2.5″ to 3.5″.

Why it matters: Pin placement affects how the ball reacts when it encounters the pins and influences the ball’s overall motion down the lane.

Tolerance: +/- 0.5 ounces

Example: If you request 3 oz top weight, we will send a ball with top weight between 2.5 oz to 3.5 oz.

Why it matters: Top weight affects the ball’s initial motion and can influence how much the ball hooks down the lane.

Tolerance: +/- 3 ounces

Example: If you request a 14 lbs 3 oz ball, we will send a ball weighing between 14 lbs 0 oz to 14 lbs 6 oz.

Why it matters: Consistent ball weight is important for maintaining your timing and release consistency.

Best Practice: If you wish for pin or top weight to be within a specific range (example: 2-3″ pin), request the halfway point of that range (example: 2.5″ pin if you require a 2-3″ pin).

Why this works: Requesting the midpoint gives us the best chance to deliver a ball that meets your requirements within our tolerance ranges.

Important Limitation: We cannot guarantee any requests made for mass bias (MB) placement.

Reason: Mass bias placement is determined during the manufacturing process and cannot be controlled during ball selection.
