Rod Ruler

The Rod Ruler suspension tube ruler from Coleman Racing Products is a specialized alignment and measurement tool designed for chassis builders, suspension fabricators, and motorsports mechanics who need precision accuracy when installing or adjusting rod ends and suspension components. This aluminum-construction ruler kit addresses a critical gap in suspension setup: accurately measuring and verifying the positioning of rod end adapters ranging from 5/16 to 3/4 inch specifications without guesswork or costly measurement errors.

Built from lightweight yet rigid aluminum, the Rod Ruler delivers consistent measurement across the full range of common rod end adapter sizes, eliminating the need for multiple calipers or improvised measurement methods. The natural aluminum finish resists corrosion in the shop environment while the streamlined 41.2-inch length provides reach for measuring control arms, tie rods, and upper/lower suspension tubes without obstruction. This kit format ensures you have all necessary adapters for 5/16, 3/8, 1/2, 5/8, and 3/4 inch rod ends, making it a complete solution that eliminates repeat purchases or borrowed tools.

Professional fabricators, race teams, and independent mechanics benefit most from the Rod Ruler when building custom suspension systems, replacing worn rod ends, or verifying geometry after frame repair. The 3.6-pound weight makes it portable enough for mobile service calls or track-side adjustments, while the precise adapter set ensures compatibility with modern suspension components used in street rods, race cars, and performance vehicles. Whether you're performing a complete suspension overhaul or making critical alignment adjustments, this ruler eliminates guesswork and delivers the precision measurement required for suspension integrity.
