Step back in time to any engine shop worth its salt circa 1970 and you’d likely find a number of neat (and now vintage) tools that were staples of mid-century mechanics. A Sun Performance Analyzer might be parked in the corner, a RemLine roll-around tool box perusing the oil-stained concrete floor, and a Rimac spring tester perched atop a workbench, waiting for duty.

While RemLine and Sun have gone the way of the points ignition system, Rimac is back with all-new spring testers soon to be shipping from Specialty Auto Parts USA. With a history that dates back to 1929, Rimac’s product niche has sustained through a history of both quality and performance.

For some time, the only way to get your hands on one was via auction, but prices regularly reached the $1,000 mark for used examples. Like the Sun Analyzer, that problem is soon to be a thing of the past.

Two models will be available: one is for 0-500 lbs. ratings in 2-lb increments (P/N BB0500) and the other is for 0-1,000 lbs. in 5-lb increments (P/N BB1000).

The design revolves around precision and speed with a lever-activated compression mechanism that makes pull-down a breeze. A cast-aluminum C-frame body is heavy-duty enough for high load, yet lightweight for portability. Rimac’s signature blue is powder coated on for durability.
