Shock Duplicator Tool
RPM Shock Duplicator Tool
This is the RPM Shock Duplicator Tool. How do you know if your shocks are built correctly? Do you “eyeball” the rebound of your shocks after rebuilding them? Is that rebound identical to the opposite side shock? How about shock length? Do you have an expensive set of calipers to measure length? Does that set of calipers take into account the clearances in your shock pivot balls? Most likely you’ve never considered any of these things. RPM has and their Shock Duplicator takes the guesswork out of building or rebuilding your shocks.
The RPM Shock Duplicator uses a simple comparison method to determine if your shocks are identical. It’s simple, accurate and most importantly, inexpensive! Simply bolt a pair of shocks to the Duplicator and, following the straightforward instructions included, you’ll take all of the guesswork out of your suspension system. No expensive calipers, no “calibrated eyeballs”, just accurate information at your fingertips. All gauge indicator and scale readings are molded directly into the tool for lifelong accuracy.
Tech Notes: The RPM Shock Duplicator works with most 1/8, 1/10 or 1/16 scale shocks using 4-40 or 3mm mounting screws. Maximum shock length is 6-1/4” (158mm). Shocks not included.
