Belt Tensioner with Steel Idler Pulleys

If you have the original belt tensioner from the JRSC kit then you need to change over to the TDR Belt Tensioner Bracket. This innovative product makes tightening the supercharger belt a snap. And TDR has taken the Belt Tensioner Bracket one step further by adding steel idler pulleys modified to keep the belt inline. These pulleys are virtually indestructible and will not get damaged from belt wear.

Thinking of upgrading your old JR M45 or MP62 4-rib supercharger belt tensioner? A new drive belt stretches and requires 2-3 adjustment before reaching the near the longest stretch. The older style JR tensioner bracket requires several bolts to loosen in order to make a simple tensioning adjustment. The new Moss tensioner is a nice improvement over the old style, but lacks in tensioning travel, maximum of 1” and is not as solidly mounted as the TDR Tensioner using two piece design. Plastic pulleys grove over time and their extended sides can make installing new belts difficult.

The TDR Tensioner is made from 1/2” aluminum for solid strength, no flexing. The pulley tensioner adjustment offers over 2” of travel giving you plenty of room to install your drive belt and to adjust proper tension. Steel pulleys provide a much better surface that is easy on the drive belts prolonging belt life. Drive belt tensioning is simple, just loosen the tensioner pulley and adjust the tensioner bolt. The TDR tensioner is for power steering SC setups only.
