The days of slipping belts is a thing of the past with the addition of the DMS belt wrap combo. This combo moves the belt +5mm closer to the upper pulley to aid in belt wrap for those running an aggressive pulley setup or an extra small upper pulley. Both components are cnc machined from 6061 aluminum and anodized black. The pulley is assembled with Italian made high speed bearings and a Spirolox retainer ring to maintain proper balance at high speed. Both are designed to reuse OEM bolts to make the installation a breeze.
Note: A belt fitment guide is still being put together. We suggest starting with one size up from your current belt.
Idler Pulley Install Guide
I don't have a ton of miles on the setup but I have 0 concerns. Ran it on the engine dyno with their 76mm idler and a 2.55/9.17 and had 0 issues. Extremely smooth. Highly recommend!
Fit and finish are excellent, belt wrap is increased and is a great looking replacement for my rusty stock upper idler.
