FS Performance Engineering Splitter Rods are crafted in the USA for splitters and spoilers that need additional front/rear end support. These rods have 1.75" of adjustability and are made from aircraft grade 6061-T6 billet aluminum. Our rods stand out due to their creative design and built-in wrench flats for tightening. They are also offered with polished silver or anodized black barrels. WE ARE MORE THAN HAPPY FOR THE SUPPORT WE'VE BEEN GIVEN SO FAR as our splitter rods are deemed some of the best on the market by the those who have purchased them so far. When mounted correctly they can stand the test of time and strength.
