Both listed chassis fitments are 50mm in diameter and 1030mm long.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between the OTK and KR versions?\u003c\/h3\u003e\n\u003cp\u003eThey are separate fitments for the two chassis families. Precision does not publish the exact drilling and keyway measurements on the product page, so they should not be treated as universal alternatives to one another.\u003c\/p\u003e\n\n\u003ch3\u003eWhich stiffness should I choose?\u003c\/h3\u003e\n\u003cp\u003eMedium is the sensible baseline in Precision's guide for mixed conditions. Move softer or stiffer to answer a specific handling or grip problem, using your chassis data and controlled back-to-back testing.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my chassis?\u003c\/h3\u003e\n\u003cp\u003eOnly if the selected OTK or KR fitment and the axle layout match your chassis.
