Death Metal Racing lightning bolt valve stem caps. Available in numerous anodized colors and laser engraved. Lightning bolt caps available in short and long versions. CHECK CLEARANCES BEFORE ORDERING! Short valve stems will add .350" to the height of your valve stem and will clear most all bikes,  Long valve stem caps will add 1/2" to the height of your valve stem, and a small number of bikes will have interfereance issues with the caliper. Valve stems normally get changed with each tire change, so your bike could have different length stems than what it came with. IT IS YOUR RESPONSIBILITY TO CHECK. MEASURE FIRST BEFORE ORDERING. WE ARE NOT RESPONSIBLE FOR CLEARANCE ISSUES. Sold in pairs. Made in the USA!
