The key is the unique design of our aluminum pulley mounting bracket. Our heavy-duty bracket is designed so that it will not deflect under heavy belt loads like some other designs, as deflection in the bracket eases tension on the belt and allows the belt to slip. The bracket is machined from a solid 4” x 4” block of certified 6061 billet aluminum. The bracket is configured so that it seats firmly against the OEM crossover bracket for unmatched stability, and it mounts with (2) M8 fasteners in existing locations. Other than the removal of the factory belt guard (remember those?), no modifications are required for installation.

The larger pulley maximizes belt wrap at the supercharger pulley, and this 100mm pulley is compatible with most popular supercharger pulleys sized 3.25” and smaller. For larger supercharger pulleys, the 90mm size would be appropriate to ensure adequate clearance for the belt between the idler and the supercharger pulley. We offer this kit with both single and double-bearing idlers, and these idlers are identical to those we offer for the other (3) idler locations on the Cobra’s supercharger drive. \u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003eThe kit includes the billet bracket, one M8 fastener (one existing M8 fastener is re-used), the idler pulley of your choice, and the appropriate bolt and bearing cover for the pulley.

The key is the unique construction and design of our pulley mounting bracket. The bracket is machined from a 8 x 6 x 2? solid block of certified 6061 billet aluminum, and it is configured so that that it uses two existing and solid mounting points for unmatched stability. The unique design re-positions an existing idler pulley location so that it is positioned very close to the supercharger pulley. This improved pulley location changes the belt path to maximize belt wrap and eliminate belt slippage under heavy belt loads. The bracket is vibratory polished after machining for a smooth finish and long lasting corrosion resistance.\u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003eFor most applications, the larger 100mm idler pulley is appropriate. The larger pulley maximizes wrap at the supercharger pulley, and this 100mm pulley is compatible with most popular supercharger pulleys sized 3.25? and smaller. For larger KB and Whipple supercharger pulleys, the 90mm size would be appropriate to ensure adequate clearance for the belt between the idler and the supercharger pulley. We offer this kit with both single and double-bearing idlers, and these idlers are identical to those we offer for the other idler location on the Lightning supercharger drive. \u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003eThe kit includes the billet bracket, one M8 fastener, and two heavy-duty CNC-machined steel standoffs necessary to properly position the bracket.

The double-bearing pulleys use two bearings in the pulley bore, which serves to spread the load from the belt over twice as much surface area. These pulleys are the most durable pulleys we can manufacture, and are intended for severe applications. Because double-bearing idlers are also used in 10-rib applications, they are wider (1.75? at the belt surface) than OEM pulleys. There are absolutely no fitment issues with double-bearing pulleys in the Lightning application, but a standard 8-rib belt will leave about 0.25? of unused pulley surface at the front of the pulley, as shown in images 4 and 5.\u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003eAll Metco Motorsports products are designed, manufactured, and assembled at our facility in Anderson, SC.\u003c\/p\u003e","brand":"METCO","offers":[{"title":"Default Title","offer_id":61757146038642,"sku":"MLI","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/metco-metco-motorsports-auxilliary-idler-kit-99-04-lightning__60372.1678999411.600.600.jpg?v=1775938757"},{"product_id":"metco-motorsports-custom-crank-pulley-hub-for-ati-balancer-99-04-lightning","title":"Metco Motorsports Custom Crank Pulley Hub for ATI Balancer 99-04 Lightning","description":"\u003cp style=\"font-weight: 400;\"\u003e\u003cstrong\u003eCustom Crank Pulley Hub\u003c\/strong\u003e\u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003e\u003cstrong\u003eFor 1999-2004 Lightning Truck with ATI 918037 Balancer\u003c\/strong\u003e\u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003e \u003c\/p\u003e \u003cp style=\"font-weight: 400;\"\u003eThis specially-machined crank pulley hub is designed for users of our ICP9903 interchangeable crank pulley kit who have equipped their Lightning or Harley-Davidson F150 with an ATI harmonic balancer.

Our proven interference fit makes the troublesome step of pinning the hub to the supercharger shaft unnecessary. \u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003e\u003cstrong\u003eImportant Notes:\u003c\/strong\u003e The unique design of our pulley hub that allows the installation of the stock-appearing front pulley cover will complicate the hub removal process in the unlikely event removal becomes necessary. While a simple fixture can be fabricated to draw the hub off the shaft, it is also an option to cut the hub to release it from the shaft and then replace it upon reassembly.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003eAs a result of production changes made to this part since its introduction in 2009, extra hardware is included with each hub purchased separately to ensure proper thread engagement for the (6) ring fasteners. Ring fasteners must not protrude past the rear flange of the hub when tightened, so extra bolts and washers are provided to ensure maximum thread engagement into the hub without the bolts extending past the hub flange.\u003c\/span\u003e\u003c\/p\u003e","brand":"METCO","offers":[{"title":"Default Title","offer_id":61757147119986,"sku":"LSA-HUB","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/metco-metco-motorsports-supercharger-pulley-hub-for-lsa-and-lt4-applications__69994.1678992799.600.600.jpg?v=1775938799"},{"product_id":"perrin-93-14-subaru-impreza-incl-02-14-wrx-04-21-sti-lightened-crank-pulley-blue","title":"PERRIN 93-14 Subaru Impreza (Incl. 02-14 WRX) \/ 04-21 STI Lightened Crank Pulley - Blue","description":"PERRIN 93-14 Subaru Impreza (Incl. 02-14 WRX) \/ 04-21 STI Lightened Crank Pulley - Blue","brand":"Perrin Performance","offers":[{"title":"Default Title","offer_id":61770444669298,"sku":"PERPSP-ENG-100BL","price":134.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/3c9eedd1a1ac5ce6ac07b001cfc6dc9f.jpg?v=1775962286"}],"url":"https:\/\/hypermotive.com\/collections\/pulleys-crank-underdrive.oembed","provider":"Hypermotive Performance","version":"1.0","type":"link"}
