The Metco Motorsports auxiliary idler kit for the Lightning is cleverly engineered to be a simple bolt on and to be the ultimate solution to belt slippage.

The kit consists of a heavy-duty, precision-machined aluminum plate that offers an optimized location for the included black hardcoat-anodized 90mm idler pulley.  The plate bolts to existing bolt locations on the vehicle and locates the pulley just to the right of the supercharger pulley, maximizing belt wrap and eliminating slippage.  The necessary fasteners are included, including steel stand-offs precision-machined from high-grade steel as well as a billet bearing cover for the pulley. Illustrated installation instructions are provided.

This product is an original Metco Motorsports design that has been copied a number of times, but none of the copies match the quality and precision fit of the original.

This kit is compatible with both Eaton and Kenne-Bell superchargers, and is also available with a larger 100mm idler pulley (MLI-100, also listed in this section) for use with overdrive (smaller) supercharger pulleys.  Both 90mm and 100mm kits are available with a double-bearing idler pulley upgrade.

The VMP 90mm idler pulley uses a factory size and brand NSK heavy-duty bearing, when the proper sized bearing is used the need for double bearings is eliminated.
Use this idler to take up belt slack and get better wrap with smaller supercharger pulleys. Can be used with 2.4"", 2.5"", 2.6"", 2.7"" or 2.8"" super charger pulleys on a 07-12 Shelby GT500.
Can be used on the 11+ 5.0L Mustang Gt with the Roush, Whipple and VMP Superchargers. (Some filing may be needed due to core shift in the bracket for the idlers.)
Also used with Roush M90 and P51 TVS blowers when installing a smaller SC pulley, install below the supercharger pulley.
Will fit other applications that require a idler with 17mm bore. Factory bolt is re-used.
On a GT500 the idler pulley should be installed below the intercooler tubes, to the left side of the blower.

These billet idler pulleys are custom-sized at 100mm (3.9”). This specific diameter is a benefit in supercharged applications, such as in the auxiliary idler position where the additional belt wrap at the supercharger pulley serves to reduce belt slippage. The larger diameter of this pulley serves to improve belt wrap in any position on the engine, results in slower speeds at the pulley bearing, which adds to longevity and reliability, and most prefer the appearance of the larger face of the pulley. In applications such as the Mustang Cobra or Lightning truck, these 100mm idler pulleys can often be installed as direct replacements for the original 90mm idler pulleys. Please note that the Mustang Cobra requires at least one 90mm idler in the center position of the blower drive to maintain proper belt clearance.

Like all Metco idler pulleys, these pulleys are CNC-machined from certified 6061 billet aluminum. We machine the bearing bore and the belt surface as part of the same machining operation on our CNC lathe to eliminate the possibility of pulley runout or wobble. An application-specific hardcoat anodizing is applied to the belt surface, bearing bore, and backside of the pulley to maximize strength, resist corrosion, and minimize belt noise. High-speed, high-load bearings with large steel rollers, heavy grease, and double grease seals are precision-fit into the center bore, and a snap-ring ensures everything stays in place.

Following machining, plating, and assembly, each pulley is spun on a fixture to ensure that it meets our high standards prior to packaging. Each pulley ships with the billet bearing cover and high-quality stainless steel fasteners, as shown.

These 100mm idler pulleys are offered in two configurations. The 8-rib (1.5” wide) single-bearing version is intended for use on the supercharger drive of the Mustang Cobra, Lightning truck and Harley Davidson F150 applications. These single-bearing pulleys are our most popular, and in a properly set up system, should be expected to be a permanent solution to the problem of failure-prone OEM idler pulleys. The 10-rib version of our 100mm idler pulley is a double-bearing pulley, fitted with two of the heavy-duty bearings, which serves to spread the load from the supercharger belt over twice as much surface area. This design adds a significant amount of load capacity, and is recommended for use in severe applications, such as those running very high belt loads and boost levels, or where the supercharger belt is tighter than recommended. Note that the 10-rib pulleys are 1.75” wide at the belt surface, and while these pulleys fit perfectly in the Cobra and Lightning applications, these pulleys are wider than the original pulleys.

Important note: When an existing 90mm pulley is replaced with a larger 100mm pulley, 0.5” must be added to the required belt length. In the case of the Mustang Cobra, where there are often (3) 100mm idlers used on the blower drive, a total of 1.5” should be added to the calculated belt length.

divisionX 100mm Dual Ball Bearing Idler (Clear)

The new idlers from divisionX are not only the best looking idler to hit the market place but were also designed to be the best performing idlers as well. The design was inspired from the 2010 GT500 wheel which looks amazing. divisionX idlers are cnc machined out of high grade billet aluminum which ends up getting hard anodized for a long lasting protective finish. It uses not one but two heavy duty ball bearings which are meant to outlast the single bearing design as well as stand up to the abuse that these idlers see from being spun at such high rpms. All of the idlers also come with a cnc machined dust cover which helps provide support for the idler and keep dust and debris out of the bearings. 

These idlers not only work with their idler bracket but also can be used as a heavy-duty replacement for the two idler pulleys on the factory crossover bracket, and as a heavy-duty replacement for the factory crank idler on the 2003-2004 Mustang Cobra.

Features:

CNC Machined High Grade Billet Aluminum

Hard Anodized for a long lasting protective finish

Heavy Duty Dual Ball Bearing Design

Billet Dust Cover provides extra support and keeps dust and debris out of the bearings
