Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

It is a well-known issue on the BMW N54/55 platforms that your serpentine belt can fail for various reasons. When this happens, there is a high chance of the belt getting sucked behind the front damper pulley and then being pushed past the crank seal into your oil pan. From there it can get sucked into the oil pick up causing total engine failure. Even if you do not lose the engine, it is a COSTLY repair to remove the sub-frame and drop the oil pan to remove the belt. The best way to combat this is to watch for oil leaks and keep up on your maintenance. BUT, even with those preventative measures, pre-mature belt failure can occur. This crank seal guard installs over your front crank seal and will keep the belt from being sucked in if a belt failure does occur. This is a cheap way to ensure you do not end up having to replace your motor from oil starvation due to an ingested belt. Vargas' seal is different from those already on market in two major ways. Firstly, it is not offensively priced. Secondly, it is 100% billet with no welds on the tabs to break, no cheap bent thin steel pieces. 100% Billet 6061-T6 aluminum, anodized black for long-term corrosion resistance. Crank Seal Guard includes: One VTT Billet N54/55 Crank Seal Guard Two extended 12.9 Grade bolts, and two stainless washers We highly recommend you install WITH a crank bolt capture at the same time, as you have to remove the damper anyway. Then you will get the benefit of helping eliminate the dreaded spun crank hub and the crank seal issue

This is a Genuine BMW Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

Vargas has introduced their new Billet Power Steering pulleys for the N54 engine! A well-known issue with the N54 with Hydraulic power steering is the plastic pulley either hitting the subframe, or breaking on its own. This can result in the belt to be ejected from the pulley, and leave you stranded with no serpentine belt. This also increases the chance of sucking the belt into the engine through the front seal. Put an end to the dreaded plastic PS pulley issues with the VTT 100% Billet Aluminum PS pulley. These are constructed from 6061-T6 aluminum and anodize in one of 4 colors (Black, Red, Blue, and Clear) for a great look, and long-lasting finish. These weigh 11oz, very close to the weight of a stock pulley, and are lighter than the cast aluminum versions on the market.

Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping. Replace your belts and tensioners on a regular basis to ensure you don't end up stranded on the side of the road with a dead battery or over heated engine due to a bit of simple overlooked maintenance.

This is a Genuine BMW Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

This kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually. This kit includes an updated hydraulic alternator tensioner for added reliability and longevity.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes ECS Kevlar Reinforced Drive Belts, tensioner assembly, and idler pulleys. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!
