Idler Pulley Upgrade for the Porsche® 968

The Problem: Many 968 owners complain of belt slippage on their AC compressor and alternator. The solution (until now) has to been to over-tighten the belt tensioner to compensate, often cracking, bending or breaking the belt tensioner ends under the high loads.

The Solution: The 928 Motorsports LLC® Idler Pulley Upgrade will increase the belt wrap on both the alternator and the air conditioner, so belt slippage is eliminated, and belt tension does not have to be adjusted as high as before. This saves the belt tensioner from breakage also.

Easy Installation: Installs in minutes without any modifications to the vehicle. Pictorial instructions provided.

Warranty: You gotta like it or your money back! If, after you receive this item (but before you use it) you aren't satisfied with it in any way, simply return it for a complete refund.

Shipping: $12.50 in S&H for the 48 contiguous states and will be shipped UPS insured. Additional shipping fees apply for International, email us your COMPLETE shipping address and we will get you a quote.
