Hi Matty

In answer to your question,the 370-0018 (S&S part number) kit consists of the following parts;

1. Pinion pulley hardware update
a. Pinion pulley bolt wasn’t maintaining clamp load. Bolt and washer redesigned and new hardware being used
2. Cam pulley hardware update
a. Pulley retention nuts were working loose and allowing pulleys to wobble. Upgraded hardware now used
3. Tensioner pulley update
a. The pulley was walking off of the bearing. Snap rings incorporated to prevent this from happening
4. Idler pulley update
a. The pulley was walking off of the bearing. Snap rings incorporated to prevent this from happening
5. Cam chest cover spacer kit
a. Provides additional cooling contributing to a greater life expectancy for the cam belt.
b. New cars are built with a vented cover and don’t require the use of the spacer kit
6. Cam belt

Our retail price last year was £356.40 + vat / after negotiations with S&S we we're able to reduce this price to £251.12 +vat.
When you consider the cambelt alone retails at £129.10 + vat, i think you'll agree this is a reasonably / sensitively priced kit.
