Rancho Suspension introduces a high-performance off-road suspension system for the '97-'98 Ford Expedition 4x4. It's designed to provide a more aggressive stance by increasing the vehicle's ride height 4 inches. The system can fit 33-inch tires without modification to the fenders, depending on wheel width and offset. Information: To find your nearest retailer, call 888/GO-RANCHO (467-2624), www.gorancho.com.
Chevy Battery Tray
You can replace the corroded battery tray in your '67-'72 Chevy or GMC truck with a reproduction unit from Harmon's Chevrolet Parts.

Automatic Transmission Coolers
The SuperCooler automatic transmission cooler from B&M is small, lightweight, and said to still deliver the same cooling as an ordinary fin-and-tube cooler, if not better. Its low pressure-drop feature reduces the risk of lube system failure. All kits are pressure tested up to 200 psi and come with cooler lines as well as fitting and mounting hardware. Information: B&M Racing and Performance Products, Dept. 4WOR, 9142 Independence Ave., Chatsworth, CA 91311, 818/882-6422.
The Vari-Curve from MSD lets you select the rpm at which you want your timing curve to begin and end, along with the amount of retard or advance. This is all possible with an easily adjustable plug-in module. You can even use an MSD two-step module selector to provide two different amounts of timing. The company says the Vari-Curve is easy to install with your MSD ignition and simple to adjust without programs or codes to memorize.
