Double Adjustable Rear Multi-Leaf Viking Shocks --sold as a pair ------- Part # VB227

Viking shocks for the rear of 1967-1969 Camaro multi-leaf spring cars have adjustable dampening via knobs on the base of the shock. One (on the left) is for bump and the other is for rebound.

Bump occurs when the tire goes up into the fender, rebound is when the tire drops out of the fender. Bump will directly affect the ride so when you are using a stiffer spring in the rear, to much bump can cause a choppy ride. The shock allows you to fine tune your ride as well as tune for performance.

Depending on the spring rate you are using and the type of driving you are going to do, the shock adjustments are going to change.

For a good starting place, if you are using Global West L-2 performance leafs, set the bump to 3 clicks from full soft and the rebound to 7 clicks. This is a good street setting. Performance driving will change these settings, but if you are looking for a good starting point this is it. Global West springs part number L-16 are more of a cruising spring and will require a little more bump and rebound. We suggest setting the bump to 6 clicks and rebound to 8 clicks as a start.

Drag Racing Applications:

Double adjustable shocks will provide you a way to improve your 60 foot simply by adjusting the dampening between bump and rebound. Depending on the type of suspension you are using, 4 link, traction bar, three link, ladder bar or something else. Shocks will be the most important part of the rear suspension.

Depending on where the shocks are mounted will determine how they are going to be adjusted but the ability to separate bump and rebound is important.

For example, if the car does not plant the tire of the line, you could have a number of conditions that can cause this. By having a double adjustable shock on the rear, you can adjust the shock softer and see if the traction changes. Whether to change bump or rebound depends on the type of suspension being used and if the shock is before or behind the axle.

If the tire can not keep up with the load transfer, the rear must be softened so the tire can keep up with the load. If the shock adjustment has no affect, the rear suspension is set to stiff. Because you have an adjustable shock, you can quickly figure out the problem.

Note: Every car is setup differently and some drag cars leave on the tire alone. Dampening is still a issue even for those cars.
