Using a Proper Shocks for Competition

Add Article To List

When building a car for any type of competition whether it be oval track, autocross, or drag racing, a shock needs to be able to be re-valved. The problem with that is when you need a shock that mounts in the stock location, most stock mounted shocks can't be re-valved as they are sealed. The shocks I picked up for my Laguna, the AFCO/ProShocks Pro TASS Stock Mount Shocks (P/N AUP-3325), are just the ticket.

The awesome thing about the Pro TASS stock mount shock is it's versatility. This shock can not only been re-valved to varying track conditions, but it also has threaded studs on each end. This allows a variety of mounting ends to be installed for any particular applications, from a Laguna to a Nova to a Buick.

After the ends are installed, the Pro TASS stock mount shock looks like any other stock shock, only with so many hidden advantages. AFCO even includes a shock travel indicator, and a snap ring should you choose to add a coil over sleeve to turn this shock into a coil over application.

Since this has the stock mounting capability it looks right at home sitting in the front suspension of my 1976 Chevrolet Laguna S3. My Laguna is being built for the NHRA Pro Bracket Racing Series, so having a shock that can be re-valved to a specific rebound or compression rate is huge. The ability to change the shock ends allows me to be able to carry a variety of shocks for varying track conditions.

The lower shock mount is held in by bolts and nuts, the factory shocks used hex flange screws and J-Nuts for mounting. I chose to use allen button head screws and nylon lock nuts. I decided to leave the front spring out so the lower shock mounting could be seen easier.

Before the upper shock stud is pushed up through the upper shock mounting hole the concave washer is installed and then the upper shock bushing is installed.

Another upper shock mounting bushing is installed, then the concave washer, followed by the retaining nut. The nut is then tightened down tight enough to seat the bushings with a slight bulged to the bushing. Now all that's left is to enjoy the versatility of the Pro TASS stock mount shock from Speedway Motors.
