You need to determine the weight of the front end of the vehicle. The most accurate way is to weight the front half of the vehicle and select the spring rate that works with the front weight of the vehicle.

Do you have any idea on what the weight of your truck might be in the front ? What type of front suspension does the truck have? Is it a straight axle and how is it located or is it a mustang II IFS. I can give you a rough estimate but it would really help to have more information on your application. It might be best to call our tech line so we can ask a few more questions and we can get you a pretty close spring rate. If you have any further questions call me at Speedway Motors (800)979-0122 ext 6235 or at Sales@SpeedwayMotors.com

Yes there is an advantage to mounting the shocks at an angle. The advantage is that they will stabilize the rear of the car laterally. We suggest that they be mounted at 15 to 20 degrees. Adjustable shocks provide the best ride and handling in street rodding!

In choosing a coil over kit for a particular application and especially during the build process try and use the longest shock possible so it will offer the longest stroke to prevent bottoming out or topping out the shock during suspension travel. Also the longer the shock and spring the lighter the spring rate to handle the same vehicle weight. Try and keep the shock angle less than 20 degrees to avoid loosing the efficiency of the shock and spring. Shocks have suggested mount length which is leaving 50-60 percent of the stroke for compression during suspension travel. If the spring is sized correctly the adjuster ring should be ¼ to 1/3 the way up the threads to achieve mount length at ride height with the weight on the vehicle. There is NOT a book or listing for all the vehicles, options, chassis, etc. available and a little homework and conference time with a tech would be a start in ordering the right length and spring rate.
