1973-1987 C10 Coilover Kit Installation

RideTech recently installed one of the first of our 1973-87 C10 coilover suspension kits on our shop truck. Check out the video above to see the full installation process. Johnny Merder and John Johnson completed the install over the course of two days in Merder’s home garage with tools you likely already have in your own garage as well. The FAQ below should answer many of the questions you may have or click HERE for the product page.

FREQUENTLY ASKED QUESTIONS
Do I need to remove the bed?
Yes, you will need to drill C notch mounting hole in the top of the OEM framerail. 15 minutes, four bolts and three extra buddies is typically all it takes!
Do I need to remove the cab?
Absolutely no need to remove the cab or even loosen it.
Do I have to use the c-notch?
Yes, our c-notch allows proper ride height, suspension travel, and also
contains mounting locations for the coilovers, panhard bar,
and other suspension components.
Do I have to use the drop spindles?
Yes, we have designed this system to use the included drop spindles to maintain proper ride height, suspension geometry, and suspension travel.
Will my stock brakes work?
This system is compatible with the OEM brake system that uses the 1.250” thick rotor, or any aftermarket system that replaces that system. The OEM system that uses a 1.00” thick rotor is not directly compatible.
How wide of a tire can I fit with this kit?
Safe fitment – Front = 255/40-18
Rear = 275/40-18
Brave fitment =  careful measurements will be required
Do I have to cut my front inner fenders?
Unless you are running some extraordinary wheel/tire fitment that we have not encountered, no inner fender trimming necessary.
Do I have to cut my bed floor?
We have designed this system to be compatible with the OEM bed floor, but there will be two small sections of bed brace trimming necessary (one on each side). Dimensions and instructions are included with the installation guide.
How much horsepower can the kit handle?
We have not found any limitation to horsepower.
Will my existing sway bars work?
The improved sway bar mounting design does not allow the use of the OEM bars, which are so small that they are irrelevant anyway.  We have included a much larger diameter bar that is calibrated to work with the spring rates and shock valving range included with your system.
Can I use my existing exhaust?
Since there are so many variations on exhaust configuration for these trucks (both OEM and aftermarket) it is very likely you will need to modify the tailpipes of you current exhaust.
Can I still tow/haul with this kit?
Yes, up to the original GVW of the truck.
How much will it lower my truck?
We give you a specific fender height measurement instead of a “drop” amount because we never know if you are starting with new springs, old springs, or replacement springs. By going right to the end result [which is the new fender height] we eliminate all those variables for you.  Also, you will have a small window about 1” up or down of available height adjustment.
Front fender height = 25.5” with a 255/40-18 tire
Rear fender height = 24.75” with a 275/40-18 tire
Will it work with a rack and pinion steering conversion?
We have determined that most rack and pinion kits suffer from bracket flex, rack flex, poor steering geometry, and reduced turning radius. The system from No Limit Engineering seems to resolve most of these issues, but we have not yet specifically validated it on this vehicle. For most people a good steering box seems to be the best answer.
