What are the benefits of the Offroad Design Standard Lift System?
Good ride without breaking the bank
We select great quality products that will give your rig a good ride. We make it so you can select or not select parts. That way you dont have to buy a whole "kit" with things you do not need.
Mix and Match
No generic off the shelf lift here, we let you pick the items that work best for your project!
Through our years of working with these trucks we have selected the products that they can really benefit from!
The Spring of choice for this kit is the Skyjacker Soft ride. They offer a great ride with some good flex. these springs will not work with cummins or duramax swapped trucks.
The options for the rear lift are a set of 52 inch rear springs. You should check to make sure your rear springs are 52" long as we have founds some variations. You can move your stock hangers to accommodate the 52" spring if your rig has a different length.
What are the HD shackles and Greaseable Kevlar Bushings?
Heavy Duty Front Shackle Kit
Our Heavy Duty Front Shackle kit is just that, Heavy Duty! These are great replacements for the flimsy stock shackles that come with these trucks. We add a .5" to the length of the shackle to help with frame clearance (don't worry we account for the length in the build of the springs). The plates are zinc plated gold for long lasting quality We use better than grade 8 bolts with a high head for the grease zerk The sleeves are made from chromoly tubing To "top" it all off we use a top lock nut
Our Kevlar bushings are a high tensile strength bushing that is built to last! They are also soft enough to not hurt the ride. These bushings are designed with grease channels to help flow to all parts of the spring eye
Bilstein Shock Info
Why use Bilstein shocks
Bilstein is a great all-around shock that is extremely durable. We have selected a valving that is an amazing pair with our custom springs and offers good on and off road ride
Do I need the extended shock mounts?
The stock shock mounts are pretty low on the frame limiting travel of the suspension. This results in lower ride quality and not getting full use of your suspension. Using the extended shock mounts ensures that your suspension will not be limited by the shocks. The extended shock mounts are a benefit for both on and off road vehicles. The extended shock mounts are a bolt on application but do require drilling and cutting. More information on this under product attachments at the bottom of the page.
Measuring Spring Length
Throughout the models there were a couple spring lengths for the rear. The best way to know for sure what you have is to measure your springs. The proper way to measure would be bolt to bolt following the arch of the spring. Do not measure straight across. One way of doing this is using a piece of string to follow the contour and then measuring the spring
What banjo bolt do I have?
Our lift systems come with the option of Stainless steel braided brake lines. These lines are DOT approved and pressure tested for leaks. These line will connect directly to your stock hard lines. You will need to select what size banjo bolt fitting you have. As a rule of thumb 1978 and older trucks got 7/16 banjos and 1979 and later got 10mm, to be certain you should measure the threads of your banjo bolt. This can not be determined by what size wrench is on the bolt head. You will need to measure the threads with a caliper like pictured . Make sure to also select the adapters needed to use the brake lines with your rig.
Why Crossover Steering?
Crossover steering is the best way to correct after you lift your truck. It offers full lock to lock turning throughout the whole suspension travel. the short draglink used in stock push/pull steering it is greatly affected by changes in driving surfaces. This creates an unstable feeling in the steering. With the longer draglink that is used in crossover steering you will have a more precise feel. Street driven trucks and off road vehicles a like benefit greatly from crossover steering. More info on crossover can be found here under our crossover steering page
What is needed for crossover steering?
A 2wd steering gearbox is needed for crossover steering and is available on this page. The 2wd steering gearbox is needed because it is fully splined to accept the crossover steering pitman arm. It will bolt onto your truck just like the factory 4wd one.
What is the steering box brace
The frames of these trucks tend to crack behind the steering gear box, especially when more leverage is applied with larger tires. We carry a brace that triangulates that area to help prevent cracks from forming
35s and smaller
No trimming required
Trimming of front and rear of fender opening
38s and larger
Drive Shaft Modification
With lifted vehicles there is always a chance of a longer drive shaft being needed for the front. Typically the rear drive shaft still works but it is worthwhile checking to make sure.
After lifting a vehicle the angle of the drive shaft typically changes. Sometimes the pinion may need to be shimmed to prevent vibration. This cant be checked until after everything has all been installed. We do carry shims to help correct if needed.
What is this kit for?
1967-1972 Trucks/SUVs with a GM Dana 60 Front Axle
This kit will work with 1967-1972 Chevy/GMC Trucks/SUVs
Kingpin GM Dana 60 front axles only
This kit will work with 1967-1972 trucks and SUVs that have a kingpin dana 60 swapped in. This will not work with any of the Dana 44 or corporate 10 bolt front axles.
HD front shackles and main eye bushings
The tough country springs come with poly bushings but if you would like to upgrade to our greaseable kevlar bushings and Heavy Duty shackles we offer that as a kit.
Rear greaseable kevlar bushings and Super Shackles
You can use the stock rear shackle but if you want a stronger upgrade we offer the super shackles. The 4.5" long shackle would be the correct one to use in this kit. The 6" shackle will not work. The 52" rear Skyjacker springs have a 1.5" eye on each end. Our Super shackles use an 1.5" eye.
Steering box brace
It is extremely common for the frames to crack right behind the steering box on these trucks. Adding the box brace helps prevent that from happening
In this generation we have found a wide range of rear spring lengths and mounting widths. They normally do not use the standard 52" long spring that is 3" wide at the mounts. To use this lift kit you will need to move hangers and use spacers to fit the springs on your truck. They will not be a direct bolt in.
Closed Knuckle Front Axle
If you have a closed knuckle front axle any steering correction for the lift will not work. There isn't a conversion kit for this axle, the easiest/cost effective way is to swap in an newer D44 or corporate 10 bolt that is not closed knuckle.
Non power steering trucks
If you have a non power steering truck you will have to convert it to the later power steering box. This box requires indents in the frame for the box to fit. We have a weld on kit part# GU39003.
