Front Coilover Conversion System for '67-87 ('91) GM Trucks

When you’re ready to move beyond leaf springs, this is the way.  Our link and coilover system lets you enjoy big articulation, 14” of vertical wheel travel AND excellent steering precision and axle wrap control.  We have worked with every type of front suspension and this coilover conversion is the only one that does it all:

Outstanding ride quality over any terrain from gravel roads to rocks, sand, and whoops
Great articulation
Precise steering response under all conditions
No bumpsteer
Total axlewrap control
No approach angle limits
Excellent damping from the King 2.5" reservoir shocks
Easily adjustable spring rates and ride height
Lift heights available from near stock height up to 12"
With the addition of an optional sway bar, our coilover conversion also provides excellent street manners.  The best of both worlds!

Our default kit is based around a 2-1/2" King remote reservoir coilover shock but we do have many options beyond that!
We can do bigger shocks, internal and external bypasses, bumpstops, the sky is the limit! See our shock package options by clicking here.

Coilovers aren't just for hardcore offroad rigs, they work great on the street and even on tow rigs too! We spec out the brackets and shock valving based on your truck and use, so the system is tailored to your specific situation. The coilover ride great (spring rates are a fraction of leaf spring rates), have awesome shocks to control everything, and with no bump steer and a panhard bar keeping the axle located side/side, it's really the ultimate on the road too!

We can even spec coilovers for things like Cummins swaps and with air bags in the back, coilovers work great while towing! Even trucks that just do normal truck things drive, ride and work the best with coilovers!

One of our employee's 12V Cummins swapped pickups with our front and rear coilover systems, it sees use primarily as an all around daily drive, tow rig and general use pickup

*This is the D44/10bolt system on a custom trussed D44*

This is our new high clearance version of our coilover brackets, if ground clearance is a concern we use these on trucks up to 6" of lift.  For taller lifts, we use the original coilover brackets.  This customer had already made his own shock hoops, the ones that come with the kit are at the bottom of this page.

The brackets "jig" themselves onto the axle, there is no work in fitting the brackets to the axle.  Just weld them up!

This customer welded the brackets to his frame, welding is not necessary and the brackets bolt into the holes for the body mount.

Our Coilover Conversion System completely eliminates your truck's front leaf springs and replaces them with a four link suspension sprung and damped by a pair of 2.5" King Coilover shocks.  This kit includes:

2.5" x 14" King remote reservoir coilover shocks with springs and hardware
Axle mount brackets
Frame brackets for link arms and panhard bar
Link arms with Johnny joints for both ends
Heim jointed panhard bar
Shock hoop/engine cage kit
All mounting hardware

Installation requires welding the mounting brackets to the axle and also to attach the panhard bracket to the frame.  Fabrication is required for the upper shock mount/engine cage system.

Cost is $3484 for the complete front coilover conversion including King coilovers shocks

*Our kit also works great with full hydraulic steering as well*

We often get asked about selling these parts individually, so some of them are broken down below:


D60 Axle Brackets

Versions available for GM D60, Dodge D60
and '77-'79 Ford D60

We do not have brackets for the '85+ Ford D60's due to short axle tube on short side

1/4" steel plate construction with 3/16" gussets

Fully welded

Panhard bar, coilover, limit strap and link mounts all incorporated



GM Dana 44 and Corporate 10 Bolt Axle Brackets

Version for early 2-3/4" tube and late 3" tube

1/4" steel plate construction with 3/16" gussets

Fully welded

Panhard bar, coilover, limit strap and link mounts all incorporated

Panhard bar bracket

1/4" steel plate construction with 3/16" dimple died gussets

Fully welded

"High Clearance" style frame side link mounts

1/4" steel plate construction

Fully welded

Keeps the links up higher for better ground clearance

Popular with the rock crawler crowd with low lift heights

Standard frame side link mounts

1/4" steel plate construction

Fully welded

Popular with "go-fast" type rigs, these keep the links nice and flat. Also the most common bracket set for street driven rigs.

"Tall Truck" style frame side link mounts

1/4" steel plate construction

Fully welded

Drops the link down to keep them flat on taller trucks


Shock hoops

Pre-bent and left long to accommodate different ride heights and different arrangements to fit your individual truck.

"Engine cage" tubing is included in the kit and it's left up to you to run it between the shocks hoops.  We did this so that you can put the cross piece in where it clears your intake system etc. and so that it also ties the hoops together based on your ride height.

The tube clamps allow you to remove the engine cage without cutting/welding in case the motor needs to be removed



Here is the steering shaft that is often necessary, this is due to clearance between the steering shaft and the coilover.  This is needed if the shocks need to be tipped in for tire clearance which is dependant on tire size and wheel backspacing.  It's a $395 option and the upside is that you also get a u-jointed steering shaft instead of the stock rag joint setup.
