Does your truck:
Have driveline shake under acceleration? Wheel hop? Have stacked blocks? Does it ride harsh due to an add-a-leaf?
Or maybe you don’t want to disable the factory overload & bump-stop system.
Traction Blocks Incorporate a lift block with a traction bar.
With the bar attached to the block, the block can't twist.
The U-Bolts run thru the blocks insuring no twisting or kicking. The leverage amplification from the taller block is removed by the traction bar. You get the soft factory ride and factory load capacity with taller ride height.
No loss in articulation.
No loss of wheel travel.
No noise transmission to the frame.
Is seems a few people have strong opinions about blocks.
We hear “Never run blocks they are dangerous”.
Reality is, Ford Dodge and Chevy have used rear blocks for 40 years. If this were a failure point they would have changed the design. They use the blocks to improve the ride quality by keeping the spring arch to a minimum. They also use the block to get ride height at a desired level.
Our system does not run block alone it is an upgraded traction bar / block system. We highly recommend upgrading to our 3/4” U-bolts to increase the clamping force to the axle 2000 lbs more then 5/8” U-Bolts.
We hear “Never stack blocks it is dangerous”.
Reality is aftermarket lift companies have been using stacked blocks for 20 years. 60% of lifted trucks driving around every day have stacked blocks in the rear. If this were a failure point they would have changed the design. This is not any ones first choice of suspension design, but it gets used every day with out failure.
Our system replaces stacked blocks with a single unit that is stronger then the axle tube you are mounting them to.
We hear “All-Spring lifts are the way to go”
Reality is a 6” or 8” “All Spring” lifts eliminates the rear bump-stop and the overload system. With no overload and no bump-stop what stops the tire from hitting the fender at bottom out? If the spring is longer then the OE unit, the rear suspension will get solid when it maxes out the shackle travel. If the spring is not longer, there is nothing stopping tire and fender damage.
This is true of most aftermarket blocks also.
Our system retains the rear bump-stop and the OE overload system.
We hear “Run Add-A-Leafs”
Reality is a 2” Add-A-Leaf rides really harsh. They move your axle 2” from the rear bump stop and the overload system. They increase your ride height but not your bottom out protection. So the bigger tire you installed could go up and hit your fender. The rear spring rate is increased to a higher rate but the front is not. This causes that “bucking” on freeway expansion gaps or any small road imperfection. The front suspension adsorbs the hit and the rear bounces off of it.
Our system retains factory ride.
Reality is all of these systems are used by people every day.
How many people really think thru their rear suspension geometry? The main reason to increase ride height of a truck is to run bigger tires. What good is the system if the tires tear your fender up the first time you really need to haul or tow a real load? The days of “I will never use my truck off road” are gone. Build your truck useable.
This system is solid, you can use them in all high torque applications. They are great for sled pulling, Drag Racing, Mud bogging, sand dune running, Burnout competitions, towing max truck load on loose surfaces like sand or dirt.
We use our parts and want you to use them too.
The Traction BlocksTM are available with two options available in each height. You can get parallel top and bottom surfaces
for a "Flat Block". Or you can a 5 degree + pinion angle correction built into the bottom of the block.
Available heights:
4" Tall, Parallel
5" Tall, Parallel
6" Tall, Parallel
7" Tall, Parallel
4" Tall, 5 Degree + pinion angle change.
5" Tall, 5 Degree + pinion angle change.
6" Tall, 5 Degree + pinion angle change.
7" Tall, 5 Degree + pinion angle change.
8" Tall, 5 Degree + pinion angle change.
9" Tall, 5 Degree + pinion angle change.
10" Tall, 5 Degree + pinion angle change.
The blocks fit most trucks, Ford F150, F250 & F350's, Dodge's & GM's
If your vehicle has the axle below the springs, these should fit.
When you use our adjustable position U-Bolt plate with the block you can change the axle position and move the axle forward 5/8" or 1 1/4". Moving the rear axle forward can help with driveline length and allows for more clearance between the tire and the back of the rear fender.
All OUO U-Bolt plates allow running 3/4" U-Bolts.
This is a good way to upgrade most trucks to 3/4” U-Bolts.
Again, we highly recommend upgrading to our 3/4” U-bolts to increase the clamping force to the axle 2000 lbs more then 5/8” U-Bolts.
The U-Bolt plates are available with or without bump-stop pads. If you have an 8" rear spring and run our adjustable position U-Bolt bump stop plate then you can run your factory upper bump stop location.
The bars are adjustable in length at install, so no mater if you have a short box or a long box the bars will fit your application.
If you just want traction bars
We have a monster bolt on rear axle bracket that is the heaviest on the market. It fits 3 5/8” axle tubes found on
F-250’ and F-350’s. If you have a different axle tube size and want bolt on brackets let us know and we could build them for you.
We also have weld on axle brackets.
They are severely strong and don’t warp your axle tube when welded. They come as a pre-welded assembly raw steel.
The whole system ships UPS
