US Car Tool does it again. Well known for their chassis stiffening products, US Car Tool has now created a kit to help E-Body Mopar car owners get even better performance by providing up to 9" more room for rear tires. Anyone who has ever looked underneath the rear end of a Mopar notices the leaf springs are in the way of really wide tires / wheels. Racers and chassis fabrication shops have been moving these in for years, and believe me, it is not as easy as it sounds. Why do you think all the race cars ads say "Hooks hard and goes straight", unless going straight was not the norm? The US Car Tool leaf spring relocating kit is self aligning off the factory leaf spring mounting holes and includes instruction on how to cut the factory frame rails, locate and weld in the new front and rear mounts and measure to be sure you are straight and square. This kit won't make you a chassis shop, but it will help an advanced hot rodder gain up to 9"of tire tread space in the back of that Mopar!

Includes:

  • Set Of Pre-Fabricated 3/16 thick front spring buckets with attached tabs to precisely locate using the factory spring hanger mounting (assures correct placement)

  • New rear spring hanger mounting rail with shackle sleeve (uses factory stock rear shackles / bushings)

  • New USCT rear spring perches with extended pad design for better spring wrap control
  • Detailed Set Of Instructions with pictures

Frequently Asked Questions:

Whats the biggest wheel and tire i can fit after installing a spring relocation?

Its hard to give sizes that are concrete due to the shape of the wheelhouse, ride height, and wheelbase. The USCT Spring relocation on an E-Body Challenger or Cuda moves the factory leaf springs inboard a full 4.5" per side. When combined with a mini tub kit, you will have 15" clearance between the frame and the outer quarter panel lip in the center of the tire. You can even roll the lip for more room, but 15" is an enormous amount of room. When our mini-tub kit is installed with the rear spring relocation kit, this will allow for maximum tire size. The actual size tire that can be fit in the wheelhouse will depend on many factors including wheelhouse shape, size, ride height of vehicle, wheel backspace, wheel diameter, tire diameter, tire width, axle width. All these play an important part in selecting the correct size for your application.

Examples of tire size and wheel combinations we have used on E-bodies:

1971 Plymouth Cuda: 355x30x19 Tire

Does the rear end need to be shortened?

The rear may need to be shortened depending on your wheel offset, this will require mock-up and measuring to be correct.

Will the rear seat still fit?

The rear seat is not impacted by the spring relocation. If you also install the mini-tub kit you may need modification to the rear seat.

Will the rear valence still fit?

The rear valence may need to be modified for rear shackle clearance on some cars.

Do the seat belts still work?

Yes, Spring relocation does not impact the seat belt mounting.

Is the stock exhaust impacted?

Moving the leaf springs inboard will impact the factory rear exhaust resonators. You will need to modify a factory exhaust system to fit with a spring relocation.

Does this require different shock?

If you narrow the rear, the shocks would ideally need to be shorter and will also depend on ride height, so mock up and measurement is required to get the right length.

Does this kit work with Super Stock Springs?

Yes. We can also locate custom spring mounting holes in the spring buckets if you have a special application.

Do you install these for customers?

Yes we do, just give us a call to schedule an installation appointment.

How much work is required for the install?

We allow 1 days to perform a spring relocation installation in our install center.

We have more pictures of the spring relocation install process on our website at www.uscartool.com under the pictures section.
