Product Details

The QA1 RCK52445 is a bolt-in rear coilover conversion kit featuring the top-tier MOD Series shock absorbers, designed for 1973–1977 GM A-Body vehicles. This complete kit transforms your factory rear suspension into a fully adjustable coilover setup with no cutting or welding required.

MOD Series QuickTune Technology:

  • 4-way adjustable valving with independent control over high and low-speed compression and rebound
  • Dry modular valve packs can be swapped out in minutes — even with the shock still installed on the vehicle
  • Comes standard with medium compression and rebound valve packs; soft and firm configurations also available
  • Expansive force curve capability for precise tuning to your exact driving preferences

Ride Height Adjustability:

  • Fully threaded aluminum shock body allows for ride height fine-tuning
  • Adjust weight balance for improved handling and the perfect stance

High-Travel Springs:

  • Includes two 12-inch springs rated at 200 lb/in
  • Lightweight, American-made design with fewer coils and smaller wire diameter for increased travel
  • Reduces unsprung weight and improves suspension reaction speed

Kit Includes:

  • 2 MOD Series aluminum coilover shocks
  • 2 high-travel 12-inch springs (200 lb/in spring rate)
  • All mounting brackets and hardware for a complete bolt-in installation

Additional Features:

  • 100% dyno tested and serialized
  • Rebuildable and revalveable by QA1 factory or QA1 authorized service centers
  • Proudly made in the USA at QA1's Lakeville, Minnesota facility
  • Compatible with QA1's adjustable front coilover kits for a full suspension upgrade

Awesome anf easy

Good price on good tires

Great experience

You folks had the best price for this unit, hands down. I regret not being able to comment on this camera since I haven't been out fishing with it yet. But I can say the purchase experience was trouble free and it got here in the time frame promised. Thanks!!

I ordered the end links for quite a bit cheaper from THMotorsports that I was able to find them anywhere else including the manufacturer's website, Ebay & Amazon. I expected the shipping to take a week but within two days I was surprised with a package on my doorstep. So early, in fact, that I wondered what the package contained.

Shipping was lightning fast! Received order as described and in great condition. Expectations exceeded!
