Product Details

The QA1 DS501-100V1 is a Pro-Rear weld-in coilover conversion kit designed for drag racing, street performance, and street rod applications. This single-adjustable system delivers simultaneous compression and rebound damping control, allowing you to dial in the ideal ride quality and handling balance for your build.

Featuring QA1's Proma Star single-adjustable coilover shocks, the DS501-100V1 uses lightweight aluminum construction with a precision-machined aluminum piston, PTFE piston band, and a 5/8" centerless ground, hard chrome-plated solid piston rod. A three-step sealing system ensures long-lasting durability and leak-free performance. Each shock is 100% dyno tested and serialized, and can be revalved or rebuilt by the QA1 factory or an authorized service center.

Ride Height Adjustability: The axle-mounted brackets provide 3/4" increments of adjustment, while the coilover shock allows for additional fine-tuning — combining for up to 9" of total ride height adjustability to achieve your desired stance.

Kit Includes:

  • (2) Single-adjustable Proma Star coilover shocks
  • (2) 100/200 lb/in variable-rate springs
  • Axle mount bracketry designed for 3.25" axle tubes
  • Upper shock mount tubing (1-5/8" diameter x .095" wall, 40" long)
  • All mounting and spring mounting hardware

Key Features:

  • Single-adjustable simultaneous compression and rebound (DS) valving
  • Evenly spaced valving changes — no jumps between adjustment clicks
  • Lightweight aluminum shock body with ride height adjustability
  • Weld-in installation — designed for 3.25" axle tubes
  • Double shear bracketry for added strength in street and race use
  • Revalveable and rebuildable by QA1 or authorized service centers
  • Requires QA1 spanner wrench T114W or T115W (sold separately)
  • Made in the USA — manufactured in Lakeville, Minnesota

A limited lifetime warranty is available on QA1 shock absorbers when registered at QA1.net/Warranty. Note: Welding is required for installation of this kit.

Amazed at how great the prices were compared to Summit. Website is simple,but easy to use.

simple and easy

great website

Thanks for keeping it simple

I just ordered and was fast.. just waiting to see how long they take to arrive

easy ordering

If the battery is truly in stock...

Autoplicity has the best prices around! They were quick to email a confirmation of the order, shipment, and delivery. I was VERY impressed! I also received my order earlier than I thought, which is always a plus. Will definitely do business with them again! Thanks!

the product reviews all seem to be reviewed of autoplicity's service instead of the item being viewed. either way, the shocks ordered were the right ones w/ all the parts w/ it. autoplicity's item descriptions could be a little more clear and/or explicit like specifying which side a part applies to instead of just "passenger or driver" side, or "can be used in either said"

shopping was easy and quick

you have what i need at a great price

U guys R fantastic fast shipping and good prices

Good so far...
