Product Details

The QA1 Precision Products DS501-12175V is a complete Pro-Rear coilover shock system designed for drag racing and performance applications requiring adjustable rear suspension. This comprehensive kit provides everything needed for a professional-grade coilover conversion.

Kit Includes:

  • Two single-adjustable custom mount coilover shocks with 12-position compression damping control
  • Two dual-rate progressive springs with 175 lb/in primary rate and 350 lb/in secondary rate
  • Complete mounting hardware for installation

Key Features:

  • Single-adjustable damping allows fine-tuning of compression control for optimal weight transfer
  • Variable rate springs provide a softer initial ride with firmer control during hard launches
  • Custom mount design accommodates a wide range of vehicle applications
  • High-quality construction with precision-machined components for consistent performance

This Pro-Rear system is ideal for racers and performance enthusiasts seeking precise control over rear suspension behavior, particularly for drag racing applications where controlled weight transfer and consistent 60-foot times are critical.

I got charged plenty for shipping, but it was delivered in 2 days. Need free shipping option for larger orders. Satisfied with delivery time? Yes. Satisfied with delivery charge? No.

easy website to navigate, prices fair

Awesome pricing. Easy filtering to get the exact item.

They gave proper fitment details unlike other sites which ensures I'm getting the right parts

Item should be boxed...the plastic bag it shipped in was torn and half gone...luckily the shipping label was still on the torn bag

I will definitely buy again

Great

Great customer service and support. a live person answered the phone and was able to reccomend the correct product for my vehicle. Best price online too........i woould most absolutely use them again! Great company!

Right item, right price !

Easy to find the part needed. Hope the remainder of the order, shipment, and delivery goes just as smoothly.

Lowest prices of what I was looking for and super fast shipping!!

I was a little concerned at first. They advertise same-day order processing, and they said my part was in stock. However, my order took three business days (plus the weekend) to finally ship. As long as the right part arrives, I'll be happy. The price was $100 less than everywhere else, so that can't be beat.

Great prices, great service, fast shipping!

Autoplicity best price on the web,FAST delivery, ordered wed. afternoon and received friday. AAAA++ RATING Will be ording from in the near future.

SO far, so good. We ordered a new Weathertech Trunk Liner from Autoplicity for our new VW SportWagen. We were pleased to find exactly what we were looking for for $50 less than other locations.

Great merchant! I would most certainly would do business with them again. Customer Service was extremely helpful and my order shipped quickly.
