Product Details

The QA1 DD52-300 Proma Star is a high-performance double-adjustable coil-over shock absorber engineered for serious motorsport and performance street applications. Built by QA1 Precision Products — a trusted name in American-made suspension components — the Proma Star series delivers race-proven damping control with the adjustability needed to dial in your suspension for any track or driving condition.

Featuring independent compression and rebound adjustment, the DD52-300 allows drivers and tuners to fine-tune handling characteristics without removing the shock from the vehicle. The 52mm body diameter provides exceptional oil capacity and heat dissipation, keeping damping performance consistent lap after lap.

Key Features:

  • Double-adjustable — independent compression and rebound clickers for precise damping tuning
  • 52mm shock body — large-diameter aluminum body for improved heat management and durability
  • Coil-over design — accepts coil springs for integrated spring/shock assembly
  • Rebuildable and re-valveable for long service life and custom tuning
  • Manufactured in the USA by QA1 Precision Products
  • Threaded body for ride height and preload adjustment
  • High-quality seals and internals for consistent, fade-free performance

The QA1 Proma Star DD52-300 is a top choice for circle track, drag racing, road course, and performance street builds where precise, repeatable suspension control is essential.

Great service

The only thing it said free shipping in the advertisement and it charged me $4.99 which is still reasonable

Quick easy and great prices on the product I need.

It was easy

Finding and applying the part was fairly easy. Not real crazy about the shipping insurance though. I think it protects you more than me. If it get lost in shipping, I cancel the charge. Most major credit cards have that built in.

'Ordered lug nuts for my new wheels-shipping was fast and the price was good. Everything arrived as expected and worked well. Smooth overall experience.'

Your online system would not allow me to put my Alaska address for billing, even though the order was to be shipped to Texas. I sent repeated emails requesting a phone call and no one would call me or provide me a number to call.

The item I bought was one to replace something I thought I had accidentally thrown away. A couple days after the boatplicity item arrived I located the like item I already had. I initiated the return process with boatplicity, as I no longer had need of the item. I completed the return request stuff and it said I would be contacted to continue the process but no one has contacted me.

Great! Equal to any
