Product Details

The Bilstein B8 5125 shock absorber is engineered for custom suspension applications where direct-fit solutions aren't available. This high-pressure monotube shock delivers professional-grade performance for builders creating unique suspension setups on trucks, off-road vehicles, and specialty applications.

Key Features:

  • High gas pressure monotube design for superior heat dissipation and consistent damping
  • 46mm piston with self-adjusting deflective disc valving that adapts to changing road conditions
  • Industry-standard 5/8 inch hourglass bushings for universal compatibility
  • Available in multiple lengths and valve rates to accommodate diverse custom builds
  • Choice of eye/eye or stem/eye mounting configurations
  • Precision-tuned valving specific to each shock length

The B8 5125 series gives suspension fabricators the flexibility to build purpose-built systems with Bilstein's legendary monotube technology. Whether you're lifting a truck, building a custom off-road rig, or restoring a classic vehicle, these shocks provide the adaptability and performance needed for professional-quality results.

I was very pleased in the timely manner we received our order.

Parts came in a timely manner and ready to install

The services were very good.

I may need to return the unopened part and i don't see the policy and procedure. Ill have to search on the site page. All legit solid businesses I've worked with in the past made this very clear and up front. Not to say you didn't I just haven't looked yet and its not in your face obvious.

Looks absolutely great on truck- thanx

Autoplicity has great prices and customer service. Shipping is fairly fast too. Ordered product on Monday and it was shipped on Wednesday. Will make future purchases with this company.

Very pleased with the service and quick shipping. Checked out through Amazon payments without any issues. Item ordred was the Hella Supertone Horns. Arrived in original box and packaging. Will not hesitate to order from Autoplicity in the future.

Great prices very fast shipping!!!

Easy and fast. Order arrived very fast. Thanks.
