Can I pick up my order or have it installed at your shop?

Absolutely. We offer local pickup on most products and full professional installation at our shop in Washington, MO. Whether you just want to grab your parts or have our techs handle the install, we’ve got you covered. Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

Description

The factory steering gear in these trucks has always been a weak spot—until now. PSC’s BIG BORE XD® Steering Gear is built to handle the demands of lifted trucks, oversized tires, and serious off-road use. With a beefed-up 45mm sector shaft and upgraded roller bearings, this gear eliminates the deflection and seal failures that plague OEM units.

Whether you’re running a standard setup or PSC’s Cylinder Assist® system, we’ve got the gear for you. All-new components, no remanufactured parts, and PSC’s proven durability make this a must-have upgrade for your GMC 2500/3500 or Hummer H2.
