Description

Overview

The Westin 27-1455 mount kit holds Sure Grip molded running boards on 1999 to 2007 Chevrolet Silverado and GMC Sierra pickups. It is a direct-fit kit for 1500, 2500, 2500 HD and 3500 models.

Coverage spans several series and trims across both brands, so match your exact model, year and trim rather than relying on the overall year range.

Checking the mounts over time

Running board mounts carry the weight of a passenger climbing in and out, and they absorb road and trail vibration every time the truck moves. Over time, the points where the bracket meets the frame or cab can loosen, so check fasteners for tightness and look for cracks or flexing around the bracket.

Surface rust on steel brackets is common on trucks driven in wet or salted conditions. Clean and treat any spots early. Because the boards sit low, they also affect approach angle and side clearance, and they can strike rocks or stumps on trail work. Replacing a worn mount is usually simpler than repairing one, and it is worth inspecting the boards at the same time since both parts wear together.

  • Tighten fasteners after the first few drives
  • Look for cracks or bent brackets near the frame
  • Treat rust early on exposed steel
  • Replace boards and mounts together when either shows wear

Questions & Answers

Does the Westin 27-1455 fit a 2005 GMC Sierra 1500?

Yes, it fits the 1999–2006 GMC Sierra 1500 in Base, HT, SL, SLE and WT trims. Confirm your trim matches before ordering.

Does it fit a 2008 Chevrolet Silverado?

No. Silverado coverage ends with the 2007 Classic models, so 2008 trucks are not covered. Confirm fit for your vehicle's year, model and trim before ordering.

Which 2500 and 3500 trims are covered?

Silverado 2500 and 3500 entries name Base, LS, LT and WT trims. Sierra 2500 and 3500 entries name Base, SL, SLE and WT trims. Confirm your model before ordering.

How often should running board mounts be checked?

Check them after the first few drives, then periodically, especially after trail use or winter road salt exposure. Look for loose fasteners, cracks and rust, and tighten or replace parts as needed before the boards carry passenger weight again.

Can running boards affect off-road clearance?

They can. Boards sit low on the side of the truck, so they reduce some approach and side clearance and can catch on obstacles. Removing boards before serious trail work is a common choice for drivers who need maximum clearance.
