Fitment Notes

• Regular Cab / Standard Cab ONLY - this kit does NOT fit Extended Cab configurations; use Prothane 7-116 for Extended Cab models
• Fits both 2WD and 4WD configurations on all compatible models
• Kit includes body mounts and radiator support bushings - does not include bed mount bushings
• Hardware (bolts, washers) is NOT included - reuses existing OEM body mount fasteners
• Available in red (7-115) and black with graphite (7-115-BL) - performance is identical between colors
• Does not fit 2005+ Colorado/Canyon (different platform)
• Professional installation recommended; body lifting equipment is required to access mount positions
• No grease is required or included - body mount bushings compress rather than rotate

Features

• Premium-grade polyurethane construction significantly outlasts OEM rubber body mounts - resists compression fatigue, UV degradation, road chemicals, and oil contamination that cause rubber mounts to collapse and fail
• Covers all body mount and radiator support bushing positions in the Regular Cab S10/S15/Sonoma chassis for a complete underbody refresh in one kit
• Restores proper body-to-frame and radiator support alignment - eliminates looseness, body wobble, and misalignment caused by deteriorated OEM rubber mounts
• Reduces unwanted cab vibration and road noise transmitted through failed mounts - restores a tight, solid cab feel for both daily drivers and off-road builds
• Provides the necessary rigidity for improved chassis feel while retaining sufficient resilience to keep everything quiet over long hauls and rough terrain
• Precision-fabricated for an exact fit - dimensionally matched to OEM body mount locations for a direct drop-in using existing hardware
• Suitable for street driving, daily use, work trucks, restorations, and off-road applications
• Backed by Prothane's lifetime warranty to the original vehicle purchaser
• Made in the USA

Product Description

The Prothane 7-115 is a 12-piece polyurethane body mount and radiator support bushing kit engineered for 1982-2004 Chevrolet S10 Pickup and 1982-2004 GMC S15 Pickup / Sonoma Regular Cab trucks in both 2WD and 4WD configurations, as well as the 1991 GMC Syclone and the 1996-1999 Isuzu Hombre. This comprehensive kit covers every body mount position and the radiator support bushing in the Regular Cab S-series chassis, replacing the original rubber bushings with Prothane's precision-molded polyurethane compound in a single purchase. Over the decades-long production run of the S10 and S15 platform, OEM rubber body mounts are one of the first items to deteriorate - compressing, cracking, and eventually losing their ability to properly locate the body on the frame, which manifests as cab wobble, door alignment issues, and increased noise and vibration from the chassis.

Prothane's polyurethane compound is formulated to withstand the sustained compression loads and environmental conditions that degrade rubber over decades of use. Unlike rubber, polyurethane resists degradation from UV exposure, road grime, engine fluids, and oil contamination - making it an ideal long-term replacement for body mounts that are subjected to constant weather and road exposure. Because body mount bushings compress rather than rotate, no grease is required or included in the kit. All bushings are dimensionally matched to the OEM mount locations for a direct drop-in fit using the existing body mount hardware, which is not included in the kit.

It is important to note that this kit is designed exclusively for Regular Cab / Standard Cab S10, S15, and Sonoma trucks. Extended Cab owners should use Prothane part number 7-116. This kit is ideal for high-mileage restoration builds, daily drivers looking to refresh a tired chassis, and off-road S10 builds where proper body-to-frame integrity is essential. The 7-115 ships in red; the identical kit in black with graphite additive is available as 7-115-BL - both colors perform identically. All Prothane body mount kits are made in the USA and backed by a lifetime warranty to the original vehicle purchaser.
