King Shocks 20AB422-104 2.0in Bump Stop 2in Weld-In Mount Sleeve 4130 Chromoly

Vehicle Fitment

• Universal - for use with King Shocks 2.0" diameter bump stop bodies in custom suspension builds, long travel kits, pre-runner trucks, desert race vehicles, and performance overland rigs

Fitment Notes

• Mounting sleeve only - King Shocks 2.0" bump stop body is NOT included; sold separately (see BS2020 for 2" travel or BS2040 for 4" travel)
• Compatible with King Shocks 2.0" diameter bump stop bodies - not compatible with King 2.5" bump stop bodies
• Weld-in installation required - this sleeve is designed to be welded into a custom chassis, suspension bracket, or bump stop tower; no bolt-in option
• Sold individually (single sleeve) - order quantity as needed for your build
• Companion 4" sleeve available as 20AB422-103 for applications requiring longer mounting depth

Features

• Precision machined from SAE 4130 chromoly steel - same high-strength material used throughout King's race shock lineup for maximum durability and weld integrity
• 2" sleeve length accommodates tighter chassis packaging where a 4" sleeve would not fit - commonly used in front bump stop towers on long travel and pre-runner builds
• Precision bored to exact tolerances for a secure, snug fit around the King 2.0" bump stop body without pinching or distorting the housing
• Weld-in design allows the sleeve to be integrated directly into custom fabricated bump stop towers, A-arm tabs, or chassis mounting points
• Compatible with all King Shocks 2.0" bump stop accessories including nylon strike pads, Schrader covers, and valving components
• Sold as a genuine King Shocks replacement/accessory part - same quality as OE King race components

Product Description

The King Shocks 20AB422-104 is a 2" weld-in mounting sleeve for King's 2.0" diameter hydraulic bump stop bodies. Precision machined from SAE 4130 chromoly steel - the same high-strength alloy used throughout King's performance and pure race shock lineup - this sleeve is designed to be welded directly into a custom bump stop tower, chassis bracket, or fabricated mounting point, creating a clean, secure housing that accepts the King 2.0" bump stop body with a precision fit. The tight bore tolerance ensures the bump stop body slides in without pinching or distorting the housing, preserving proper piston alignment and seal integrity.

The 2" length makes this sleeve the right choice for chassis packaging situations where a longer 4" sleeve (20AB422-103) would intrude on surrounding components or exceed available mounting depth - a common constraint in front bump stop towers on long travel IFS, A-arm, and pre-runner builds. The sleeve is sold individually and does not include a bump stop body. King's 2.0" bump stops are available separately in 2" travel (BS2020) and 4" travel (BS2040) configurations, each featuring the same micro-polished shafts, advanced seal technology, unique piston design, and nylon strike pad that define King's race-proven bump stop line.
