ICON Tubular UCA Replacement Bushing and Sleeve Kit for 2001-2010 Silverado 2500/3500 and Sierra 2500/3500

The ICON Vehicle Dynamics Tubular UCA Replacement Bushing and Sleeve Kit restores the inner pivots of ICON tubular front upper control arms on 2001–2010 Chevrolet Silverado 2500 and 3500 and GMC Sierra 2500 and 3500 trucks. The kit services one pair of control arms (part numbers 78550 and 78550DJ) and returns worn inner pivots to like-new condition using genuine ICON components.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Restore Pivot Feel Without Replacing the Arm

Over time, inner pivot bushings wear and introduce slop into the front suspension, affecting steering feel and alignment stability. Replacing only the bushings and sleeves, rather than the entire control arm, recovers that precision at a fraction of the cost. Because these are genuine ICON Vehicle Dynamics parts made to the same specifications as the originals, the fit and durometer match what came on the arm from the factory.

Application-Specific Materials

The polyurethane hat bushings in this kit are formulated for the pivot loads and articulation angles of ICON's tubular front upper control arms, not adapted from a generic bushing catalog. Delrin load rings reduce friction at the pivot interface, and the CNC-machined steel sleeves are zinc-plated to resist corrosion in the bore.

Features

• Genuine ICON parts: original-specification components, not aftermarket substitutes
• Polyurethane hat bushings: application-specific formulation for ICON tubular UCAs
• Delrin load rings: low-friction pivot interface
• CNC-machined steel sleeves: zinc-plated for corrosion resistance
• Full kit: complete bushing and sleeve set for one pair of control arms

Specifications

Who This Is For and Isn't

This kit suits owners of 2001–2010 Chevrolet Silverado 2500/3500 or GMC Sierra 2500/3500 trucks who have already installed ICON tubular front upper control arms (part numbers 78550 or 78550DJ) and need to rebuild worn inner pivots.

This kit does not fit any other control arm brand or model, and it does not include the control arms themselves. It is not a universal bushing kit and does not fit ICON control arms outside part numbers 78550 and 78550DJ.
