SPC 35106 Replacement Sealed Ball Joint Kit 2021+ F-150/Lightning

Vehicle Fitment

• 2021-2025 Ford F-150 (all trims sharing the SPC 25685 upper control arm, including Raptor)
• 2022-2025 Ford F-150 Lightning

Fitment Notes

• This is a replacement ball joint kit for use with SPC's 25685 front upper control arm - it is not a standalone control arm. Confirm the customer already has (or is purchasing) the matching SPC 25685 control arm before selling this as a replacement part.
• This part supersedes the ball joint originally supplied with early production 25685 control arms; SPC updated the design to a sealed, maintenance-free unit under this new part number.

Fitment / Ownership Note

• Some F-150 Tremor/Raptor owner discussions reference ongoing concerns about SPC ball joint durability on this platform, even with the newer sealed 35106 design. This is owner-reported forum discussion, not a manufacturer defect notice - worth surfacing to customers as a point of reference rather than omitting, particularly given this is a front suspension safety component.

Product Description

The SPC 35106 is a sealed, maintenance-free replacement ball joint kit designed specifically to service SPC's 25685 front upper control arm on 2021+ Ford F-150 and F-150 Lightning trucks. Rather than replacing the entire control arm when a ball joint wears out, this kit lets an owner rebuild the existing arm with SPC's updated joint design, which uses a fully sealed boot and E-nickel-coated ball stud in place of the earlier serviceable joint.

The forged steel housing and one-piece polymer race are built to maintain the same adjustability the original 25685 arm was designed for, while the sealed, pre-greased design removes the maintenance burden of periodically re-greasing a joint that sees constant articulation on a lifted or off-road-driven truck.

Because this joint is specific to SPC's 25685 control arm and has effectively superseded that arm's original ball joint, confirm the customer's control arm generation before selling this as a replacement - and given that some owners of lifted F-150 platforms have raised durability questions about SPC ball joints on this application even after the sealed redesign, it's worth setting expectations rather than presenting this purely as a guaranteed fix for prior joint failures.
