2010-2026 Raptor Lower A-Arm Slot Block kit

• Full center lock plates
• Full offset plates

The plates are set up for the right or left side.

From the factory, the lower control arm pivots are held by bolts that sit in slotted mounts, so alignment can be adjusted. Under normal driving, bolt clamp load keeps them where they were set. Hit something hard enough off-road and the bolt can move in the slot, which pulls camber and caster out of spec and leaves the truck driving differently than it did that morning.

Slot blocks, also called camber lockout plates, fill that slot so the arm cannot walk. The center and offset plates still give you alignment positions to choose from, so you lock in a setting rather than lose the ability to adjust.

The Foutz Motorsports team developed these plates while off-road racing a 2017 Ford Raptor. They provide the strength needed to keep the lower arms in place, in a simple design that keeps alignment adjustable through the offset and center block plates.

• Gen 1 Ford F-150 Raptor: 2010–2014
• Gen 2 Ford F-150 Raptor: 2017–2020
• Gen 3 Ford F-150 Raptor: 2021–2026
• Raptor R: 2023–2026

What does a slot block kit do?

It keeps the lower arms from shifting in their slotted mounts, so the truck holds its alignment under hard use.

Can I still adjust alignment?

Yes. The offset and center block plates give you alignment adjustment while still locking the arm in place.

Which Raptors does it fit?

Gen 1 (2010–2014), Gen 2 (2017–2020) and Gen 3 (2021–2026), including the Raptor R.

Does it work with the lower control arm reinforcement bracket?

Yes. The updated kit is compatible with the Lower Control Arm Reinforcement Bracket for Gen 1, Gen 2 and Gen 3 Raptors.

Do I need anything else?

We recommend the longer lower arm bolt kit for the rear lower control arm bolts. See below.
