How to make a Peak Suspension warranty claim
- Peak expects installs to be done by a qualified mechanic experienced with suspension work; keep your install receipt
- Photograph the issue and gather your order details before removing anything
- Failed shocks get shipped to Peak for inspection; if Peak finds the failure wasn't a defect (neglect, install damage and so on), the owner pays for service, parts and shipping
- Shipping to and from Peak on warranty claims is the purchaser's cost

The Peak Suspension Billet Upper Control Arms – 25+ Toyota 4Runner/LC250 is a Peak Suspension part built for 2025+ Toyota 4Runner / Toyota Land Cruiser. Peak designs and machines its suspension in the USA, and this piece is made for the platform rather than adapted from something generic.
Factory upper control arms run out of room once a truck is lifted: ball joints bind, caster and camber get hard to correct, and droop gets limited. Peak's billet upper control arms are CNC-machined from solid billet aluminum with ProBearing uniballs installed, with geometry built to restore alignment range and add travel on a lifted truck. They are a clean, strong upgrade if you are running a leveling kit or coilovers.

Fitment
Fits 2025+ Toyota 4Runner / Toyota Land Cruiser. Peak's notes: 2025+ Toyota 4Runner; 2024+ Toyota Land Cruiser LC250. Not sure about your trim or drivetrain? Ask before you order.
Install notes
Upper control arms change alignment, so book an alignment after install. They pair naturally with a coilover install since the front end is already apart.
Lead time and shipping
Peak Suspension ships this direct from its shop, and many Peak kits are built to order, so ship dates move with demand. We'll confirm the current lead time on request. Peak's own advice is a good one: don't book your install appointment until the parts are in hand and you've checked the boxes.
Warranty
Peak covers the parts it manufactures with a limited lifetime warranty against defects for the original purchaser; Peak shocks carry one year, and springs, bushings and heim joints are wear items. Read the Peak Suspension warranty summary for details.

Peak Suspension Billet Upper Control Arms – 25+ Toyota 4Runner/LC250 FAQs
Do I need an alignment after installing this?
Yes. Any change to ride height or control arm geometry moves your alignment, so book a professional alignment right after install.
Why replace the upper control arms when lifting?
Once the front is raised, factory upper arms tend to bind and run out of alignment adjustment. Aftermarket arms with corrected geometry bring caster and camber back into spec and free up droop travel.
How long does Peak Suspension take to ship?
Peak ships direct from its shop, and many kits are built to order, so lead times change with demand. Call or text us at (920) 249-7744 for the current ship date, and wait until the parts arrive before you book an install appointment.
What warranty comes with Peak Suspension parts?
Peak covers parts it manufactures with a limited lifetime warranty against defects for the original purchaser. Peak shocks carry a one-year warranty, and springs, bushings and heim joints are treated as wear items. See our Peak Suspension warranty page for the full summary.
Will this fit my truck?
This listing is for 2025+ Toyota 4Runner / Toyota Land Cruiser. Trim, drivetrain and factory options can matter on suspension parts, so if anything in the notes above does not match your vehicle, call or text us at (920) 249-7744 before ordering.
