Step-by-step guide to swapping VS4-10 frame rails. Learn the tools, order of work, and common mistakes to keep your chassis straight and your build clean.

Quick Answer

To install VS4-10 frame rails, remove the old rails, transfer all brackets and skid plate, then bolt the new rails in place using a cross-pattern torque sequence. Take your time to keep the chassis square.

Why Frame Rail Alignment Matters

The VS4-10 frame rails are the backbone of your chassis. If they aren't aligned, you'll get binding in the driveline, uneven tire wear, and poor suspension geometry. A little extra care during installation saves you from chasing handling issues later.

The Vanquish VS4-10 Frame Rails (SKU VPS10112) are a direct replacement for the VS4-10 chassis family, including the Chassis Kit, Origin Limited, Pro, and Ultra. Because they're designed for these specific models, the holes line up perfectly—but only if you install them in the right order.

Tools You'll Need

You'll need a 1.5mm, 2mm, and 2.5mm hex driver, a small flathead screwdriver for prying stubborn parts, threadlocker (blue), and a clean, flat work surface. A caliper can help verify the frame rails are parallel, but it's optional.

Step-by-Step Installation

Prepare the Chassis: Place the chassis on a clean, flat surface. Remove the body, shocks, and any electronics that block access to the frame rails. Take photos of the current setup for reference. Check that all screws are accessible before starting; if not, remove more components.
Remove the Old Frame Rails: Starting from the rear, loosen and remove the screws holding the old frame rails. Keep the brackets, skid plate, and cross members attached to the old rails if possible, or set them aside in order. Keep hardware sorted by location to avoid mix-ups during reassembly.
Transfer Brackets and Skid Plate: Move the skid plate, transmission mount, and any brackets from the old rails to the new ones. Use a small amount of blue threadlocker on each screw. Ensure the skid plate is centered; misalignment here will cause driveline binding.
Mount the New Frame Rails: Position the new rails on the chassis, aligning the holes with the skid plate and cross members. Start all screws by hand before tightening any of them. Do not tighten any screw until all are started; this prevents cross-threading.
Tighten in a Cross Pattern: Tighten the screws gradually in a cross pattern, working from the center outward. This ensures even pressure and keeps the rails parallel. Check that the rails are parallel by measuring the distance at front and rear; adjust if needed.
Reinstall Components and Test: Reinstall the shocks, electronics, and body. Cycle the suspension through its full travel and check for any binding or rubbing. If the driveline binds, loosen the skid plate screws and re-center it before retightening.
