An LCG chassis kit replaces the SCX24's frame rails with lower-mounting ones, dropping the battery and electronics 5 to 10mm to lower the center of gravity. Background on what LCG actually does is in the all about SCX24 chassis explainer. This article is the shortlist of which kits I'd actually buy.
The quick verdict
- Best budget: INJORA Universal LCG Carbon Fiber. Around $18.
- Best mainstream: Treal LCG Carbon Fiber. $35 to $50.
- Best aluminum: RCAWD aluminum LCG. $30 to $40.
- Best premium: LGRP or Mofo RC brass-and-carbon hybrid chassis. $80+.
What you're actually buying
An LCG kit is a pair of redesigned frame rails plus the small parts needed to bolt the truck back together. Specifically:
- Left and right side plates (carbon fiber, aluminum, brass, or titanium)
- Two or three cross-braces
- A battery tray plate
- Receiver and ESC mount plates
- An angled skid plate (5 to 12 degrees)
- Velcro strap for the battery
- M2 and M1.4 hardware
You reuse the transmission, links, axles, shocks, and body posts. Some kits change link mount positions; check before you buy if you have non-stock links.
INJORA Universal LCG Carbon Fiber
Around $18. The reference budget pick. Carbon fiber side plates (1.5 to 2mm), aluminum cross-braces, aluminum skid. Fits all SCX24 standard-WB models (Jeep, Deadbolt, Bronco, C10, Base Camp). Drops the battery and ESC 5 to 8mm. About 35g complete.
Trade-offs: the carbon is on the thinner side and can flex slightly under heavy impact. Aluminum cross-braces are fine but not high-end. Hardware is acceptable. For $18 it's an unmissable value.
Treal LCG Carbon Fiber
$35 to $50. Better fit and finish than INJORA. Thicker carbon. More shock mounting points so you can fine-tune shock position. Comes with more cross-braces. Around 40 to 45g complete. Treal's mainstream LCG offering.
RCAWD aluminum LCG
$30 to $40. CNC aluminum side plates instead of carbon. Heavier (around 70g complete) but practically indestructible. Better for trail builds where impact protection matters more than gram-shaving. Anodized in several colors.
LGRP / Mofo RC brass-and-carbon hybrid
$80+. Premium tier. Brass cross-braces or skid plate paired with carbon side plates. The brass doubles as ballast, lowering the CG even further. Comp-grade machining. Best appearance. Best for builds where you want LCG plus low-mounted weight in one upgrade.
Honorable mentions
- INJORA brass-weighted LCG. Around $35. INJORA's LCG kit with brass cross-braces. Cheap way to get the brass+LCG combo.
- Yeah Racing aluminum LCG. Around $40. Similar in spec to RCAWD, slightly different design.
- 3D-printed LCG chassis. Plenty of free STL files on Printables. If you have a printer, $5 of filament gets you a working LCG. Strength varies by print quality and material.
How to choose
- Cheapest functional upgrade? INJORA Universal Carbon. $18 and done.
- Comp build? Treal or LGRP. The extra shock mount points and machining quality matter.
- Trail build with rocks? RCAWD aluminum. Won't crack on impacts.
- Looking for the most CG drop? Pair an LCG chassis with brass cross-braces (INJORA brass LCG, or any LGRP/Mofo hybrid).
Install notes
Plan a full chassis tear-down and rebuild. About 1 to 2 hours.
- Take photos as you go. The wire routing on an LCG chassis is tighter than stock.
- Blue threadlock every M2 and M1.4 screw.
- Check that body posts still align. Some bodies sit too high or too low; spacers fix this.
- Re-set shock pre-load after the install. The chassis sits differently and shock geometry changes.
Where LCG sits in the overall plan: it's Stage 6 alongside or instead of portals. See the staged upgrade path. For builds chasing maximum geometry change, do LCG plus portals together.
