CKD0401 – KAOS CNC ALUMINUM SERVO HORN SAVER (25T, BLACK ANODIZED) – DL-SERIES
The CEN Racing CKD0401 KAOS CNC Aluminum Servo Horn Saver is a 25T, black-anodized CNC aluminum steering component for CEN DL-Series applications. CEN's current product page specifically limits fitment to the standard, non-lifted F450 configuration.

CONFIRMED PRODUCT DETAILS
- Manufacturer: CEN Racing
- Product line: KAOS / DL-Series
- Part number / SKU: CKD0401
- Product type: Servo horn saver
- Servo spline: 25T
- Construction: CNC aluminum
- Finish: Black anodized
- Confirmed fitment: Standard stock F450, non-lifted
CRITICAL FITMENT NOTE
CEN explicitly states that CKD0401 does not fit lifted DL-Series trucks. CEN further states that this horn fits the standard stock F450, non-lifted configuration. Do not purchase based on the 25T spline alone if the truck has a lift conversion or altered steering geometry.

25T SERVO SPLINE
The servo output spline must match the horn's 25T specification. Verify the servo manufacturer's spline standard before installation; spline count alone is a fitment requirement independent of the truck's suspension height or steering-link geometry.
SERVO-SAVER FUNCTION
A servo-saver mechanism provides controlled compliance between the servo output and steering linkage so impact loads are not transmitted as a completely rigid connection. CEN identifies CKD0401 as a servo horn saver, but does not publish a spring rate, preload specification, release torque or quantified reduction in servo shock load.
INSTALLATION & SETUP NOTES
- Confirm the truck is a standard-height, non-lifted F450 / compatible DL-Series configuration.
- Verify the steering servo uses a 25T output spline.
- Center the servo electronically before installing the horn.
- Confirm full spline engagement before tightening the retaining hardware.
- Cycle the steering from lock to lock and check drag-link, chassis, axle and Panhard clearance.
- Set steering endpoints so the servo does not continue driving after the steering reaches its mechanical limit.
- Recheck horn and linkage hardware after the first driving sessions.
CUSTOMER-REPORTED EXPERIENCE
CEN's current CKD0401 page shows 8 customer reviews. Customer comments are treated as user experience only and are not used as manufacturer-certified durability, steering-precision or impact-resistance data.
MANUFACTURER DATA NOT PUBLISHED
CEN's current public listing does not publish servo-horn center-to-center length, spring rate, saver preload, release torque, aluminum alloy grade, anodizing specification, total weight, retaining-screw size or recommended tightening torque. Those values are intentionally not estimated or invented.
Product designation, 25T spline, CNC-aluminum construction, black-anodized finish, non-lifted F450 fitment restriction, current manufacturer price and review count were checked against CEN Racing. Two verified distinct images are retained; no duplicate imagery was added solely to increase gallery count.
