Frequently Asked Questions About Kenworth W900A Chrome Stacks & Tops

What are the differences between curved and straight chrome stacks for my W900A?

Curved chrome stacks typically measure 5 or 6 inches in diameter and feature a 30 to 45-degree bend, offering better clearance for cab-mounted accessories and a classic West Coast look. Straight stacks provide a more traditional appearance and are easier to install but may require careful positioning to avoid interference with mirrors or antennas. Both styles are available in 36, 48, and 60-inch lengths, with curved stacks generally sitting 6-12 inches closer to the cab than straight configurations.

Will these chrome stacks fit my specific year Kenworth W900A, and what adapters might I need?

Chrome stacks designed for the W900A typically fit models from 1961 through 1985, though mounting brackets and exhaust pipe diameters can vary. Pre-1970 models often require 5-inch to 4-inch reducers, while 1971-1985 models usually have standard 5-inch exhaust systems. Always verify your existing exhaust pipe outer diameter before ordering. Most installations require stack clamps, which are sold separately and range from 4 to 6 inches depending on your setup.

How difficult is the installation process, and what tools will I need?

Installation typically takes 2-3 hours per stack and requires basic hand tools including socket wrenches, a torque wrench, and potentially a sawzall for trimming existing exhaust pipes. The most challenging aspect is usually aligning the stacks perfectly vertical and ensuring equal spacing from the cab. Many customers recommend having a helper to hold stacks in position during mounting. Professional installation averages $200-400 if you prefer expert alignment and secure mounting.

What gauge chrome and finish options provide the best durability against rust and pitting?

Premium stacks feature 16-gauge steel construction with triple-chrome plating for maximum corrosion resistance. Budget options may use 18 or 20-gauge steel with standard chrome plating that can show pitting within 12-18 months in harsh climates. Look for stacks with nickel underplating beneath the chrome layer, as this significantly improves longevity. Polished 304 stainless steel alternatives are available for extreme durability but cost approximately 40% more than chrome-plated options.

Do chrome stack tops actually improve performance or are they purely aesthetic?

Chrome stack tops serve both functional and aesthetic purposes. Curved or angled rain caps effectively prevent water intrusion during heavy rain or truck wash operations, which can cause exhaust system corrosion and engine problems. Straight-cut tops offer minimal weather protection but provide the loudest exhaust note. Miter-cut tops balance appearance and function, deflecting moderate rainfall while maintaining good exhaust flow. Performance impact is negligible, with most tops creating less than 1% exhaust restriction.
