MS2020 8" Shock by James Duff Inc.
MS2020 8" Travel Shock - James Duff Midnight Series by Eibach
Our Price: $119.95

Looking for a more sophisticated shock? Want it to match your Bronco in performance and style? Well, you're in luck. New for 2020 our Midnight Series (MS2020) Shocks built by Eibach in the USA! A shock developed by the industry leaders of Bronco suspension takes you beyond a simple hydraulic shock absorber. the new MS2020 delivers the high performance of a high-pressure monotube gas shock in an affordable package. No need for expensive remote reservoirs, the MS2020 provides a nice comfortable ride on the street while providing the extra dampening needed when the going gets TUFF.

This is our 8" stud eye travel version, please see below for our other lengths and links to purchase. Estimated ship date is early November.

James Duff's MS2020 is the first and only premium shock specifically designed for Bronco's coil spring suspension. It features a 14mm chrome-hardened piston shaft for superior rigidity and minimal seal wear. The shaft itself is coated with a unique black chromate that is actually more durable then chrome, while offering better resistance to rust than other shocks. The machined aluminum rod end offers strength and good looks and houses American-made polyurethane bushings. The shock body itself is constructed of 2” diameter seamless DOM tubing for excellent heat transfer, and the outside of the shock has a durable Midnight Black Metallic powder-coated finish. Inside, the massive 1-3/4" diameter piston has progressive valving that is tuned to provide a smooth ride on the road but has the ability to quickly step up the dampening and effectively smooth out the bumps off-road. Combining race technology with advanced manufacturing techniques, MS2020 shock absorbers are an unbeatable value, especially when considering that most other shock absorbers on the market are made overseas with inferior materials. MS2020 shocks are Made in the USA and Trail Tested Duff Tuff!

  • High pressure monotube gas shock
  • Durable midnight black powder coat
  • Comfortable on-road driving and off-road dampening
  • Eliminates the need for 2 shocks per corner (in several applications)
  • Highest quality, American made budget-friendly shock on the market!
This shock is covered by a 1-year limited warranty.

System B: Basic 3 1/2" Suspension Lift 1966-77 Classic Early Bronco
System B: 3 1/2" Basic Suspension Lift 1966-77 Bronco
Our Price: $545.00

Basic Street and Trail System for those on a budget or don't want dual shocks. 3.5" Progressive Rate Coils, 7° 14 piece Bushing Kit, Large Add-a-leafs, Tracking Bar Drop Bracket, U-Bolts, 4 Shocks with Blue Boots. Our systems are designed so all of the components work together to improve ride and handling under varying conditions. Our suspensions keep in mind the daily driver and full-time four-wheeler, someone who wants to ride comfortably and safely both on the street and on the trail. Designs are based on a Bronco Hardtop with a 302 engine. Less weight (from a 6 cyl or no top) or more weight (from engine swaps, winches, heavy bumpers, etc.) will affect the amount of lift. Our budget oriented systems use add-aleafs for the rear end rather than blocks (which cause stress on u-bolts, u-joints and exaggerate axle wrap). Inspect your leaf springs for sagging, cracks or daylight between leafs before ordering. Add-a-leafs will not make up for tired or cracked leafs. Upgrading to a new leaf spring pack system may be necessary. •Note: If you have a ‘66 with the stock rear stud mount shocks, we recommend upgrading to either a #5500, #5215 or #5214 for maximum travel and performance.
