Toyota Racing Development plans to offer factory-installed TRD Pro off-road kits on the Tacoma, Tundra and 4Runner. The TRD Pro editions -- offered with the same 3-year/36,000-mile warranty as a stock pickup or SUV – will be sold along with four-wheel-drive versions of the light trucks, beginning with the 2015 model year.
Toyota engineers tout the TRD Pro off-road kits as the most advanced off-road package that the carmaker has offered for retail. Jack Hollis, Toyota Division vice president of marketing, remarked that by focusing on authentic performance, they avoided getting into “appearance-over-substance.”
Hollis noted that since TRD Pro parts have a factory warranty, they boast of a high level of durability that short-use racing parts do not. The TRD Pro editions boast of Bilstein monotube shocks with remote reservoirs that add 1 to 2 inches of wheel travel.
The shocks' 60-mm pistons are also larger than the stock units, which means greater damping capabilities. The editions also feature dual cat-back exhaust systems that provide a 10hp boost.
The dual cat-back exhaust systems also have a throatier exhaust note, although not beyond the 95-decibel legal limit. The editions also feature higher ride-height Eibach front springs that add 1 to 2 inches of ground clearance, depending on the vehicle.
Likewise the TRD Pro editions have larger alloy wheels grabbed by knobbier tires for off-road use. TRD also fitted the editions with a 1/4-inch-thick aluminum skid plate under the engine bay. The 4Runner TRD Pro features Multi-Terrain Select, Crawl Control and a locking rear differential.
