- The Jeep Wrangler YJ service manual provides exact torque specifications and the order to follow when rebuilding an engine. Many companies provide aftermarket parts for this task. Weber makes replacement carburetors, Clifford makes exhaust manifolds, while MSD makes electronic ignitions and other parts for upgrading the exterior and interior of the 4.0-liter HO engine.
- With many Jeeps more than 20-years-old, their suspensions begin to show signs of wear. Replacement suspension components and lift kits restore the service life of the Jeep Wrangler. Modest lifts of 2 inches to 3 inches with replacement shock absorbers enhance the off-road ability of the Jeep. Taller lifts of 4 inches or more drastically improve the approach and departure angles for rock crawling or mud driving.
- Skid plates and rocker panels act like armor for the Jeep Wrangler. As the Wrangler drives over large rocks and boulders, these plates and panels protect the undercarriage and body from damage and helps keep the driver and other occupants safe.
