Reese has designed towing equipment since 1952 and remains a benchmark for heavy-duty towing. The line covers fifth wheel hitches such as the modular M5, gooseneck couplers including the Goose Box, air-ride and short-bed pin boxes, weight distribution systems with active sway control, and the accessories that connect them, all built to exceed published industry standards.
Reese has been pioneering towing performance since 1952, when Margaret Reese asked her husband TJ to stop travel trailers rocking every time somebody walked through them. His answer, the first pair of stabilising jacks, was simple and effective enough to change the RV industry. From that starting point Reese grew into a designer and manufacturer of complete towing systems, and today it anchors the heavy-duty end of the Horizon Global towing portfolio.
Fifth wheel towing is where the brand's engineering is most visible. The M5 fifth wheel hitch uses a modular design that breaks into manageable sections for assembly, with a wider stance, tighter tolerances and a shock absorption system aimed at the jolts that travel up through a truck bed. For owners who would rather tow from a gooseneck coupler and keep the bed clear, the Goose Box 20K replaces the trailer's king pin with a gooseneck connection carrying its own air-ride cushioning.
Pin boxes are a Reese speciality. The 5th Airborne uses air-ride technology to dampen road shock and reduce the chucking motion that makes fifth wheel towing tiring, while the Sidewinder was designed for short-bed pickups, pivoting the connection point so the trailer can turn sharply without the front cap meeting the cab.
For conventional towing, Reese weight distribution systems restore load to the tow vehicle's front axle and control sway. The Pro Round Bar distributes weight evenly while damping sway, and the Pro Dual Cam II uses active cam-based sway control that works harder the stronger the sway force becomes. Complete kits pair bars, head and shank to a rated tongue weight, and dedicated sway control kits can be added to existing setups. The products suit RV owners, horse and livestock haulers and anyone towing near the upper end of a vehicle's rating.

The N58305 is a bolt-on chain hanger assembly designed to attach to trailer frames and work with weight distribution (W.D.) hitches. It provides a mounting point for the safety chain that connects the trailer to the tow vehicle. The chain hanger holds the spring bar chain in the correct position during towing.
Yes, the N58305 is designed for both tube frame and C-channel frame trailers. However, the mounting position differs: for tube frames, locate the top of the chain hanger plate 1/4" down from the top of the frame; for C-channel frames, locate it 1/2" down from the top of the frame.
The N58305 is compatible with Reese, Draw-Tite, and Pro Series weight distribution hitches. The distance from the coupler ball center to the chain hanger center varies by hitch type: Reese and Draw-Tite trunnion models require 30", Reese and Draw-Tite round bar models require 28-5/8", Pro Series trunnion models require 28", and Pro Series round bar models require 26-5/8".
You will need a drill with a 1/2" drill bit, a center punch, a wrench or socket to tighten the lock nuts, and a jack with a wood block to raise the trailer during hookup. The manual does not specify additional tools required for installation.
The manual shows that the assembly includes bolts, washers (flat and tooth washers), lock nuts, a spring clip, and the chain hanger hook itself. The exact quantity and specifications of each component are not detailed in the manual.
Clamp the chain hanger assembly to the trailer frame in the position specified for your hitch type (Step 2 distances). Measure from the center of the coupler ball to the center of the chain hanger. Before drilling, verify that the spring bar chain will hang vertical and check that no wires run through the frame at the drilling location.
Yes, drilling is required. You must drill two 1/2" holes through the trailer frame. For C-channel frames, drill through the frame once. For tube frames, drill through both walls of the tube. Before drilling, mark the center of the slotted hole with a center punch and verify that no wires run in the frame at that location.
You must drill two 1/2" holes through the trailer frame. For C-channel frames, drill through the frame once. For tube frames, drill through both walls of the tube.
After drilling the two 1/2" holes, insert the bolts through the holes in the trailer frame. Install flat washers and lock nuts on the bolts. Tighten the lock nuts so the chain hanger is tight against the trailer frame. Do not over-tighten, as this may cause damage to the trailer frame. Repeat the process for the other side.
Yes, the manual instructs you to repeat Steps 1 through 4 for the other side, indicating that chain hangers must be installed on both sides of the trailer.
Before drilling, verify that no wires run through the frame at the drilling location. Use a center punch to mark the center of the slotted hole before drilling. This prevents damage to electrical wiring or other components inside the frame.
Place a wood block under the jack for extra height and confirm the trailer is stable before proceeding. This prevents the trailer from slipping or tipping during the hookup process.
Slip the closest link of the safety chain over the chain hanger hook. Ensure that loose links are at the bottom of the link that is hooked on the pin. If there are fewer than 5 links between the hook and the U-bolt, adjust the ball mount angle rearward and repeat the procedure. Place the spring clip into the chain hanger hook hole. Repeat for the other side.
Slip the closest link over the chain hanger hook with loose links at the bottom of the hooked link. There should be at least 5 links between the hook and the U-bolt. If fewer than 5 links exist, adjust the ball mount angle rearward and repeat the procedure.
The spring clip is placed into the chain hanger hook hole after the safety chain link is hooked over the hook. It secures the chain in place during towing.
The N58305 fits both tube frame and C-channel frame trailers. Mounting position differs: 1/4" down from the top for tube frames, 1/2" down for C-channel frames.
The N58305 works with Reese, Draw-Tite, and Pro Series weight distribution hitches. Mounting distance varies by brand and model type (trunnion or round bar).
Yes, you must drill two 1/2" holes through the trailer frame. For tube frames, drill through both walls; for C-channel frames, drill through once.
You need a drill with a 1/2" bit, center punch, wrench for lock nuts, and a jack with wood block for raising the trailer during hookup.
Do not over-tighten bolts as this may damage the trailer frame. Avoid drilling into wires in the frame. Use a wood block under the jack when raising the trailer and confirm it is stable.
You must install chain hangers on both sides of the trailer. The installation process is repeated for each side.
