Draw-Tite has designed custom-fit trailer hitches since 1946 and is one of North America's most widely fitted hitch brands. Receiver hitches use solid all-welded construction and low-profile designs that follow modern vehicle contours, install with minimal bumper cutting or drilling, meet or exceed V5 CSA and SAE J684 standards, and carry a limited lifetime warranty.
Draw-Tite has been leading custom-fit trailer hitch design and engineering since its founding in 1946, and it remains one of the most widely fitted hitch brands in North America. The company's stated approach is straightforward: every hitch is tested rigorously so that it performs well beyond published industry standards, a philosophy it markets as Tested Tough. It sits within the Horizon Global towing group alongside Reese, Fulton, Bulldog, Tekonsha, Bargman and Wesbar.
Custom fit is the defining characteristic. Rather than adapting a universal design, Draw-Tite engineers a trailer hitch for a specific make, model and model year, so it bolts to existing frame locations with minimal bumper cutting or drilling. Low-profile designs follow the rear contours and aerodynamic styling of modern vehicles, which matters more than it once did now that rear fascias are shaped and sensor-equipped. Construction is solid all-welded steel for maximum strength, and every hitch meets or exceeds V5 CSA and SAE J684 standards and is backed by a nationwide limited lifetime warranty.
The range spans receiver sizes and classes to suit different loads, from 1-1/4 inch receivers for bike racks, cargo carriers and light trailers up through 2 inch receivers for heavier towing. Front mount hitches add a receiver at the front of the vehicle for winch mounts, snow plows, spare carriers and precise trailer positioning.
The Hidden Hitch series takes concealment further by mounting behind the vehicle's rear fascia, so the vehicle keeps its factory appearance until a removable receiver is fitted. Each is custom designed per make and model for a no-drill installation that does not compromise ground clearance, rated for up to 3,500 pounds gross trailer weight and 350 pounds tongue weight. Matching plug-and-play wiring completes the towing system.

Yes, part number 36538 is designed for the Chevrolet Impala. However, the Impala requires minor fascia trimming during installation. You must obtain the vehicle owner's permission before trimming. A tape measure is also required for Impala installation.
Yes, part number 36538 fits the Buick LaCrosse. However, you must use bracket "B" (not bracket "A") and you will need to enlarge the rearward hole on the vehicle suspension mount to accept a ½" bolt using a ½" drill bit. See Figure 3 in the manual for the location.
Yes. On the Cadillac XTS, you must enlarge the rearward hole on the vehicle suspension mount to accept a ½" bolt. Use a ½" drill bit to enlarge this hole. See Figure 3 in the manual for the location.
Use bracket "B" on the Buick LaCrosse. Bracket "A" is used on Chevrolet Malibu, Chevrolet Impala, Buick Regal, and Cadillac XTS. Bracket "B" is also used on all FWD models before mid-year 2013 with a wedge spacer.
No. The wedge spacer (item 11) is required only on FWD models before mid-year 2013. If your Malibu is mid-year 2013 or later, you do not need the spacer. Use bracket "A" without the spacer.
You will need wrenches in sizes 10mm, 13mm, 9/16", and 3/4". A tape measure is required only for Impala models. A ½" drill bit is required only for Buick LaCrosse and Cadillac XTS models to enlarge the suspension mount hole.
The hitch includes: 2× M8 × 1.25 × 55mm hex bolts (CL10.9), 5× ½-13 hex nuts, 4× ½" flat washers, 1× ½-13 × 1.50" hex bolt (GR5), 2× 3/8" conical washers, 1× ½-13 × 2.00" hex bolt (GR5), 2× M8 × 1.25 hex nuts, 1× ½-13 handle nut, 4× ½-13 × 1.50" carriage bolts (GR5), 7× ½" conical washers, 1× wedge spacer, and 2× 5/16" flat washers. The fastener kit 36538F is sold separately.
The manual does not specify whether the tailpipe must be removed. However, Step 1 requires you to remove and replace the existing inner tailpipe hanger 8mm bolt on both sides. Consult the vehicle service manual or a professional installer to determine if tailpipe removal is necessary for access.
1. Remove and replace the inner tailpipe hanger 8mm bolts on both sides. 2. Install the forward hitch bracket (A or B depending on model) and hand-tighten only. 3. Raise the rearward section of the hitch over the 8mm bolts and hand-tighten. 4. Install the ½" carriage bolts into the hitch support plate. 5. Raise the center section and hand-tighten. 6. Attach the forward end of the center section to the forward bracket and hand-tighten. 7. Torque all fasteners to specification. Do not fully tighten any fasteners until Step 7.
Hand-tighten all fasteners during Steps 1–6. Only in Step 7, after all sections are in place and aligned, should you use a torque wrench to tighten all fasteners to their final specifications. This allows the hitch sections to pivot and align properly before final tightening.
For Chevrolet Impala and Cadillac XTS models, use the forward holes on the support plate when installing the ½" carriage bolts in Step 4. For Chevrolet Malibu, Buick Regal, and Buick LaCrosse models, use the rearward holes.
The conical washers must be installed with the teeth side against the hitch. This orientation is critical for proper fastening and load distribution.

Open the tailgate. On the driver's side, inside the vehicle behind the taillights, remove the plastic cover and pull back the insulation liner to access the plastic wing nut holding the taillight in place. Unscrew the plastic wing nut and carefully pry the taillight housing assembly away from the vehicle, being careful not to break the alignment tabs. Carefully separate the vehicle's plugs. Repeat for the passenger's side.
On both driver's and passenger's sides, slit the grommet to allow the T-One T-Connector wiring to pass through. Route the T-One T-Connector ends containing the yellow and brown wires through the hole and into the tail lamp pocket, then reseat the grommet around the wires. Leave the 4-flat connector and black converter box in the cargo area during this step.
Insert the T-One T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place. Ensure all connector surfaces are clean and free of dirt, do not damage the locking tabs, and verify that connectors are fully inserted with locking tabs in place.
Route the T-One T-Connector containing the green and red wires below the threshold cover to the passenger's side taillight housing. Repeat the same insertion and locking procedure used for the yellow wire connector in Step 3.
Route the 4-flat connector through the driver's side trim panel into the side storage compartment and store it there when not in use.
On the driver's side, locate a flat surface in an out-of-the-way place and mount the T-One T-Connector's black converter box using the double-sided tape provided.
Yes. You must drill a 3/32" hole to establish a grounding point for the white grounding wire. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
Locate a suitable grounding point on the vehicle. Drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Do not drill into any exposed surfaces.
On the driver's side, locate the red 12 gauge power wire from the T-One T-Connector box. Attach the black 12 gauge wire provided to this red wire.
You may either route the black wire through a grommet and along the exterior frame, or follow the existing wiring along the thresholds into the engine compartment up to the battery. In both cases, avoid areas that may pinch or break the wire. If routing through a grommet and along the exterior, carefully avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Disconnect the vehicle's negative (-) battery cable. If not already removed, remove the fuse from the yellow fuse holder provided. Cut the fuse holder wire, attach the ring terminal, and secure it to the vehicle's positive (+) battery cable. Connect the other end of the fuse holder to the black 12 gauge wire using the yellow butt connector provided.
Install a 10 amp fuse into the fuse holder after reconnecting the vehicle's negative (-) battery cable.
Secure the remainder of the T-One T-Connector harness with the cable ties provided to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut, or melt the wire.
Reinstall the plastic trim panels, threshold, storage covers, floor covering, and other items removed during installation. Be careful not to pinch or cut the wires.
All connections must be complete for the T-One T-Connector to function properly. Test and verify installation with a test light or trailer once installed. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition.
Do not exceed the lower of the towing manufacturer rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product. Overloading circuits can cause fires. Refer to your vehicle's owner's manual and the product documentation for specific amperage ratings.
Always wear safety glasses and use all safety precautions during installation. Read and follow all warnings and instructions included with the product before beginning installation. Read and follow all warnings and cautions printed on the tow vehicle's battery.
